Power supply
Rated operational power
This motor controller is in-
tended to be used to softstart/
softstop 3-phase squirrel cage
induction motors and thereby
reduce the stress or wear on
gear and belt/chain drives and
to give smooth operation of
machines. Soft starting and/or
stopping is achieved by con-
trolling the motor voltage.
During running operation the
semiconductor is bypassed by
an internal electromechanical
relay.
The initial torque can be ad-
justed from 0 to 85% of the
nominal torque.

The soft-start and soft-stop
time can be adjusted from 0.5
to approx. 7s.

Two yellow LEDs indicate
Ramp up/down and Running
mode.
Overload protection is not pro-
vided in this motor controller
and must therefore be in-
stalled separately.
The controller is switching
2 lines. The 3rd line is continu-
ously connected to the load.
