Description: Sets the smoothing time constant (PT1) for the speed actual value.
Dependency: Refer to: r0063, p1451
Note: The speed actual value should be smoothed for encoders with a low pulse number or for resolvers.
After this parameter has been changed, we recommend that the speed controller is adapted and/or the speed con-
troller settings checked Kp (p1460) and Tn (p1462).
Description: Displays the sum of all speed setpoints that are present.
The following sources are available for the displayed setpoint:
- setpoint at the ramp-function generator input (r1119).
- speed setpoint 1 (p1155).
- speed setpoint 2 (p1160).
- speed setpoint for the speed pre-control (p1430).
- setpoint from DSC (for DSC active).
- setpoint via PC (for master control active).
Dependency: Refer to: r1119, p1155, p1160, p1430
Description: Sets the smoothing time for the calculated speed actual value in sensorless operation.
Dependency: Refer to: p1441
Description: Displays the system deviation of the I component of the speed controller.
When the reference model is inactive (p1433 = 0 Hz), this parameter corresponds to the system deviation of the
complete PI controller (r1454 = r0064).
