DBX20.0
Rampup times
Edge evaluation: no
Signal state 1 or V/f operation operation is activated using machine data:
edge change MD1014 $MD_U/F_MODE_ENABLE.
0 → 1
The time entered in the machine data:
MD1126 $MD_U/F_MODE_RAMP_TIME_2
is effective.
Signal state 0 or V/f operation operation is activated using machine data:
edge change MD1014 $MD_U/F_MODE_ENABLE.
1 → 0
The time entered in the machine data:
MD1125 $MD_U/F_MODE_RAMP_TIME_1
is effective.

DBX20.1 Rampfunction generator fast stop
Edge evaluation: no
Signal state 1 or A fast stop is triggered by the PLC for the drive (611D). Speed setpoint 0 is therefore entered. The
edge change drive is stopped without a ramp function (regenerative braking).
0 → 1
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.
Signal state 0 or No rapid stop is requested by the PLC for the drive.
