➊
Recommended maximum initial torque setting is 65%.
➋
Recommended maximum soft stop time is 45 seconds.

Soft Stop Time ➋
The Soft Stop function can be
used with applications that
require an extended coast to rest.
When enabled, the voltage ramp
down time can be selected from
0…90 seconds. The motor will
stop when the motor voltage
drops to a point where the load
torque is greater than the motor
torque.

Kick Start
A kickstart, or boost, at the
beginning of the start mode is
intended to provide a current
pulse of 450% of full load
current. The kickstart time is
adjustable from
0.0…1.5 seconds. This allows
the motor to develop additional
torque at start for loads which
may need a boost to get you
started.

SCR Temp Reset Mode
The SMC-3 monitors the SCR
temperature by means of internal
thermistors. When the power
poles maximum rated
temperature is reached, the
microcomputer switches off the
SMC and a Heat Sink
Temperature fault is indicated via
LED.
