11- 14 Regeneration Prevention Voltage Level
Range
【200V:300.0~400.0, 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.

Regeneration avoidance function response can be improved by increasing 11-16/11-17. This will
improve the response to voltage changes on the DC bus, but may cause output frequency
instability.Set 11-16 as low as possible to reduce output frequency instability if this does not correct
the instability then reduce the setting of parameter 11-17.
Set 11-16 as low as possible to reduce the output frequency instability. If this does not correct the
instability then reduce the setting of parameter 11-17, and re-adjust 11-16.

Set motor rated RPM in this parameter if required then the display will show this value when inverter
output frequency reaches the motor name plate frequency. 50Hz or 60 Hz as appropriate.
The line speed display is linearly proportional to the output frequency 0 to 50Hz or 0-60 Hz as
