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.
p1336[0...n] Slip compensation limit value / Slip comp lim val
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: V/f control
Min
0.00 [%]
Description: Sets the limit value for slip compensation in [%] referred to r0330 (motor rated slip).
r1337 Actual slip compensation / Slip comp act.val.
VECTOR Can be changed: -
Data type: Floating Point
P-Group: V/f control
Min
- [%]
Description: Displays the actual compensated slip [%] referred to r0330 (rated motor slip).
Dependency: p1335 > 0 %: Slip compensation active.
Refer to: p1335
p1338[0...n] V/f mode resonance damping gain / Uf Res_damp gain
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: V/f control
Min
0.00
Description: Sets the controller gain for resonance damping for V/f control.
Dependency: Refer to: p1300, p1339
Note: The resonance damping function dampens active current oscillations that frequency occur under no-load condi-
tions.
The resonance damping is active in a range of approximately 5 ... 70 % of the rated motor frequency (p0310).
p1339[0...n] V/f mode resonance damping filter time constant / Uf Res_damp T
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: V/f control
Min
1.00 [ms]
Description: Sets the filter time constant of the controller for resonance damping with V/f control.
Dependency: Refer to: p1300, p1338
