4.2 Parameter Settings for Applications

Speed Search
Applications
Windmill, winding
machine, fan and all
inertia loads
DC Brake before Running
Applications
When e.g. windmills,
fans and pumps rotate
freely by wind or flow
without applying power
Energy Saving
Applications
Punching machines
fans, pumps and
precision machinery
Multi-step Operation
Applications
Conveying machinery
Switching acceleration and deceleration times
Applications
Auto turntable for
conveying machinery
4-32
Purpose
Restart free-
running motor
Purpose
Keep the free-
running motor at
standstill.
Purpose
Energy saving and
less vibrations
Purpose
Cyclic operation by
multi-step speeds.
Purpose
Switching
acceleration and
deceleration times
by external signal
Functions
Before the free-running motor is
completely stopped, it can be restarted
without detection of motor speed. The
AC motor drive will auto search motor
speed and will accelerate when its
speed is the same as the motor speed.
Functions
If the running direction of the free-
running motor is not steady, please
execute DC brake before start-up.
Functions
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.
Functions
To control 15-step speeds and duration
by simple contact signals.
Functions
When an AC motor drive drives two or
more motors, it can reach high-speed
but still start and stop smoothly.
