Decelerate
to a stop
Decelerates the pulse output
to a stop.
If ACC(888) started the opera-
tion, the original accelera-
tion/deceleration rate will
remain in effect.
If SPED(885) started the oper-
ation, the acceleration/deceler-
ation rate will be invalid and
the pulse output will stop
immediately.
