Note: External armature short-circuit (bits 0 ... 3):
Re bit 00:
Using this signal, the motor is short-circuited through an external contactor circuit. This means that this BO: p1239.0
must be interconnected e.g. to a digital output.
Re bit 01:
This signal indicates the state of the contactor to establish the armature short-circuit. To do this, BI: p1235 must be
interconnected to a digital input.
Re bit 02:
The external armature short-circuit configuration is ready and is activated as soon as the activation criterion is
fulfilled.
Re bit 03:
1: A feedback signal from an external contactor was parameterized in BI: p1235.
Internal voltage protection / internal armature short-circuit (bits 4 ... 6):
Re bit 04:
a) Internal voltage protection (p1231 = 3) was selected and the Motor Module does not support the autonomous
internal voltage protection (r0192.10 = 0).
The Control Unit issues the command to the Motor Module to short-circuit the motor through the power
semiconductors.
a) Internal voltage protection (p1231 = 3) was selected and the Motor Module supports the autonomous internal
voltage protection (r0192.10 = 1).
The Motor Module decides autonomously whether the armature short-circuit is activated. In this case, the following
applies: r1239.4 = r1239.5.
c) Internal armature short-circuit (p1231 = 4) was selected.
The Control Unit issues the command to the Motor Module to short-circuit the motor through the power
semiconductors.
Re bit 05:
The Motor Module signals that the motor is short-circuited in the Motor Module through the power semiconductors.
