DB31, ...
DBX92.1 Rampfunction generator fast stop active
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
PLC receives the signal that the ramp function generator fast stop is active.
The function has been activated by the interface signal:
DB31, ... DBX20.1 (ramp-function generator fast stop)
The drive is stopped without a ramp function with speed setpoint = 0 and without pulse
suppression.
Signal state 0 or
edge change
1 → 0
Ramp function generator fast stop is not active for the drive.
Signal irrelevant for

DBX92.2 Torque limit 2 active
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
Drive (611D) sends an acknowledgment to the PLC that torque limit 2 is active in addition to torque
limit 1. The particular limit value is defined using the drive parameters.
Signal state 0 or
edge change
1 → 0
Only torque limit 1 is active.
