manual and all of the warning labels attached to the inverter before installing and operating it, and follow the instructions exactly. Keep this manual handy for quick reference. Definitions and Symbols A safety instruction (message) includes a “Safety Alert Symbol” and a signal word or phrase such as WARNING or CAUTION. Each signal word has the following meaning: !HIGH VOLTAGE This symbol indicates high voltage related warnings. It calls your attention to items or operations that could be dangerous to you and other persons operat- ing this equipment. Read the message and follow the instructions carefully. !WARNING indicates a potentially hazardous situation that, if not avoided, may result in serious injury or death, or minor or moderate injury. Additionally there may be significant property damage. !Caution Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in severe property damage. Step 1 Indicates a step in a series of action steps required to accomplish a goal. The number of the step will be contained in the step symbol. Note Notes indicates an area or subject of special merit, emphasizing either the product's capability or common errors in operation or maintenance. !Tip Tips give a special instruction that can save time or provide other benefits while installing or using the product. The tip calls attention to an idea that may not be obvious to first-time users of the product. 1 Hazardous High Voltage !HIGH VOLTAGE Motor control equipment and electronic controllers are connected to hazard- ous line voltages. When servicing drives and electronic controllers, there may be exposed components with housing or protrusions at or above line potential. Extreme care should be taken to protect against shock. Stand on an insulating pad and make it a habit to use only one hand when checking components. Always work with another person in case an emer- gency occurs. Disconnect power before checking controllers or performing maintenance. Be sure equipment is properly grounded. Wear safety glasses whenever working on electronic controllers or rotating machinery. 1-1 Caution when using Safe Stop Function When using Safe Stop function, make sure to check whether the safe stop function properly works when installation (before starting operation). Please carefully refer to Appendix E Safety (ISO 13849-1) on page 379 General Precautions - Read These First! 2 2 General Precautions - Read These First! !WARNING This equipment must be installed, adjusted, and serviced by qualified electri- cal maintenance personnel familiar with the construction and operation of the equipment and the hazards involved. Failure to observe this precaution may result in bodily injury. !WARNING The user is responsible to ensure that all driven machinery, drive train mecha- nism not supplied by OMRON, and process line material are capable of safe operation at an applied frequency of 150% of the maximum selected fre- quency range to the AC motor. Failure to do so can result in destruction of equipment and injury to personnel should a single-point failure occur. !WARNING For equipment protection, install a ground leakage type breaker with a fast response circuit capable of handling large currents. The ground fault protec- tion circuit is not designed to protect against personal injury. !WARNING HAZARDOUS OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER BEFORE CHANGING WIRING, PUT ON OR TAKE OFF OPTIONAL DEVICES OR REPLACE COOLING FANS. !WARNING Wait at least ten (10) minutes after turning OFF the input power supply before performing maintenance or an inspection. Otherwise, there is the danger of electric shock. !Caution Make sure to read and clearly understand these instructions before working on MX2 series equipment. !Caution Proper grounds, disconnecting devices and other safety devices and their location are the responsibility of the user and are not provided by OMRON !Caution Be sure to connect a motor thermal disconnect switch or overload device to the MX2 series controller to assure that the inverter will shut down in the event of an overload or an overheated motor. !HIGH VOLTAGE Dangerous voltage exists until power light is OFF.

The unbalance factor of the power supply is 3% or higher. 2. the power supply capacity is at least 10 times greater than the inverter ca- pacity (or the power supply capacity is 500 kVA or more). 3. Abrupt power supply changes are expected, due to conditions such as: a) Several inverters are interconnected with a short bus. b) A thyristor converter and an inverter are interconnected with a short bus. c) An installed phase advance capacitor opens and closes. Where these conditions exist or when the connected equipment must be highly reliable, you MUST install an input side AC-reactor of 3% (at a voltage drop at rated current) with respect to the supply voltage on the power supply side. Also, where the effects of an indirect lightening strike are possible, install a lightening conductor. !Caution SUPPRESSION FOR NOISE INTERFERENCE FROM INVERTER The inverter uses many semiconductor switching elements such as transis- tors and IGBTs. Thus, a radio receiver or measuring instrument located near the inverter is susceptible to noise interference. To protect the instruments from erroneous operation due to noise interfer- ence, they should be used well away from the inverter. It is also effective to shield the whole inverter structure. The addition of an EMI filter on the input side of the inverter also reduces the effect of noise from the commercial power line on external devices. Note that the external dispersion of noise from the power line can be mini- mized by connecting an EMI filter on the primary side of the inverter. !Caution When the EEPROM error E08 occurs, be sure to confirm the setting values again.

