List of Parameters
p1336[0...n]
Slip compensation limit value / Slip comp lim val
Access level: 3
Can be changed: U, T
Units group: -
Min
0.00 [%]
Description:
Sets the limit value for slip compensation in [%] referred to r0330 (motor rated slip).
r1337
CO: Actual slip compensation / Slip comp act val
Access level: 3
Can be changed: -
Units group: -
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]
U/f mode resonance damping gain / Uf Res_damp gain
Access level: 3
Can be changed: U, T
Units group: -
Min
0.00
Description:
Sets the gain for resonance damping for U/f control.
Dependency:
Refer to: p1300, p1339, p1349
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 ... 90 % of the rated motor frequency (p0310), but
up to a maximum of 45 Hz.
For the open-loop control modes p1300 = 5 and 6 (textile sectors), the resonance damping is internally disabled in
order that the output frequency can be precisely set.
p1339[0...n]
U/f mode resonance damping filter time constant / Uf Res_damp T
Access level: 4
Can be changed: U, T
Units group: -
Min
1.00 [ms]
Description:
Sets the filter time constant for resonance damping for U/f control.
Dependency:
Refer to: p1300, p1338, p1349
