4-81
Example: Regeneration prevention during constant speed.
Example: Regeneration prevention during deceleration.
11-14 Regeneration Prevention Voltage Level
Range
200v: 300.0~400.0 V
400v: 600.0~800.0 V
Regeneration prevention voltage level: if the DC bus voltage level is set too low, then
over-voltage protection will not be reached, but the actual deceleration time will be
extended.
11-15 Regeneration Prevention Frequency Limit
Range 【0.00~15.00】Hz
Sets the regeneration prevention frequency limit.
11-16 Regeneration Prevention Voltage Gain
Range 【0~200】%
11-17 Regeneration Prevention Frequency Gain
Range 【0~200】%
11-16/11-17 represent the effect for regeneration prevention. It will enhance the response of
DC bus voltage variation by enlarging the setting. However, it will lead to instability of output
frequency.
If setting 11-16 to be smaller still can’t suppress the shake, please set 11-17 to be smaller.