Note 2 The applicable motor refers to a standard 3-phase motor (4p). When using other motors, care must be taken to prevent the rated motor current (50/ 60 Hz) from exceeding the rated output current of the inverter. Note 3 The output voltage decreases as the main supply voltage decreases (except when using the AVR function). In any case, the output voltage cannot exceed the input power supply voltage. Note 4 To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the maximum allowable rotation speed. Note 5 For achieving approved input voltage rating categories: • 460 to 480 VAC - Over-voltage category 2 • 380 to 460 VAC - Over-voltage category 3 To meet the Over-voltage category 3, insert an EN or IEC standard compliant isolation transformer that is earth grounded and star connected (for Low Voltage Directive). Note 6 At the rated voltage when using a standard 3-phase, 4-pole motor. kW VT 0.2 0.4 0.55 1.1 2.2 3.0 CT 0.1 0.2 0.4 0.75 1.5 2.2 HP VT 1/4 1/2 3/4 1.5 3 4 CT 1/8 1/4 1/2 1 2 3 Rated capacity (kVA) 200 V VT 0.4 0.6 1.2 2.0 3.3 4.1 CT 0.2 0.5 1.0 1.7 2.7 3.8 240 V VT 0.4 0.7 1.4 2.4 3.9 4.9 CT 0.3 0.6 1.2 2.0 3.3 4.5 Loss at 100% load W 12 22 30 48 79 104 Efficiency at rated load % 89.5 90 93 94 95 95.5 Rated input voltage Single-phase: 200 V-15% to 240 V+10%, 50/60 Hz±5% Rated output voltage *3 3-phase: 200 to 240 V (proportional to input voltage) Rated output current (A) VT 1.2 1.9 3.5 6.0 9.6 12.0 CT 1.0 1.6 3.0 5.0 8.0 11.0 Starting torque *6 200% at 0.5 Hz Braking Without resistor 100%: ≤50 Hz 50%: ≤60 Hz 70%: ≤50 Hz 50%: ≤60 Hz 20%: ≤50 Hz 20%: ≤60 Hz With resistor 150% 100% DC braking Variable operating frequency, time, and braking force Weight kg 1.0 1.0 1.1 1.4 1.8 1.8 lb 2.2 2.2 2.4 3.1 4.0 4.0 3 4MX2 Inverter Specifications Section 1-2 Note 7 The braking torque via capacitive feedback is the average deceleration torque at the shortest deceleration (stopping from 50/60 Hz as indicated). It is not continuous regenerative braking torque. The average deceleration torque var- ies with motor loss. This value decreases when operating beyond 50 Hz. If a large regenerative torque is required, the optional regenerative braking unit and a resistor should be used. Note 8 The frequency command is the maximum frequency at 9.8 V for input voltage 0 to 10 VDC, or at 19.6 mA for input current 4 to 20 mA. If this characteristic is not satisfactory for your application, contact your Omron representative. Note 9 If the inverter is operated outside the region shown in the graph in the derating curve, the inverter may be damaged or its service life may be shortened. Set  Carrier Frequency Adjustment in accordance with the expected output current level. See derating curve section for the detailed information of the inverter operating range. Note 10 The storage temperature refers to the short-term temperature during transpor- tation. Note 11 Conforms to the test method specified in JIS C0040 (1999). For the model types excluded in the standard specifications, contact your Omron sales rep- resentative. Note 12 Watt losses are calculated values based on specification of main semi-con- ductors. You must take suitable margin when designing cabinet based on these values. Otherwise there is a possibility of heating trouble.

Choosing a higher carrier frequency tends to decrease audible noise, but it also increases the internal heating of the inverter, thus decreasing (derating) the maximum current output capability. Ambient temperature is the temperature just outside the inverter housing such as inside the control cabinet where the inverter is mounted. A higher ambient temperature decreases (derates) the inverter's maximum current output capacity. An inverter up to 4.0 kW may be mounted individually in an enclosure or side- by-side with other inverter(s) as shown below. Side-by-side mounting causes greater derating than mounting inverters separately. Graphs for either mount- ing methods are included in this section. Refer to Installation Environment clearance on page 31 for minimum clearance dimensions for both mounting configurations.

