Using Line Voltage to
Control S701
When the contactor C1 is
switched to the ON state, the
motor controller will soft start
the motor according to the set-
tings of the ramp-up time and
initial torque adjustments.
When the contactor C1 is
switched to the OFF state, the
motor will be switched off
instantaneously.
In this application, the contac-
tor will have no load during
making operation.
The contactor will carry and
break the nominal motor cur-
rent. Maximum voltage in this
application is 300V AC.
Separate Input Signal to
S701
When the control input is
switched to the ON state
(S closed), the motor control-
ler will soft start the motor
according to the settings of the
ramp-up time and initial torque
adjustments.
When the control input is
switched to the OFF state
(S open), the motor will be
switched off instantaneously
only if the ramp-down time is
adjusted to 0.
With any other setting, the
motor will be soft stopped
according to the settings of the
ramp-down time adjustment.
Soft Reversing of
Motors up to 5 hp/4 kW
A soft reversing of a motor can
easily be achieved by con-
necting a reversing relay to
the soft starter.
The reversing contactor type
S511 will determine the direc-
tion of rotation forward or
reverse and the soft start type
S701 will perform soft-starting
and soft-stopping of the motor.
If soft stop is not required, the
application can be simplified
by connecting the control cir-
cuit of the soft start controller
to the main terminals as
shown in Figure 6. A delay of
approximately 0.5 seconds
between forward and reverse
control signal must be

Reversing of Motors
Up to 15 hp/11 kW
A soft-reversing of motors can
easily be achieved when the
motor load exceeds 5 hp/4 kW
by connecting a mechanical
reversing contactor to the soft
start controller.
The reversing contactor will
determine the direction of
rotation forward or reverse
and the soft start type S701
will perform soft-starting and
soft-stopping of the motor.
Overload Protection with
Manual Starter
Overload protection of the
motor is easily achieved by
installing a manual motor
starter on the supply side of
the motor.
The manual motor starter pro-
vides means for padlocking
and the necessary clearance
for use as a circuit isolator
according to EN60204-1.
Adjust the current on the man-
ual motor starter according to
the rated nominal current of
the motor.
Overload Protection with
Mechanical Starter
Overload protection of the
motor is easily achieved by
installing a mechanical starter
on the supply side of the soft
start controller.
The overload provides the
necessary motor protection for
an overload condition.
A short circuit protective
device is required to meet UL
requirements.
