Re state "ready" (r1238 = 1):
- as soon as the activation criteria is fulfilled, then a transition is made into the state "active" (r1238 = 2).
Regarding the state "active" (r1238 = 2), "active - feedback signal "Closed" OK" (r1238 = 3)", "active - feedback sig-
nal "Closed" missing" (r1238 = 4)":
- the control signal to close contactor r1239.0 is set to "1" (closed) and the pulses are canceled.
- if a contactor feedback signal is not connected (BI: p1235 = 0 signal), then a transition is immediately made into
state 3.
- if a contactor feedback signal is connected, then a transition is made into state 3 if the feedback signal at BI:
p1235 goes to "1" (closed) within the monitoring time (p1236).
- otherwise, a transition is made into state 4.
Re state "prompt to remove the armature short-circuit" (r1238 = 5):
- the activation criteria 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 canceled.
- 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).
Description: Displays the status word for armature short-circuit.
Dependency: Refer to: p1230, p1231, p1232, p1233, p1234, p1235, p1236, p1237
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 criteria 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):
r1239.0...10 CO/BO: Armature short-circuit / DC brake status word / ASC ZSW
