6.6.6. Resonance and vibration suppression filter
The SDE servo drive provides
“auto resonance suppression function”. The relevant parameters
and settings are described in the following table. 3 sets of resonance suppression filter, a low-pass filter
to suppress resonance, in accordance with the needs of the user can manually or automatically
suppressed suppression will be sequentially described.

(1) Resonance suppression
(a) Manual mode
The SDE servo drive provides 3 resonance suppression filters and 1 resonance suppression
low-pass filter. If the resonance frequency of mechanism is known, users can set the filter
frequency and attenuation degree manually. Increase these parameters gradually and observe
the effect until the resonance erased. To eliminate the resonance means the
reduction of
mechanism system bandwidth.
(b) Auto mode
The SDE servo drive provides 2 resonance suppression filters for auto mode. When the
resonance is occurred, user can set PB27 to enable the auto mode. (PB27=1 or PB27=2) In auto
mode, the drive will detect the resonance frequency then will decide the attenuation degree. The
result of auto mode will be stored into PB01/PB02 and PB21/PB22. If PB27 is set as 1 when auto
mode is performed, after the resonance detection, the PB27 will automatically recover to 0. If
PB27 is set as 2, the resonance detection and suppression will always keep going.
After trying auto mode once, if the resonance phenomenon still exists, check the PB02 and
PB22. If one of them is 32, it means the resonance could not be compensated in current
response level. It is recommended to reduce response level then try auto mode again. If one of
