Chapter 8 Applied Functions
IN-65~75 Px Define : Although the multi-function input is set at 48 Trq Bias, if the multi-function input is not ON, the Torque
Bias values being input into the keypad, analog or communication are ignored.
CON-60 Trq BiasFF : This is added to the torque bias to compensate for the loss from the motor rotation direction. If a (-)
value is input, the torque bias decreases by the amount of the input.
Permanent Control in Stop : Hold Time
CON-11 Hold Time : Permanent operation continues for the set period of time when the motor decelerates and stops
according to the stop command and the output is blocked.
8.1.14 Torque control (When you want to control torque)
Torque control is controlling the motor for the torque output set at the torque command value.
The rotation speed of the motor stays constant when the output torque and load torque of the motor are in balance.
Therefore, the motor rotation speed in torque control is determined by the load.
If the output torque is larger than the motor load, the motor speed gradually goes up.
To prevent this, it is recommended you set the speed limit to the motor rotation speed.
(You cannot control the torque during limit speed operation)
1) Torque Control Setting
DRV-09 Control Mode should be set as Sensorless or Vector.
- DRV-09 Control Mode : Sets the control mode at No. 3 or 4 SensorlessNo.1,2 or 5 Vector.
- DRV-10 Torque Control : Sets torque control as No. 1 Yes.
