<1> Shutdown threshold of the standstill detection. In this case (e.g. when using a brake), another criterion than the
speed actual value can be selected to clear the pulses. Otherwise, we recommend to keep the factory setting.
<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 must not be applied while the motor is rotating, 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> The internal signal comprises signals that lead to OFF1 or OFF3, e.g. BICO or fault response.
<5> Only for SINAMICS S120.
