DS6 Soft Start Controllers
DS6 Soft Start Controllers
Product Description
Eaton’s DS6 line of reduced
voltage solid-state soft start
controllers is very compact,
multi-functional, easy to
install, and easy to
commission. Designed to
control the acceleration and
deceleration of three-phase
motors, the device is
available for current ranges
from 40 to 180 amperes.
Application Description
With its small size, it can
easily fit in place of existing
soft starters, wye-delta
starters, or across-the-line
NEMA
This feature allows easy
upgrades to existing
systems. The product is
designed to be wired in the
three-phase line feeding the
three motor input leads as is
done for normal across-the-
line starting. The starter uses
silicon controlled rectifiers
(SCRs) to ramp the voltage to
the motor, providing smooth
acceleration and deceleration
of the load. After the motor is
started, the internal run
bypass contactor closes,
resulting in the motor running
directly across-the-line.
Internal run bypass
significantly reduces the heat
generated as compared to
non-bypass starters. The soft
stop option allows for a ramp
stop time that may be longer
than the coast-to-stop time.
An external over-load
protection is needed.

DS6 Soft Start Controllers
Operation
Voltage Ramp Start
This start method provides a
voltage ramp to the motor,
resulting in a constant torque
increase. This most commonly
used form of soft start mode
allows you to set the initial
voltage value and the
duration of the ramp to
full voltage conditions.
Bypass contactor(s) close
after ramp time has elapsed.

●
Soft Stop
Allows for a controlled
stopping of load. Used when
a stop-time that is greater
than the coast-to-stop time is
desired. Often used with high
friction loads where a sudden
stop may cause system or
product damage. Setting the
soft stop time to a value of
0 turns off this feature.
●
Adjustable initial voltage
30–92% of full voltage
Adjustable ramp time
1–30 seconds
Soft stop time =
0–30 seconds
