Name Description Default
Modify
constant bus voltage control method, which
makes the motor
in power generation state. The
regenerative power can maintain the bus voltage
to ensure normal running of the VFD until the
recovery of power.

Note:

This function can avoid VFD stop that is made
for the purpose of protection in grid switchover.

This function can be enabled only when the
input phase loss protection function is disabled.

DC bus voltage V
If the bus voltage exceeds the overvoltage
stalling
protection point, the motor is in power
generation state, and the overvoltage stalling
protection function takes effect to regulate output
frequency (that is, consume unnecessary
regenerative electricity).
