Product Overview
Control Options
The SMC Dialog Plus controller offers the control options described
below.
Important: The options listed in this section are mutually exclusive
and must be specified when ordering. An existing
controller may be upgraded to another control option by
replacing the control module. Consult your nearest/local
Allen-Bradley sales office.
Soft Stop Option
This option can be used in applications that require an extended coast-
to-rest. The voltage ramp down time is user-adjustable from 0 to 60
seconds and is adjusted independently from the starting time. The
load will stop when the output voltage drops to a point where the load
torque is greater than the developed motor torque.
