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: Sets the smoothing time constant (PT1) for the velocity actual value.
Dependency: Refer to: r0063
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 velocity controller is adapted and/or the velocity
controller settings checked Kp (p1460) and Tn (p1462).
Description: Sets the smoothing time constant (PT1) for the speed actual value.
Dependency: Refer to: r0063
Notice: Smoothing times above 20 ms are only possible if the drive is accelerated or braked with the appropriately long
ramp-up/ramp-down times. Otherwise, significant torque errors can occur and there is the danger that the drive is
powered-down (tripped) with F07902 (motor stalled).
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: Sets the smoothing time for the actual speed value of the speed controller for closed-loop control with encoder.
Note: The smoothing must be increased if there is gear backlash. For longer smoothing times, the integral time of the
speed controller must also be increased (e.g. using p0340 = 4).
Description: Displays the sum of all speed setpoints that are present.
