FU1-51~52: Energy Save, Energy Save Level
This function is used to reduce the output voltage in
applications that do not require high torque and
current at its steady speed. The inverter reduces its
output voltage after accelerating to the reference
frequency (steady speed) if the energy save level is
set at 20%. This function may cause over-current trip
due to the lack of output torque in a fluctuating load.
When Energy Save is ON, it may take longer during
deceleration to stop.
