Semiconductor Data

This motor controller is in­tended 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 con­trolling the motor voltage.
During running operation the
semiconductor is bypassed by
an internal electromechanical
relay.

The initial torque can be ad­justed from 0 to 85% of the
nominal torque.

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

A green LED indicates supply.
Two yellow LEDs indicate
Ramp up/down and Running
mode.

Overload protection is not pro­vided in this motor controller
and must therefore be in­stalled separately.

The controller is switching
2 lines. The 3rd line is continu­ously connected to the load.

Changing from Direct ON
Line start to soft start
(Line controlled soft-start)

(Fig. 1 & Fig. 2)
Changing a Direct On Line start
into a soft start is very simple
with the RSE soft-starting re­lay:

1) Cut the cable to the motor
and insert the RSE relay.

2) Connect control input to two
of the incoming lines.

Set

initial torque to minimum

and
ramp up and down to maxi­mum.

3) Power up again - adjust the
start torque so the motor
starts turning immediately
after power is applied, and
adjust ramp time to the
appropriate value.

When C1 is operated, the
motor controller will perform
soft-start of the motor. When
C1 is switched off, the motor
will stop, the motor controller
will reset and after 0.5 s a new
soft-start can be performed.

Please note that the controller
does not insulate the motor
from the mains. Contactor C1
is therefore needed as a ser­vice switch for the motor.

Soft-start and soft-stop

(Fig. 3)
When S1 is closed, soft-start
of the motor will be performed
according to the setting of the
ramp-up potentiometer and
the setting of the initial torque
potentiometer. When S1 is
opened, soft-stop will be per­formed according to the set­ting of the ramp-down
potentiometer.

Time between rampings

To prevent the semiconduc­tors from overheating, a cer­tain time between ramping
should be allowed. The time
between rampings depends
on the motor current during
ramping and ramp time (see
tables below).

Fusing Considerations

The motor controller provides
by-passing of the semicon­ductors during running opera­tion. Therefore the semicon­ductors can only be damaged
by short-circuit currents dur­ing ramp-up and ramp-down
function.

A 3-phase induction motor
with correctly installed and
adjusted overload protection
does not short totally between
lines or directly to earth as
some other types of loads,
e.g. heater bands. In a failing
motor there will always be
some part of a winding to limit

the fault current. If the motor
is installed in an environment
where the supply to the motor
cannot be damaged, the short
circuit protection can be con­sidered to be acceptable if the
controller is protected by a 3­pole thermal-magnetic over­load relay (see table below).

If the risk of short circuit of the
motor cable, the controller or
the load exists, then the con­troller must be protected by
ultrafast fuses, e.g. for a 3 A
type: Ferraz 6.9 gRB 10-10,
for an 12 A type: Ferraz 6.9
gRB 10-25. Fuseholder type
CMS10 1P.

Note:

Table is valid for ambient
temperature 25°C. For higher
ambient temperature add
5%/°C to values in the tables.
The shaded areas in the ta­bles are for blocked rotor. Do
not repeat rampings with
blocked rotor.
