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.

 Parameters 11-16 & 11-17 can be used to enhance the response of the regeneration
prevention control, Excessive adjustment could lead to output frequency instability.
 If decreasing the setting of parameter 11-16 is not correcting the output frequency instability
then try decreasing the parameter 11-17.
