Advanced Stopping Methods
The drive can be selected to NOT FAST STOP or to NOT COAST STOP. The stopping procedure is
unaffected by Local or Remote Sequencing options.
Forced Fast Stop
The Not Fast Stop mode overrides the RUN FORWARD, RUN REVERSE and JOG inputs in Remote
mode, and the RUN and JOG Keypad keys in Local mode.
Select the SETUP::SEQ & REF::REFERENCE STOP::FAST STOP MODE parameter to either RAMP or
COAST. The stopping sequence starts when the NOT FAST STOP input goes FALSE, regardless of the
state of the RUN input.
