p1335[0...n] Slip compensation scaling / Slip comp scal
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.0 [%]
Description: Sets the setpoint for slip compensation in [%] referred to r0330 (motor rated slip).
p1335 = 0.0 %: Slip compensation de-activated.
p1335 = 100.0 %: The slip is completely compensated.
Dependency: Prerequisite for a precise slip compensation for p1335 = 100 % are the precise motor parameters (p0350 ... p0360).
If the parameters are not precisely known, a precise compensation can be achieved by varying p1335.
For U/f control types with Eco optimization (4 and 7), the slip compensation must be activated in order to guarantee
correct operation.
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note: The purpose of slip compensation is to maintain a constant motor speed regardless of the applied load. The fact that
the motor speed decreases with increasing load is a typical characteristic of induction motors.
For synchronous motors, this effect does not occur and the parameter has no effect in this case.
For the open-loop control modes p1300 = 5 and 6 (textile sector), the slip compensation is internally disabled in order
to be able to precisely set the output frequency.
If p1335 is changed during commissioning (p0010 > 0), then it is possible that the old value will no longer be able to
be set. The reason for this is that the dynamic limits of p1335 have been changed by a parameter that was set when
the drive was commissioned (e.g. p0300).
p1336[0...n] Slip compensation limit value / Slip comp lim val
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.00 [%]
Description: Sets the limit value for slip compensation in [%] referred to r0330 (motor rated slip).

Refer to: p1335
p1338[0...n] U/f mode resonance damping gain / Uf Res_damp gain
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.00
Description: Sets the gain for resonance damping for U/f control.
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Refer to: p1300, p1339, p1349
