Speed-dependent Kp_n/Tn_n adaptation
● p1460[0...n] Speed controller P gain lower adaptation speed
● p1461[0...n] Speed controller Kp adaptation speed upper scaling
● p1462[0...n] Speed controller integral time lower adaptation speed
● p1463[0...n] Speed controller Tn adaptation speed upper scaling
● p1464[0...n] Speed controller lower adaptation speed
● p1465[0...n] Speed controller upper adaptation speed
● p1466[0...n] CI: Speed controller P gain scaling
3.4 Torque-controlled operation
Description
An operating mode switchover (p1300) can be carried out or a binector input (p1501) used to
switch from speed control to torque control mode. All torque setpoints from the speed control
system are rendered inactive. The setpoints for torque control mode are selected by
parameterization.
Properties
● Switchover to torque control mode via:
● Torque setpoint can be specified:
● Display of the overall torque
Commissioning of torque control mode
1. Set torque control mode (p1300 = 23; p1501 = "1" signal)
2. Specify torque setpoint
