5.2 Parameter Settings for Applications

Speed Search
Applications
Windmill, winding
machine, fan and all
inertia load
DC Brake before Running
Applications
When e.g. windmills,
fans and pumps rotate
freely by wind or flow
without applying power
Motor power switch-over between AC motor drive and commercial power
Applications
Windmills, pumps,
extruders
Energy Saving
Applications
Punching machines
and precision
machinery
Multi-step Operation
Applications
Conveying machinery
5-18
Purpose
Restart free-
running motor
Purpose
Keep the free-
running motor at
standstill.
Purpose
Switching motor
power between AC
motor drive and
commercial power
Purpose
Energy saving and
less vibrations
Purpose
Cyclic operation by
multi-step speeds.
Functions
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.
Functions
If the running direction of the free-
running motor is not steady, please
execute DC brake before start-up.
Functions
When switching motor power between
the AC motor drive and commercial
power, it is unnecessary to stop the
motor or start by commercial power
with heavy duty before switching to by
AC motor drive control
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 signal.
