Coast to Stop
Set the SETUP::SEQ & REF::REFERENCE STOP::RUN STOP MODE parameter to COAST.
In this mode the DECEL TIME ramp and the STOP TIME 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.