14Introduction to Variable-Frequency Drives Section 1-3 1-3 Introduction to Variable-Frequency Drives 1-3-1 The Purpose of Motor Speed Control for Industry Omron inverters provide speed control for 3-phase AC induction motors. You connect AC power to the inverter, and connect the inverter to the motor. Many applications benefit from a motor with variable speed, in several ways: • Energy savings - HVAC • Need to coordinate speed with an adjacent process - textile and printing presses • Need to control acceleration and deceleration (torque) • Sensitive loads - elevators, food processing, pharmaceuticals 1-3-2 What is an Inverter The term inverter and variable-frequency drive are related and somewhat interchangeable. An electronic motor drive for an AC motor can control the motor's speed by varying the frequency of the power sent to the motor. An inverter, in general, is a device that converts DC power to AC power. The figure below shows how the variable-frequency drive employs an internal inverter. The drive first converts incoming AC power to DC through a rectifier bridge, creating an internal DC bus voltage. Then the inverter circuit converts the DC back to AC again to power the motor. The special inverter can vary its output frequency and voltage according to the desired motor speed. Power Input L1 L2 L3 The simplified drawing of the inverter shows three double-throw switches. In Omron inverters, the switches are actually IGBTs (insulated gate bipolar tran- sistors). Using a commutation algorithm, the microprocessor in the drive switches the IGBTs on and off at a very high speed to create the desired out- put waveforms. The inductance of the motor windings helps smooth out the pulses. 1-3-3 Torque and Constant Volts/Hertz Operation In the past, AC variable speed drives used an open loop (scalar) technique to control speed. The constant-volts-hertz operation maintains a constant ratio between the applied voltage and the applied frequency. With these conditions, AC induction motors inherently delivered constant torque across the operating speed range. For some appli- cations, this scalar technique was ade- quate. Variable-frequency Drive Output voltage V0 Output frequency Motor Converter Internal Inverter Rectifier DC Bus U/T1 V/T2 W/T3 Constant torque f 100%

Introduction to Variable-Frequency Drives Section 1-3 Today, with the advent of sophisticated microprocessors and digital signal pro- cessors (DSPs), it is possible to control the speed and torque of AC induction motors with unprecedented accuracy. The MX2 utilizes these devices to per- form complex mathematical calculations required to achieve superior perfor- mance. You can choose various torque curves to fit the needs of your application. Constant torque applies the same torque level across the fre- quency (speed) range. Variable torque, also called reduced torque, lowers the torque delivered at mid-level frequencies. A torque boost setting will add addi- tional torque in the lower half of the frequency range for the constant and vari- able torque curves. With the free-setting torque curve feature, you can specify a series of data points that will define a custom torque curve to fit your appli- cation. 1-3-4 Inverter Input and Three-phase Power The Omron MX2 Series of inverters includes two sub-groups: the 200 V class and the 400V class inverters. The drive described in this manual may be used in either the United States or Europe, although the exact voltage level for com- mercial power may be slightly different from country to country. Accordingly, a 200 V class inverter requires (nominal) 200 to 240 VAC, and 400 V class inverter requires from 380 to 480 VAC. The 200 V class inverters MX2-B accept single-phase 200 V class input volt- age, those MX2-2 three-phase power only. All 400 V class inverters require three-phase power supply. !Tip If your application only has single phase power available, refer to MX2 inverter of 3HP or less; they can accept single phase input power. Note: Larger mod- els may be able to accept single-phase with derating. Contact your Omron distributor for assistance. The common terminology for single phase power is line (L) and Neutral (N). Three-phase power connections are usually labeled Line 1 [R/L1], Line 2 [S/ L2] and Line 3 [T/L3]. In any case, the power source should include an earth ground connection. That ground connection will need to connect to the inverter chassis and to the motor frame (see “Wire the Inverter Output to Motor” in section 2-3-12 (page 51) and “Inverter output terminal (U/T1, V/T2, W/T3)” in section 2-3-9 (page 47)). 1-3-5 Inverter Output to the Motor The AC motor must be connected only to the inverter's output terminals. The output terminals are uniquely labeled (to differentiate them from the input terminals) with the designations U/T1, V/T2, and W/T3. This cor- responds to typical motor lead connection designations T1, T2, and T3. It is often not necessary to connect a particular motor lead for a new application. The conse- quence of swapping any two of the three connections is the reversal of the motor direction. In applications where reversed rotation could cause equipment dam- age or personnel injury, be sure to verify direction of rotation before attempting full-speed operation. For safety to personnel, you must connect the motor chassis ground to the ground connection at the bottom of the inverter housing. Notice the three connections to the motor do not include one marked “Neutral” or “Return”. The motor represents a balanced “Y” impedance to the inverter, so there is no need for a separate return. In other words, each of the three “Hot” connections serves also as a return for the other connections, because of their phase relationship. 3-phase AC motor U/T1 W/T3 V/T2 Earth GND 15

