Upon receiving your TOSHIBA VF-SX, perform the following steps:

1. Inspect the device to confirm that no parts have been damaged during transit.

2. Confirm that the model number inscribed on the nameplate is the same as that ordered.

3. If the inverter will not be placed in service immediately, store the device in a dust-free environment. Ensure the room is ventilated with cool, dry air and keep the device in its original packing material whenever possible.

4. If there is any damage upon receipt, contact the dealer and the freight company immediately.

To ensure proper installation of your TOSHIBA VF-SX, follow these environmental guidelines:

1. Confirm that the input power supply is within plus or minus 10 percent of the nominal voltage.

2. Do not install the inverter in places where high temperature or humidity are present, in dusty environments, or in environments contaminated with metal particles or metallic powder.

3. Do not mount the inverter on any device subject to intense vibration.

4. Operate the inverter in an environment between -10 degrees C to 40 degrees C. Ensure there is adequate ventilation on all sides.

5. Do not install the inverter near electrical equipment that may cause malfunctions, such as fluorescent lighting, heat-generating equipment like resistors or heaters, or magnetic contactors without surge suppression devices.

6. Install the inverter only on incombustible subpanels, such as a metal subpanel.

7. Always allow at least 10 centimeters of free space above and below the inverter, and at least 5 centimeters of free space on each side. If more than one inverter is mounted in a row, leave at least 10 centimeters between each drive from side to side.

To remove the lower cover of the TOSHIBA VF-SX, press the lower cover on both sides simultaneously and pull the cover forward.

To install the cover on your TOSHIBA VF-SX, insert the cover clasps in the bottom holes, rotate the top of the lower cover back into position, and gently press the clasps into place.

Follow these steps to remove the touchpad from your TOSHIBA VF-SX:

1. Remove the lower cover.

2. Turn the screw at the bottom of the panel completely to the right until it is loose.

3. Pull up gently on the touchpad and lift it off the main body of the drive.

Observe these precautions when wiring the TOSHIBA VF-SX:

1. Always turn the main line power OFF and confirm there is no voltage present before connecting power, motor leads, or control wires.

2. Wait until the CHARGE lamp on the TOSHIBA VF-SX has turned off before working on the drive, as internal capacitors store electrical charge.

3. Do not wire input power to the output terminals (U, V, W) of the TOSHIBA VF-SX, as this will damage the drive.

4. Install a surge suppressor on any electromagnetic coil on any contactor wired to the drive.

5. Use shielded wire or twisted pair wire for control circuit wiring and keep it isolated from power wiring.

6. Do not install a power factor improvement capacitor on the input or output of the TOSHIBA VF-SX.

For the TOSHIBA VF-SX, use the following wire sizes:

For wire to an ammeter, wire to a frequency meter, and wire carrying input speed reference signals, use at least 16 gauge shielded wire.

For all other control wiring, use at least 12 gauge PVC coated wire.

You can set the command mode for your TOSHIBA VF-SX using the Command Mode Selection parameter [C n o d] in the terminal selection parameter group [G r. S t]. The available values are:

A display of O P on your TOSHIBA VF-SX indicates an overvoltage trip on the DC bus. You should check the power source for voltage surges or high voltage.

A display of O H on your TOSHIBA VF-SX indicates an inverter overheating trip. You should check that the cooling fan is operating (on models 2 HP and larger), ensure the ambient temperature is not too high, remove the caution label from the top cover if the ambient temperature is high, and provide more space around the sides of the drive and near the heat sinks.

If the motor connected to your TOSHIBA VF-SX is rotating backwards, reverse the wiring at the output terminals U, V, and W by swapping any two of the wires.

The [C F] parameter on the TOSHIBA VF-SX controls the PWM carrier frequency, which can be adjusted between 0.5 kHz and 3 kHz to manage acoustic motor noise.

Perform a periodic inspection on your TOSHIBA VF-SX every three to six months. Procedures include:

1. Checking all control and power terminals for loose connections.

2. Checking that terminal pressure crimp devices are not damaged, bent, or overheated.

3. Visually inspecting all wiring for insulation integrity.

4. Cleaning all dirt and dust from the drive, especially the cooling vents, using a vacuum cleaner.

5. Measuring input and output voltages during normal operating conditions.

To store your TOSHIBA VF-SX, avoid hot, humid, or dusty areas, or locations contaminated with metallic particles. Do not remove the anti-static shielding bag. For long-term storage, it is recommended to apply power to charge the electrolytic capacitor once per year; contact the factory for the specific procedure to avoid damaging the capacitor.

