<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.
<2> For p1276 = 300.000 s, the timer is de-activated, i.e. the timer output is always 0. Note: When operating a
motor with a brake, which may not be closed while the motor is rotating, then the monitoring time of both timers
must be set to 300 s.
<3> For operation without brake, p1224[0...3] must be = 0 (factory setting) in order to avoid undesirable interaction
with the sequence control.
<4> Internal signal contains signals that lead to OFF1 or OFF3 such as e.g. BICO or fault response.
