parameters via the
operatingmodule.
Function Suppression of idling oscillations when:
a drive does not match, i.e. rated controllerpower - motor
e.g. operation with high chopper frequency and the related power derating,
operation of higher-pole motors,
operation of specialmotors,
having a resonance phenomenon in the drive set.
Adjustment 1.Approach the area with speed oscillations.
2.Reduce the oscillation bychanging C079 step by step.
- Indicators for smooth running can be a uniform motor current or the reduction of the
mechanical vibrationsinthe bearingseat.
Important
Parameter transfer from C079 not possible via keypad.
Compensate the resonances in speed controlled operation via the parameters of the controller.
