8.12.2.7 Actual value monitoring
If an actual value monitoring time > 0 s is selected in C02593/1, the actual speed time
monitoring is active.
 The monitoring time starts when the speed setpoint has reached the lower switching
threshold and the actual speed is still above this threshold. (see illustration
chapter
 If the actual speed is still above the threshold when the monitoring time has expired,
the brake will be automatically applied in the automatic brake control mode (mode 12).

Note!
In the Lenze setting, the actual speed time monitoring is deactivated
