Close brake from standstill detection
<2>
For p1276 = 300.000 s the timer is de-activated, i.e. the timer output is always 0.
Note: If a motor is operated with a brake that may not be closed while the motor is rotating, then the monitoring
time of both timers must be set to 300 s.
<1>
Shutdown threshold of the standstill detection. Here (e.g. when using a brake), another criterion to cancel the
pulses can be selected other than the speed actual value. Otherwise, we recommend that the factory setting is
kept.

For operation without brake, p1224[0...3] must be 0 (factory setting) in order to avoid mutual effects with the
sequence control.
