Torque reference can be set in the same way as the frequency reference. The torque control mode set, the frequency
reference is not active.
DRV-08 Trq Ref Src : Selects the type to use as the torque reference.
0 : Keypad-1, 1 : keypad-2
Input the torque reference using the keypad. The torque can be set in CON-02 Cmd Torque and up to 180% of the motor
rated torque can be set.
2 : V1, 3 : I1
The torque reference can be input by using the voltage(V1) or current(I1) terminal block of the inverter. Set the maximum
torque by using the item of IN-02 Torque at 100%. For example, if IN-02 is set at 200% and the torque reference is set with
the current input(V1), you can check the setting in MON mode and select no. 19 Torque Ref from CNF-06 ~ 08.
6 : Int 485
Sets the torque limit by using the communication terminal of the inverter terminal block.
3) Speed Limit
Caution
For operation in the torque control mode, the sensorless vector mode and the basic operation
conditions described in the vector control mode should be set in advance.
Torque control is not available during low speed regeneration region and low speed light load. Please,
choose vector control.
When using torque control, do not switch over commands of forward and reverse rotation are during
operation. It may cause over current or deceleration error of reverse way. When controlling with vector
control, please set Speed Search in case that there is possibility to operate during motor free run.
(CON-71 Speed Search = set Speed Search during acceleration(0001)
During operation in the torque control mode, the operating speed can go up at the maximum operating speed
according to the load condition. Therefore the speed limit function is used to prevent such divergence of speed.