16Introduction to Variable-Frequency Drives Section 1-3 The Omron inverter is a rugged and reliable device. The intention is for the inverter to assume the role of controlling power to the motor during all normal operations. Therefore, this manual instructs you not to switch off power to the inverter while the motor is running (unless it is an emergency stop). Also, do not install or use disconnect switches in the wiring from the inverter to the motor (except thermal disconnect). Of course, safety-related devices such as fuses must be in the design to break power during a malfunction, as required by NEC and local codes. 1-3-6 Intelligent Functions and Parameters Much of this manual is devoted to describing how to use inverter functions and how to configure inverter parameters. The inverter is micro-processor- controlled, and has many independent functions. The microprocessor has an on-board EEPROM for parameter storage. The inverter's front panel keypad provides access to all functions and parameters, which you can access through other devices as well. The general name for all these devices is the digital operator, integrated operator, or digital operator panel. Chapter 2 will show you how to get a motor running, using a minimal set of function com- mands or configuring parameters. The optional read/write programmer will let you read and write inverter EEPROM contents from the programmer. This feature is particularly useful for OEMs who need to duplicate a particular inverter's settings in many other inverters in assembly-line fashion. 1-3-7 Braking In general, braking is a force that attempts to slow or stop motor rotation. So it is associated with motor deceleration, but may also occur even when the load attempts to drive the motor faster than the desired speed (overhauling). If you need the motor and load to decelerate quicker than their natural deceleration during coasting, we recommend installing a braking resistor. The dynamic braking unit (built into MX2) sends excess motor energy into a resistor to slow the motor and load (See “Introduction” in section 5-1 (page 255) and “Dynamic Braking” in section 5-3 (page 262) for more information). For loads that continuously overhaul the motor for extended periods of time, the MX2 may not be suitable (contact your Omron distributor). The inverter parameters include acceleration and deceleration, which you can set to match the needs of the application. For a particular inverter, motor, and load, there will be a range of practically achievable accelerations and deceler- ations.

Introduction to Variable-Frequency Drives Section 1-3 1-3-8 Velocity ProfilesThe MX2 inverter is capable of sophisticated speed control. A graphical representation of that capability will help you understand and configure the associated param- eters. This manual makes use of the velocity profile graph used in indus- try (shown at right). In the example, acceleration is a ramp to a set speed, and deceleration is a decline to a stop. Acceleration and deceleration set- tings specify the time required to go from a stop to maximum frequency (or vise versa). The resulting slope (speed change divided by time) is the acceleration or deceleration. An increase in output frequency uses the acceleration slope, while a decrease uses the deceleration slope. The accel or decel time a par- ticular speed change depends on the starting and ending frequencies. However, the slope is constant, corresponding to the full-scale accel or decel time setting. For example, the full-scale acceleration setting (time) may be 10 seconds - the time required to go from 0 to 60 Hz. The MX2 inverter can store up to 16 preset speeds. And, it can apply separate acceleration and decelera- tion transitions from any preset to any other preset speed. A multi- speed profile (shown at right) uses two or more preset speeds, which you can select via intelligent input terminals. This external control can apply any preset speed at any time. Alternatively, the selected speed is infinitely variable across the speed range. You can use the potentiometer control on the keypad for manual control. The drive accepts analog 0-10 VDC signals and 4-20 mA control signals as well. The inverter can drive the motor in either direction. Separate FW and RV commands select the direction of rotation. The motion profile example shows a forward motion followed by a reverse motion of shorter duration. The speed presets and analog sig- nals control the magnitude of the speed, while the FWD and REV commands determine the direction before the motion starts. Note The MX2 can move loads in both directions. However, it is not designed for use in servo-type applications that use a bipolar velocity signal that deter- mines direction.

