L56 Torque Bias (Reference torque end time)
L66 (Unbalanced Load Compensation, Activation time)
L67 (Unbalanced Load Compensation, Holding time)
L56 sets up the reference torque end timer in speed control.
- Data setting range: 0.00 (Disable)
0.01 to 20.00 (s)
In speed control
During the shutdown sequence in speed control, the inverter decreases the reference torque value
held internally to 0, taking time proportional to the value set in L56.
Note that L56 sets the time length required to decrease the motor rated rating torque from 100 to 0%.
