Mandatory actions for installing and wiring the option include:

• Shut off power when installing and wiring this option.
• Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit. If steps above are not properly performed, this can result in electric shock or product failure.
• Use an emergency stop device and an additional safety device in your system to prevent serious accident due to the option malfunctions. Usage without any emergency stop device or any additional safety device can result in accident or injury.
• Use an additional safety device with your system to prevent a serious accident due to the network malfunctions. Usage without an additional safety device may cause an accident.
• Make sure that the operation signals are STOP before resetting drive’s fault. The motor may suddenly start and that may result in injuries.
• Do not pull on any cable itself. Doing so could result in damage or malfunction.

Prohibited actions include:

• Do not connect to any communication device other than the one supported. It may cause an accident.
• Do not touch the sharp edges of the inverter or option. Doing so could result in injury.
• Do not use application of writing into inverter parameters more than 100,000 times. The Life of EEPROM is approximately 100,000 times. Frequent writing to the EEPROM of inverter will cause a memory corruption.
• Insert an electromagnetic contactor between the inverter and the power supply so that the machine can be stopped without fail from an external controller in case of an emergency.
• Check DeviceNet state (using below attribute) when the option is deactivated by an unusual event such as an operating error, power outage, failure, etc. (Identity Object Instance Attributes 8 (State) – The communication error occurs when Fault (4, 5) or this value cannot be read.) Deactivated option may cause an accident, if the DeviceNet state is not checked.

Notes on use:

• Please install away from the place where temperature and humidity change rapidly.
• Keep a distance of 20cm or more between the drive ‘s power cable and the data transmission cable. Or the drive might malfunction because of noise.
• If the control power is turned off due to momentary power failure etc., communication can not be performed temporarily.

The mounting/removing of the option must be performed without supplying power. Turn off all input power, wait at least 15 minutes, and confirm that the charge lamp of the inverter is no longer lit. The inverter and option can become damaged. Do not use a tool for the mounting/removing of the option. The inverter and option can become damaged.

For how to mount and remove the option for VF-AS3, refer to [Mounting/removing insert type options] of E6582062.

The DeviceNet baud rate setup is controlled by the inverter parameter (200. as shown in the table:

Note: DeviceNet baud rate is 500kbps and with a few slaves in the network, auto baud rate function might not work.

The inverter operation at the communications loss action is set by parameter (101 as follows:

Caution: Please note that the inverter keeps driving when the communication is lost if 1 (None) is set to the parameter (101 (Inverter operation at the communications loss action).

The switching between Local and Remote modes can be controlled via the terminal block function as shown in the example for VF-AS3:

• F terminal: RUN command
• R terminal: DeviceNet /Local (Terminal in this example) switching
• RR terminal: Operation frequency command

• (70d (command mode selection) = 0 (terminal board)
• F708 (frequency setting mode selection 1) = 1 (RR)
• F112 (input terminal selection 2 (R)) = 48 (DeviceNet/Local control)

• R-P24 terminal open: VF-AS3 is controlled as slave device of DeviceNet.
• R-P24 terminal closed:
• F-P24 terminal short to RUN
• F-P24 terminal open to STOP
• Output frequency is set up by the RR signal input.

The inverter parameter access is provided by Class code 0x65 (Attribute ID is 3, inverter parameter number is set as Instance ID).

For example, to set 5 sec. to “Acc. time” (minimum unit 0.1 sec., set value 50 = 0x0032 (Hex.), communication number “0009”): set the value 0x0032 to Class 0x65, Instance 0009, Attribute 3 to use Set Single Attribute service.

Parameter AU I cannot be accessed by using Class 0x65. Please, use Class 0x64.

For Class code 0x64:

• All parameter’s Attribute ID is 3.
• The instance ID should be set “VF-MB1 or VF-S15 parameter communication number + 0x4000”.
• In the case of the parameter from which a communication number begins in “F”, it should be set “the inverter parameter communication number – 0x8000 (same as bit 15 set to 0)”.

Examples for Class 0x64:

• In case of Basic parameter “C70d – Command mode selection”, Communication No: 0003 -> Instance ID: 4003
• In case of Extended parameter “F300 – PWM carrier frequency”, Communication No: 0300 -> Instance ID: 4300
• In case of Monitor parameter “FE03 – Output current”, Communication No: FE03 -> Instance ID: 7E03. Monitor parameter can access “Get” only.

