Ramp-function generator fast stop
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
A fast stop is triggered by the PLC for the drive (611D). Speed setpoint 0 is therefore entered. The
drive is stopped without a ramp function (regenerative braking).
As soon as the fast stop is recognized by the drive module, the interface signal:
DB31, ... DBX92.1 (Ramp-function generator fast stop active) is returned to the PLC.
