This function code specifies the lower limit of DC bus voltage when the driver operates normally.
Notice
:
When the network voltage is low, the output torque of motor will decrease. In conditions of constant power load and
constant torque load, the low network voltage will increase the input an output current of VFD, so as to lower the
reliability of VFD operation. Therefore the VFD need to run in derated capacity when the network voltage is quite low for
long term.

Depending
on model
During decelerating, the larger of this value, the stronger of the overvoltage suppressing ability.

Depending
on model
This parameter defines auto current limiting threshold, and the set value is the percentage relative to the rated current of
VFD.
