DBX94.2 Run-up completed
Edge evaluation: No
Signal state 1 The actual speed value has reached the speed tolerance band specified via p2164 after a new speed
setpoint specification and has not left the band for the duration of p2166.
Any subsequent speed fluctuations, also outside the tolerance band, e.g. due to load changes, will
not affect the interface signal.
Signal state 0 The run-up procedure is still active after the speed setpoint has been changed.

DBX94.3 |M
Edge evaluation: No
Signal state 1 The current torque utilization is below the torque utilization threshold (torque threshold 2, p2194).
The run-up procedure is completed, the drive is in the steady state and the torque setpoint |M
does not exceed the threshold torque M
The torque threshold characteristic is speed-dependent.
During the run-up, DB31, ... DBX94.3 (|M
run-up has been completed (DB31, ... DBX94.2 == 1) and the signal interlocking time for the threshold
torque has expired.

A motor overload can be determined via the interface signal. An appropriate response can then be
initiated in the PLC user program.