18Frequently Asked Questions Section 1-4 1-4 Frequently Asked Questions Q. What is the main advantage in using an inverter to drive a motor, com- pared to alternative solutions? A. An inverter can vary the motor speed with very little loss of efficiency, unlike mechanical or hydraulic speed control solutions. The resulting ener- gy savings usually pays for the inverter in a relatively short time. Q. The term “inverter” is a little confusing, since we also use “drive” and “amplifier” to describe the electronic unit that controls a motor. What does “inverter” mean? A. The term inverter, drive, and amplifier are used somewhat interchange- ably in industry. Nowadays, the term drive, variable-frequency drive, vari- able-speed drive, and inverter are generally used to describe electronic, microprocessor-based motor speed controllers. In the past, variable- speed drive also referred to various mechanical means to vary speed. Am- plifier is a term almost exclusively used to describe drives for servo or step- per motors. Q. Although the MX2 inverter is a variable speed drive, can I use it in a fixed- speed application? A. Yes, sometimes an inverter can be used simply as a “soft-start” device, providing controlled acceleration and deceleration to a fixed speed. Other functions of the MX2 may be useful in such applications, as well. However, using a variable speed drive can benefit many types of industrial and com- mercial motor applications, by providing controlled acceleration and decel- eration, high torque at low speeds, and energy savings over alternative solutions. Q. Can I use an inverter and AC induction motor in a positioning application? A. That depends on the required precision, and the slowest speed the mo- tor must turn and still deliver torque. The MX2 inverter will deliver full torque while turning the motor at 6Hz (180RPM). DO NOT use an inverter if you need the motor to stop and hold the load position without the aid of a mechanical brake (use a servo or stepper motion control system). Q. Can the inverter be controlled and monitored via a network? A. Yes. MX2 inverters have built-in ModBus communications. See Appen- dix B for more information on network communications. Q. Why does the manual or other documentation use terminology such as “200 V class” instead of naming the actual voltage, such as “230 VAC” A. A specific inverter model is set at the factory to work across a voltage range particular to the destination country for that model. The model spec- ifications are on the label on the side of the inverter. A European 200V class inverter (“EU” marking) has different parameter settings than a USA 200 V class. Q. Why doesn't the motor have a neutral connection as a return to the inverter? A. The motor theoretically represents a “balanced Y” load if all three stator windings have the same impedance. The Y connection allows each of the three wires to alternatively serve as input or return on alternate half-cycle.

Frequently Asked Questions Section 1-4 Q. Does the motor need a chassis ground connection? A. Yes, for several reasons. Most importantly, this provides protection in the event of a short in the motor that puts a hazardous voltage on its housing. Secondly, motors exhibit leakage current that increase with aging. Lastly, a grounded chassis generally emits less electrical noise than an unground- ed one. Q. What type of motor is compatible with the Omron inverters? A. Motor type - It must be a three-phase AC induction motor. Use an in- verter-grade motor that has at least 800V insulation for 200V class invert- ers, or 1600V insulation for 400V class. Motor size - In practice, it's better to find the right size motor for your ap- plication; then look for the inverter to match the motor. Note There may be other factors that will affect motor selection, including heat dis- sipation, motor operating speed profile, enclosure type, and cooling method. Q. How many poles should the motor have? A. Omron inverters can be configured to operate motors with 2, 4, 6, or 8 poles. The greater the number of the poles, the slower the top motor speed will be, but it will have higher torque at the base speed. Q. Will I be able to add dynamic (resistive) braking to my Omron MX2 drive after the initial installation? A. Yes, the MX2 inverter already has a dynamic braking circuit built in. Just add the resistor sized to meet the braking requirements. For more informa- tion, contact your nearest Omron representative. Q. How will I know if my application will require resistive braking? A. For new applications, it may be difficult to tell before you actually test a motor/drive solution. In general, some application can rely on system loss- es such as friction to serve as the deceleration force, or otherwise can tol- erate a long decel time. These applications will not need dynamic braking. However, applications with a combination of a high-inertia load and a re- quired short decel time will need dynamic braking. This is a physics ques- tion that may be answered either empirically or through extensive calculations. Q. Several options related to electrical noise suppression are available for the Omron inverters. How can I know if my application require any of these options? A. The purpose of these noise filters is to reduce the inverter electrical noise so the operation of nearby electrical devices is not affected. Some applications are governed by particular regulatory agencies, and noise suppression is mandatory . in those cases, the inverter must have the cor- responding noise filter installed. Other applications may not need noise suppression, unless you notice electrical interference with the operation of other devices. 19 20International Standards Section 1-5 Q. The MX2 features a PID control. PID loops are usually associated with water control, flow control processes, heating, or process industries in gen- eral. How could the PID loop feature be useful in my application? A. You will need to determine the particular main variable in your applica- tion the motor affects. That is the process variable (PV) for the motor. Over time, a faster motor speed will cause a faster change in the PV than a slow motor speed will. By using the PID loop feature, the inverter commands the motor to run at the optimal speed required to maintain the PV at the de- sired value for current conditions. Using the PID loop feature will require an additional sensor and other wiring, and is considered an advanced appli- cation. 1-5 International Standards The 3G3MX2 series inverters meet the following international standards.

