This driver has two methods of using low frequency vibration suppression:
(1) Use panel keys to run automatic mechanical resonance suppression enabling selection parameter to
look for suppression frequency
1. Set Pn337 (automatic low frequency suppression delay) to adjust the delay time of automatically
capturing suppression frequency and set Pn338 (low frequency swinging detection level) according
to equipment needs.
2. Set Pn336.0 (automatic mechanical suppression enabling selection)=1~3 and click the “write in”
key to enable automatic detection of low frequency vibration frequency.
3. When finding the low frequency vibration frequency, it will automatically store the low frequency
vibration frequency into the driver parameter and return Pn336.0 to 0 (disable automatic detection
of low frequency vibration frequency). If low frequency vibration frequency cannot be found,
Pn336.0 automatically returns to 0 (disable automatic detection low frequency vibration frequency)
after searching for low frequency vibration frequency for a period of time.
Attention
• If users wish to use automatic low frequency suppression function, the stop time needs to be
1.5 Seconds + time of Pn337.
•
When Pn340, Pn342, Pn344 are set to zero, this indicates the low frequency suppression is
not used.
