Parameters
Windmill, winding
machine, fan and all
inertia load
Restart free-
running motor
Before the free-running motor is
completely stopped, it can be restarted
without detecting motor speed. The AC
motor drive will auto search motor
speed and will accelerate when its
speed is the same as the motor speed.

Parameters
Punching machines
and precision
machinery
Energy saving and
less vibrations
Energy saving when the AC motor
drive runs at constant speed, yet full
power acceleration and deceleration
For precision machinery it also helps
to lower vibrations.