Look for any damage that may have occurred during transportation. 2. Verify the contents of the box. 3. Inspect the specifications label on the side of the inverter. Make sure it matches the product part number you ordered. 2-1-2 Main Physical Features

The MX2 Series inverters vary in size according to the current output rating and motor size for each model number. All feature the same basic Keypad and con- nector interface for consistent ease of use. The inverter construction has a heat sink at the back of the housing. The larger models include a fan to enhance heat sink performance. The mounting holes are predrilled in the heat sink for your conve- nience. Smaller models have two mount- ing holes, while larger ones have four. Be sure to use all the mounting holes pro- vided. Never touch the heat sink during or just after operation; it can be very hot. The electronics housing and front panel are built onto the front of the heat sink. Inverter Keypad - The inverter uses a digital operator interface, or keypad. The four-digit display can show a variety of performance parameters. LEDs indicate whether the display units are Hertz or Amperes. Other LEDs indicate Power (external), and Run/Stop mode and Pro- gram/Monitor Mode status. Membrane keys Run and Stop/Reset control monitor operation. The , , and keys allow an operator to navigate to the inverter's functions and parameter values. The key is used when changing a parameter. 8.8.8.8. 21

22Orientation to Inverter Features Section 2-1 Power Wiring Access - First, ensure no power source is connected to the inverter. If power has been connected, verify that the Power LED is OFF and then wait ten minutes after power down to proceed. After removing the termi- nal cover and front housing cover, the housing partitions that cover the power and motor wiring exits will be able to slide upward as shown below. Notice the four wire exit slots in the housing partition. This helps keep the power and motor wiring (to the left) separated from the signal-level logic or analog wiring (to the right). Remove the housing partition and as shown as set them aside in a secure place while wiring. Be sure to replace them afterward. Never operate the inverter with the partition removed or the front housing cover removed. The power input and motor 3-phase wiring connect to the lower row of the ter- minals. The upper row of power terminals connect to optional braking units or DC link choke. The following section in this chapter will describe system design and guide you through a step-by-step installation process. After the section on wiring, this chapter will show how to use the front panel keys to access functions and edit parameters. Note The housing partition can be removed without removing the front cover in the following models.

If you are connecting a motor to the inverter on a test bench just to get started, that's all you may need for now. But a system can also have a variety of additional components. Some can be for noise suppression, while others may enhance the inverter's braking perfor- mance. The figure and table below show a system with all the optional com- ponents you might need in your finished application. From power supply Motor Thermal switch Note Note that some components are required for regulatory agency compliance (see SECTION 5 Inverter System Accessories and Appendix D CE-EMC Installation Guidelines). Name Function Breaker / disconnect A molded-case circuit breaker (MCCB), ground fault interrupter (GFI), or a fused Breaker, disconnect device.