Caution: Do not use application of writing into inverter parameters more than 100,000 times. The Life of EEPROM is approximately 100,000 times. Frequent writing to the EEPROM of inverter will cause a memory corruption.

The Output Instance 102 Layout (Toshiba Specific, parameter (203 = 4) is defined as follows:

The Input Instance 152 Layout (Toshiba Specific, parameter (203 = 4) is defined as follows:

To transmit a command using Output Instance 102:

When you want to set “0xC400″ to parameter FA06, set “1 (FA06)” to parameter C001.

Since 0 and 1 byte of the output instance 102 supports the parameter C001, if “0xC400” is set up here, “0xC400” will be set as FA06.

Example: Command transmitting by the output Instance 102.

The setting “0xC400” is set as the parameter FA06.

To monitor the output current using Input Instance 152:

Set “3 (F803)” to parameter C021.

The value of the parameter F803 specified as 0 and 1 byte of the input instance 152 with the parameter C021 is inputted.

Example: State monitor by the input instance 152.

The value of the parameter Fd03 (ex.0x1234) outputted.

The Output Instance 105 Layout (Toshiba Specific, parameter (203 = 5) is defined as follows:

The Input Instance 155 Layout (Toshiba Specific, parameter (203 = 5) is defined as follows:

The purposes of instances 102/152 (Byte 0 – 11) and 105/155 (Byte 6 – 17) are adjustment by real time command transmission, and the monitor of an operation state by using cyclic communication of DeviceNet.

To set Command mode selection via communication command 1 (FA06) using Output Instance 102:

Set “1 (FA06)” to parameter C001 when you want to set the desired value for FA06. Since bytes 0 and 1 of Output Instance 102 support the parameter C001, setting “0xC400” to these bytes will set FA06 to “0xC400”.

Example of setting FA06 to 0xC400:

For VF-MB1/S15:

For VF-AS3:

Frequency reference is set up by 0.01Hz unit and the hexadecimal number. For example, when “Frequency reference” is set up to 80Hz, since the minimum unit is 0.01Hz, 80/0.01 = 8000 = 0x1F40 (Hex.) is used.

Torque reference is set up by 0.01% unit and the hexadecimal number. For example: when “torque command” is set up to “50%”, since the minimum unit is 0.01%, 50%=50+0.01=5000=1388H is used.

By setting up the data of the bit 0 – 1 of terminal output data (FA50) from communication, setting data (OFF or ON) can be outputted to the output terminal. You must select the functional number 92 – 95 as the selection of the output terminal function parameter before using it.

Note: Set 0 to reserved bit.

The current output frequency is read into 0.01Hz of units and by the hexadecimal number. For example, when the output frequency is 80Hz, 0x1F40 (hexadecimal number) are read.

Since the minimum unit is 0.01%, 0x1F40 (Hex.) = 8000 (Dec.) * 0.01 = 80.00 (Hz).

Also about the following parameters, these are the same as this:

• Fd22 (Feedback value of PID (real time)): Unit: 0.01Hz
• Fd16 (Estimated speed (real time)): Unit: 0.01Hz
• Fd29 (Input power (real time)): Unit: 0.01kW
• F630 (Output power (real time)): Unit: 0.01kW

The output current is read into 0.01% of units and by the hexadecimal number. For example, when the output current of the rated current 4.8A inverter is 50% (2.4A), 0x1388 (hexadecimal number) is read out.

Since the minimum unit is 0.01%, 0x1388 (Hex.) = 5000 (Dec.) * 0.01 = 50 (%).

Also about the following parameters, these are the same as this:

• F805 (Output voltage (real time)): Unit: 0.01% (V)
• F804 (Voltage at DC bus (real time)): Unit: 0.01% (V)
• Fd18 (Torque): Unit: 0.01% (N·m)* (100% means the rated motor torque calculated by the motor constant parameters (F405 – F417))

The operated cumulative time is read by the hexadecimal number. For example, when cumulative operation time is 18 hours, 0x12 (18 hours) is read. 0x12 (Hex.) = 18 (Dec., hour).
