drive is recognized. This percentage parameter value is relative to the set
The switch-off threshold is to be adjusted according to the load behavior of the drive and the device
output, as the drive must be controlled to a speed below the switch-off threshold.

637 Switch-Off Threshold Stop Function
WARNING
If the motor builds up a stopping torque, it may be possible that the switch-off thresh-
old stop function is not reached due to the slip frequency and the standstill of the drive
is not recognized. In this case, increase the value of the
