Re state "prompt to remove the armature short-circuit" (r1238 = 5):
- the activation criterion is no longer fulfilled. An attempt is made to again remove the armature short circuit.
- the control signal to close the contactor r1239.0 is set to "0" (open) and the pulses remain suppressed.
- if a contactor feedback signal is not connected (BI: p1235 = 0 signal), the system waits for the delay time (p1237)
to expire until a transition is made into state 1.
- if a contactor feedback signal is connected, the system waits until the feedback signal at BI:p1235 goes to "0"
(open) until a transition is made into state 1. If this does not occur within the monitoring time (p1236), then a transi-
tion is made into state 6.
Re state "active - feedback signal "Open" missing" (r1238 = 6):
- this error state can be exited by de-selecting the external armature short-circuit (p1231 = 0).

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 ful-
filled.
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 semicon-
ductors.
a) Internal voltage protection (p1231 = 3) was selected and the Motor Module supports the autonomous internal
voltage protection (r0192.10 = 1).
