SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 01/2011

Description: Sets the limit value for slip compensation in [%] referred to r0330 (motor rated slip).

Description: Displays the actual compensated slip [%] referred to r0330 (rated motor slip).

Dependency: p1335 > 0 %: Slip compensation active.

Refer to: p1335

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.

Description: Sets the filter time constant for resonance damping for U/f control.

Dependency: Refer to: p1300, p1338, p1349
