FUN-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
when running at steady speed. The drive will reduce its
output voltage after accelerating to the reference
frequency (steady speed) if the energy save level is set
at a non-zero value.
CAUTION
This function may cause over-current trips to
occur due to the lack of output torque when used
on a fluctuating load. If the manual energy saver
value is reduced too much, the applied motor
voltage may be too low for correct motor
operation and motor stalling and/or overheating
may result.
Note: When Energy Save is ON, it may take longer
to decelerate to a stop.
