transferring

operating module.

Function

Suppression of idling oscillations when:

-

a drive does not match, i.e. rated controller power - motor
e.g. operation with high chopper frequency and the related power derating,

-

operation of higher-pole motors,

-

operation of special motors,

-

having a resonance phenomenon in the drive set.

Adjustment

1.Approach the area with speed oscillations.
2.Reduce the oscillation by changing C079 step by step.

- Indicators for smooth running can be a uniform motor current or the reduction of the

mechanical vibrations in the bearing seat.

Important

-

Parameter transfer from C079 not possible via keypad.

-

Compensate the resonances in speed controlled operation via the parameters of the controller.