Step-by-Step Basic Installation Section 2-3 !WARNING In the cases below involving a general-purpose inverter, a large peak current can flow on the power supply side, sometimes destroying the converter mod- ule: 1. The unbalance factor of the power supply is 3% or higher. 2. The power supply capacity is at least 10 times greater than the inverter capacity (or the power supply capacity is 500k VA or more). 3. Abrupt power supply changes are expected, due to conditions such as: a. Several inverters are interconnected with a short bus. b. A thyristor converter and an inverter are interconnected with a short bus. c. An installed phase advance capacitor opens and closes. Where these conditions exist or when the connected equipment must be highly reliable, you MUST install an input-side AC reactor of 3% (at a voltage drop at rated current) with respect to the supply voltage on the power supply side. Also, where the effects of an indirect lightning strike are possible, install a lightning conductor. 2-3 Step-by-Step Basic Installation This section will guide you through the following basic steps of installation: Step Activity Page 1 Choose a mounting location in compliance with the Warnings and Cautions. See notes below. Note If the installation is in an EU country, study the EMC installation guidelines in Appendix D CE-EMC Installation Guidelines.

Be sure to use lock washers or other means to ensure screws do not loosen due to a vibration. 2-3-2 Installation Environment clearance Make sure the ambient temperature remains within the rated range (-10 to 50°C). Take note that if the ambient temperature reaches or exceeds 40°C, the carrier frequency and output current must be derated (check derating tables per each inverter model in Derating Curves on page 9). If the Inverter is used in an environment exceeding the allowable operating temperature range, the product life of the Inverter (specifically, the capacitor) will be shortened. Measure and check the temperature approx. 5 cm from the bottom center of the Inverter body. Provide sufficient space around the Inverter because it can become very hot (up to 150°C or so). Or provide the right air ventilation forced cooling flow when designing the enclosure : 100 mm or more 50 mm or more Provide sufficient space so that the top Air flow and bottom wiring ducts, etc. will not obstruct the flows of cooling air. 100 mm or more r etrevnIWall 31 32Step-by-Step Basic Installation Section 2-3 Keep the Inverter away from heating elements (such as a Braking Resistor, reactor, etc.). Although side-by-side installation is possible. The ambient temperature of the installation site must not exceed 40°C and the carrier frequency and output current must be derated if side-by-side installation is used. For details check Derating Curves on page 9. Make sure that the humidity in the installation site is within the allowable oper- ating range (20% to 90% RH), as defined in the standard specifications.

Check for any loosening of screws. Otherwise, there is the danger of fire. Types Screw Diameter 2-3-8 Inverter Supply Input (R/L1, S/L2, T/L3) Step 3 In this step, you will connect wiring to the input of the inverter. First, you must determine whether the inverter model you have required three-phase power only with terminals [R/L1], [S/L2], and [T/L3], or single-phase power only with terminals [L1] and [N]. Refer to the specifications label (on the side of the inverter) for the acceptable power source types! 2-3-8-1 Earth leakage circuit breaker Use an earth leakage breaker for circuit (wiring) protection between the power supply and the main power supply terminals (R/L1, S/L2, T/L3). An earth leakage breaker may malfunction at high frequencies as those gen- erated by an inverter. Use an earth leakage breaker with a large high-fre- quency sensitive current rating. When sensitivity of 30mA or even less earth leakage maybe required in cer- tain applications (e.g. domestic), short motor cable and convenient low-leak- age EMC filters should be selected. Check with your supplier for additional indications. 2-3-8-2 Magnetic contactor When the Inverter protective function is activated, your system may fail or an accident may occur. Connect a magnetic contactor to turn off the Inverter power supply. Do not start or stop the Inverter by switching ON/OFF the magnetic contactor provided in the Inverter power supply input (primary) circuit and output (sec- ondary) circuit.To start or stop the Inverter via an external signal, use the operation command terminals (FW, RV) on the control circuit terminal block. Do not use this Inverter with an input phase loss connection. The Inverter operating with 1-phase input may be causing a trip (due to undervoltage, overcurrent, etc.) or damage to the Inverter. Do not turn on the power and then turn it off again more than once every 3 minutes. Doing so may damage the Inverter.

