Lenze Choice Info
C079 Oscillation damping Is not transferred when
transferring
parameters via the
822X/824X 5 0 {1} 80
transferring
parameters via the
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.
