Toshiba VF-A7 instruction manual Preset speed operation

[Set value] : VI/II input

Speed commands are entered by means of external signals (terminal VI: 0 to 10 Vdc

or terminal II: 4 to 20 mAdc).

: RR input

Speeds commands are entered by means of external signals (terminal RR: 0 to 10Vdc).

: RX input

Speed commands are entered by means of external signals (terminal RX: 0 to +/-10 Vdc (+/-5 Vdc).

: RX2 control

Speed commands are entered by means of external signals (terminal RX2 (optional):

0to +/-10 Vdc (+/-5 Vdc)).

: Operating panel input enabled

Frequencies are set by pressing the ▲ ▼ key on the control panel or an extended control panel (optional).

: Binary/BCD input

Speed commands are entered from 12/16-bit binary input(optional) or a BCD (optional).

: Communication common serial option

Speed commands are entered from an RS232C device (optional) or terminal board- equipped RS485 device (optional). → Communication number: FA01

: Communication RS485

Speed commands are entered from the RS485 communication device fitted as standard.

→Communication number: FA00

: Communication add-on module option

Speed commands are entered from the network communication device TOSLINE-F10M or S20 (optional).

: Up-down frequency

Speed commands are entered by means of up-down frequency signals from the terminal board (refer to 7.2).

: Pulse input

Speed commands are entered by means of pulses (optional).

Note) This function and the vector control with sensor cannot be used at the same time.

☆The following communication devices are optionally available.

･RS232C (Type: RS2001Z)

･RS485 (Type: RS4001Z. Up to 64 units can be connected.)

･TOSLINE-F10M/TOSLINE-S20

☆The functions assigned to the following control terminals (contact input: Refer to 7.2.) are always activated regardless of the settings of the control device selection parameter  and the speed command selection parameter .

･Reset terminal (assigned to RES by default, enabled only when the invertor trips)

･Standby terminal (assigned to ST by default)

･Emergency stop terminal

☆Be sure to put the inverter out of operation before changing the control device selection parameter  or the speed command selection parameter , though no change can be made to them if the inverter is in operation.

■Preset speed operation

 : Set this parameter at  (terminal board).

 : Any setting is valid.
