Edge evaluation: no
Signal state 1 or 611D signals to the PLC that the torque setpoint |M
edge change the steady-state condition (i.e. ramp-up completed) (refer to the diagram).
0 → 1
The threshold torque is set using the machine data:
MD1428 $MD_TORQUE_THRESHOLD_X (threshold torque)
as a % of the actual torque limit value.
The torque threshold characteristic is speed-dependent.
While ramping-up, the interface signal:
DB31, ... DBX94.2 (|M
remains at 1.
The signal |M
DB31, ... DBX94.2 (ramp-up completed) = 1
and the signal interlocking time for the threshold torque:
MD1429 $MD_TORQUE_THRESHOLD_X_DELAY (delay time n
has expired.
Signal state 0 or The torque setpoint |M

If necessary, the PLC user program can initiate a response.
