Type S701, Soft Start Controllers with Brake
Type S701, Soft Start Controllers with Brake
Product Description
The S701 soft start
controller with DC injection
brake is designed to control
acceleration and deceleration
of three-phase motors. Brake
current is adjustable from
0–50A DC. The ramp-up
feature is adjustable from
0.5–10 seconds. Torque
adjustment is adjustable
with or without break loose
(kick start) function.

Reduced Voltage Motor Starters
Solid-State Controllers
Application Description
The S701 line of soft start
controllers is specifically
designed to be a low cost
option for soft starting small
(15 hp and down) three-phase
motors. The braking option
is a DC injection system,
allowing for fast stopping of a
three-phase motor. The S701
unit controls current on two
of the three phases to control
the torque being applied to
the motor, allowing for
smooth starting of a motor.
The S701 is designed to be
used with a manual motor
starter or a full voltage
starter. These devices
provide the necessary
overload protection for the
motor and also provide line
isolation for the motor.
Short-circuit protection can
be provided by fuses or
circuit breakers.
