Do not use application of writing into inverter parameters more than 100,000 times for the TOSHIBA TOSVERT VF-AS3. The Life of EEPROM is approximately 100,000 times. Frequent writing to the EEPROM of inverter will cause a memory corruption.

The following steps must be performed before wiring and installation for the TOSHIBA TOSVERT VF-AS3:

Turn off all input power, wait at least 15 minutes, and confirm that the charge lamp of the drive is no longer lit.

If steps above are not properly performed, this can result in electric shock.

Use an emergency stop device and an additional safety device in your system to prevent serious accident due to the option malfunctions of the TOSHIBA TOSVERT VF-AS3.

Usage without any emergency stop device or any additional safety device can result in accident or injury.

Do not connect RS485 communication cable into Ethernet port on the TOSHIBA TOSVERT VF-AS3. Erroneous connection will result in failure.

To access the Embedded Ethernet setting screen of the guidance function on the TOSHIBA TOSVERT VF-AS3 LCD panel, follow this operation:

[ESC] key => Select “3. Guidance function” => [OK] key => Select “3.1 Embedded Ethernet” => [OK] key

The Embedded Ethernet setting screen on the TOSHIBA TOSVERT VF-AS3 allows you to set IP address setting mode, IP address, subnet mask, default gateway and device name. In addition, you can check the currently settings in the monitor display by scrolling the screen.

When transmitting frequency command or output frequency, data is converted using [FH: Maximum frequency] on the TOSHIBA TOSVERT VF-AS3 as below:

f_c (%) = (Leader frequency value(Hz) × 10000) / (Leader maximum frequency(Hz) * (1=0.01%))

Calculation results of 1 (0.01%) or less are rounded down. As a result, a maximum error of 0.01% occurs.

The conversion details of frequency commands after they are received by followers on the TOSHIBA TOSVERT VF-AS3 result in the value written to the RAM as a frequency command value:

f_c (Hz) = (Reception data(%) × Follower maximum frequency(Hz)) / 10000 (1=0.01Hz)

Calculation results of 1 (0.01 Hz) or less are rounded down. As a result, a maximum error of 0.01 Hz occurs.

The details for the bits in [FA36: Communication command1 from embedded ethernet] on the TOSHIBA TOSVERT VF-AS3 are:

*1 When set “12 [Sr0]” to FMOd, preset speed operation frequency 0 is selected.

*2 The V/f switching ORs with Bit 10 of [FA38].

*3 The Acc/Dec switching ORs with Bit 8 of [FA38].

*4 When set “2 [Embedded Ethernet]” to CMOd, the Bit 11 (Coast stop) of [FA36] is ON at startup. If you want to start the operation by [FA36], please turn OFF the Bit 11.

The details for the bits in [FA38: Communication command 2 from embedded ethernet] on the TOSHIBA TOSVERT VF-AS3 are:

*1 The Acc/Dec switching ORs with Bit 6 of [FA36]. When changing Acc/Dec in four types, set Bit 6 of [FA36] to “0” and use [FA38].

The frequency command on the TOSHIBA TOSVERT VF-AS3 is set up by 0.01Hz unit and the hexadecimal number. For example, when “Frequency command” is set up to “80Hz”, since the minimum unit is 0.01Hz, 80Hz=80÷0.01 = 8000 (Dec.) = 0x1F40 (Hex.).

This frequency command value is enabled only when the frequency command via embedded ethernet is enabled. To make frequency commands via embedded ethernet enabled, set [FMOd: Frequency command select 1] to “20”: Embedded Ethernet” or set the “Command priority” option (bit 14 of [FA36]).

The torque reference on the TOSHIBA TOSVERT VF-AS3 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 (Dec.) =0x1388 (Hex.).

– [FD30: Output power] ……………………………………………………… Unit: 0.01kW

The output current on the TOSHIBA TOSVERT VF-AS3 is read into 0.01% of units and by the hexadecimal number. For example, when the output current is 2.4A with the rated current 4.8A, 0x1388 (50.00%) 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:

– [FD04: Input voltage (DC detection)] …………………………………. Unit: 0.01% (V)

– [FD05: Output voltage]…………………………………………………….. Unit: 0.01% (V)

– [FD18: Torque] ……………………………………………………………….. Unit: 0.01% (Nm)*

[FE35: Terminal RR input value], [FE36: Terminal RX input value], and [FE37: Terminal II input value] on the TOSHIBA TOSVERT VF-AS3 can be used as A/D converter.

[FE35] and [FE37] are capable of reading the data from external devices in a range of 0.01 to 100.00% (unsigned data: 0x0000 to 0x2710).

[FE36] is capable of reading the data from external devices in a range of -100.00 to 100.00% (signed data: 0xD8F0 to 0x2710).

If analog input mode is selected with the frequency setting mode selection parameter, however, keep in mind that any data entered via an analog terminal is regarded as a frequency command.

The operated cumulative time on the TOSHIBA TOSVERT VF-AS3 is read by the hexadecimal number from [FE14: Cumulative run time for monitor]. For example, when cumulative operation time is 18 hours, 0x12 (18 hours) is read. 0x12 (Hex.) = 18 (Dec., hour).

The output value of FM terminal or AM terminal read from [FE40: FM output monitor] and [FE41: AM output monitor] on the TOSHIBA TOSVERT VF-AS3 is set to 0 to 10000 (0x2710).

Note)

The IO Scanning service on the TOSHIBA TOSVERT VF-AS3 is used to exchange I/O data between a controller (PLC) and the inverter. It is usually performed by implicit services, thus avoiding the need to program the controller (PLC).

The IO Scanning service operates if it has been enabled in the PLC with function code 0x17.

When you use the I/O scanning service, set the “255” (0xFF) to the Unit ID.

Time out detection time of IO scanning service can be changed by parameter [C666: Emb Eth. I/O scan timeout detection time].

Up to ten of the Read/Write register data will be exchanged by the I/O scan services using Modbus function code 0x17 on the TOSHIBA TOSVERT VF-AS3. By parameter setting of [C641] – [C650], [C651] – [C660], you can assign command / monitor parameters for each register. Since the No. 0 of register is in the reservation data, please use the register No. 1 to No. 10.

If the following errors occur, the reply command from the inverter is returned by adding 80H to the command received by the inverter for the Modbus function code 43 (0x2B) Read Device identification on the TOSHIBA TOSVERT VF-AS3. The error codes are as follows:
