– PTC connection type A according to Fig. 6.4
Application
Conveyor belt
Roller conveyor
Compressor
Small fan
Pumps
Hydraulic pump
Stirrers
Milling machines
The motor reaches
its nominal rotational
speed
- with a torque
increase that is too
high
- faster than desired,
with a startup
current that is too
high
1. Switch soft starter
off (IN 1 -> 0).
2. Increase startup
time (turn potentio-
meter clockwise).
3. Reduce current limit
value (turn
potentiometer anti-
clockwise).
Suggested setting
Increase stopping time (turn
potentiometer clockwise)
The motor stops
abruptly and not
softly.
CAUTION
Risk of damage to property!
Connection to an unassigned terminal is not permitted.
Motor:
1. Switch off soft starter
(IN 1 -> 0).
2. Reduce startup time (turn
potentiometer anti-
clockwise).
or
3. Increase limit value if the
current limit is set (turn
potentiometer clockwise).