The TOSHIBA VF-SX provides several control terminals. Terminal F is for forward run, R is for reverse run, ST is for standby/run signal, and CC is the common for control circuits. Other terminals include SS1, SS2/JOG, and SS3/EX, which can be assigned various functions based on your setup.

While in Monitor Mode on your TOSHIBA VF-SX, you can use the up and down arrow keys to scroll through monitored values. The version number of the software on the drive CPU is displayed as U120, and the version of the EEPROM is displayed as UE0.

Use the [P O U t] parameter on your TOSHIBA VF-SX to reduce the output voltage proportionally to the input voltage. If you set the Power Voltage Compensation [P A d J] to 1, you can set the absolute output voltage between 0 and 120%.

Yes, your TOSHIBA VF-SX can automatically switch between acceleration/deceleration times 1 and 2 by setting the [A d 2] parameter to 2 and setting the [A d 2 F] parameter to the desired frequency threshold.

The TOSHIBA VF-SX control panel features lights for Hz, SEC, and %. These indicators show the unit of the data on the 7-segment display. The PANEL CONTROL light indicates that the drive is currently being operated by the touchpad.

The [S F C] parameter on the TOSHIBA VF-SX enables slip frequency compensation to maintain a constant motor speed even when load fluctuations occur. Set it to 1 to activate compensation.

The [S F r] parameter on the TOSHIBA VF-SX is used to enter the motor’s rated slip frequency, which is necessary for accurate slip frequency compensation.

In Monitor Mode on the TOSHIBA VF-SX, you can view the four most recent trips by scrolling with the arrow keys. Each entry shows the trip code, and if you press the MON key, you can view additional data recorded during the trip, such as operating frequency, input voltage, and load current.

When the Parameter Setting Disable Function [P n o d] is set to 0 on your TOSHIBA VF-SX, all attempts to change parameters are disabled, providing a security lock for the drive settings.

To enable multi-speed operation on your TOSHIBA VF-SX, set the [S r. n] parameter to 1. Then, wire the SS1, SS2, and SS3 terminals to common (CC) and configure the frequencies for each speed using the [S r 1] through [S r 7] parameters.

Yes, the TOSHIBA VF-SX provides a fault relay (FL) with terminals FLA, FLB, and FLC. This relay changes state when the drive trips, allowing you to trigger an external alarm or control circuit.

The [F H Y S] parameter on the TOSHIBA VF-SX provides hysteresis for the operation starting frequency, preventing the drive from toggling ON and OFF when a remote control signal is oscillating near the starting frequency.

The [l u l n] parameter on the TOSHIBA VF-SX enables or disables the IV terminal input. This is used in conjunction with the J1/J2 jumpers on the PCB to define how the drive responds to different types of external frequency reference signals.

On your TOSHIBA VF-SX, you can define the IV input characteristics by using two points: [P 1] with output frequency [F-P 1], and [P 2] with output frequency [F-P 2]. These set the input signal percentages and the corresponding desired output frequencies.

The [t r c L] parameter on the TOSHIBA VF-SX determines if the trip status is stored in memory when power is turned off. Setting it to 1 retains the trip information for troubleshooting after a power cycle.

Use the [r r-b] parameter on your TOSHIBA VF-SX to adjust the bias for the RR terminal frequency reference signal, ensuring the desired output frequency matches your input signal.

Use the [r r-G] parameter on your TOSHIBA VF-SX to adjust the gain for the RR terminal, which determines the maximum frequency reached at the maximum input voltage.

The operating ambient temperature for the TOSHIBA VF-SX is -10 to +40 degrees Celsius. Note that this limit can be increased to 50 degrees Celsius if the caution plate is removed.

Yes, you can connect an optional external braking resistor to the PA and PB terminals of the TOSHIBA VF-SX for applications requiring rapid deceleration of high inertia loads.

The [L F H L] parameter on the TOSHIBA VF-SX determines the logic for the low-speed output signal. Setting it to 0 or 1 switches the open-collector output state (ON or OFF) when the output frequency is below the low-speed frequency [L F].
