USER MANUAL

4.7.1.2
Coast to Stop
In this mode the RAMP DECEL RATE ramp and the STOP RATE ramp are both ignored. Thus the SPEED
DEMAND changes immediately to 0% as soon as the Stop command is given. The power stack is also
immediately disabled at this time, causing the load to coast.
4.7.2
ADVANCED STOPPING METHODS
The Inverter can be selected to /FAST STOP or to /COAST STOP. The stopping procedure is unaffected by
Local or Remote Sequencing options.
4.7.2.1
Forced Fast Stop
The /Fast Stop mode overrides the RUN FWD, RUN REV and JOG inputs in Remote mode, and the RUN and
JOG Operator Station keys in Local mode. It is selected by setting /FAST STOP to TRUE.
The Fast Stop mode can be set to either RAMP or COAST. The stopping sequence starts when the /FAST
STOP input goes FALSE, regardless of the state of the RUN input.
4.7.2.2
Forced Coast Stop
Using the /Coast Stop mode immediately disables the power stack, causing the load to coast to a stop. The
Inverter gives priority to the /COAST STOP signal. The /FAST STOP signal is therefore ignored while /COAST
STOP is active.