Otherwise, the output voltage between the Inverter and the motor may drop. Do not mount a phase advance capacitor or surge absorber, because these devices may cause the Inverter to trip or cause damage to the capacitor or surge absorber. If the cable length exceeds 20 m (particularly, with 400 V class), a surge volt- age may be generated at the motor terminal depending on stray capacitance or inductance of the cable, causing the motor to risk his isolation (depending on motor isolation class and conditions). To suppress surge voltage, output filters are recommended. From simple choke and output dV/dt filters to sinus filters. To connect several motors, provide a thermal protection relay for each, as the inverter can not recognize how current is shared among the motors. The RC value of each thermal relay should be 1.1 times larger than the motor rated current.The relay may trip earlier depending on the cable length.In this case, connect an AC reactor to the Inverter output. 2-3-10 DC Reactor Connection (+1, P/+2) This terminal is used to connect the optional DC reactor. By factory default, a shorting bar has been connected between terminals +1 and P/+2. Before connecting the DC reactor, remove this shorting bar. The length of the DC reactor connection cable should be 5 m or shorter. If the DC reactor is not being used, do not remove the shorting bar. If you remove the shorting bar without connecting the DC reactor, no power is supplied to the Inverter main circuit, disabling operation. 2-3-11 Power connections for each inverter size Single-phase 200 V 0.1 to 0.4 kW Three-phase 200 V 0.1 to 0.75 kW Chassis Ground (M4) Single-phase Three-phase

Note An inverter powered by a portable power generator may receive a distorted power waveform, overheating the generator. In general, the generator capac- ity should be five times that of the inverter (kVA). !Caution Be sure that the input voltage matches the inverter specifications: • Single-phase 200 to 240 V 50/60 Hz(0.1 kW~2.2 kW) for 3G3MX2-AB models • Three-phase 200 to 240 V 50/60 Hz (0.1 kW~15 kW) for 3G3MX2-A2 models • Three-phase 380 to 480 V 50/60 Hz (0.4 kW~15 kW) for 3G3MX2-A4 models !Caution Be sure not to power a three-phase-only inverter with single phase power. Otherwise, there is the possibility of damage to the inverter and the danger of fire. 49 50Step-by-Step Basic Installation Section 2-3 !Caution Be sure not to connect an AC power supply to the output terminals. Other- wise, there is the possibility of damage to the inverter and the danger of injury and/or fire. MX2 Inverter Output to Motor Power Input !Caution Remarks for using ground fault interrupter breakers in the main power supply: Adjustable frequency inverter with integrated CE-filters and shielded (screened) motor cables have a higher leakage current toward earth GND. Especially at the moment of switching ON this can cause an inadvertent trip of ground fault interrupters. Because of the rectifier on the input side of the inverter there is the possibility to stall the switch-off function through small amounts of DC current. Please observe the following: • Use only short time-invariant and pulse current-sensitive ground fault interrupters with higher trigger current. • Other components should be secured with separate ground fault inter- rupters. • Ground fault interrupters in the power input wiring of an inverter are not an absolute protection against electric shock. !Caution Be sure to install a fuse in each phase of the main power supply to the inverter. Otherwise, there is the danger of fire. !Caution For motor leads, ground fault interrupter breakers and electromagnetic con- tactors, be sure to size these components properly (each must have the capacity for rated current and voltage). Otherwise, there is the danger of fire. Step-by-Step Basic Installation Section 2-3 2-3-12 Wire the Inverter Output to Motor Step 4 The process of motor selection is beyond the scope of this manual. However, it must be an AC induction motor with three phases. It should also come with a chassis ground lug. If the motor does not have three power input leads, stop the installation and verify the motor type. Other guidelines for wiring the motor include: • Use an inverter-grade motor for maximum motor life (1600 V insulation). • For standard motors, use the AC reactor accessory if the wiring between the inverter and motor exceeds 10 meters in length. Simply connect the motor to the terminals [U/T1], [V/T2], and [W/T3] as shown in page 46 to page 49. This is a good time to connect the chassis ground lug on the drive as well. The motor chassis ground must also connect to the same point. Use a star ground (single-point) arrangement, and never daisy-chain the grounds (point-to-point). • Check the mechanical integrity of each wire crimp and terminal connec- tion. • Replace the housing partition that covers access to the power connec- tions. Special care to be taken when motor is connected through long wires 2-3-13 Ground Terminal To prevent electric shock, be sure to ground the Inverter and the motor. The 200 V class should be connected to the ground terminal under Class D grounding conditions (conventional Class 3 grounding conditions: 100 Ω or less ground resistance), The 400 V class should be connected to the ground terminal under Class C grounding conditions (conventional special Class 3 grounding conditions: 10 Ω or less ground resistance). For the ground cable, use the compatible cable or a cable with a larger diame- ter. Make the cable length as short as possible. When several Inverters are connected, the ground cable must not be con- nected across several Inverters, and must not be looped. Otherwise, the Inverter and surrounding control machines may malfunction.
