Co: Armature Short-Circuit External State / Easc State - Siemens SINAMICS G150 Manual

If no contactor feedback signal has been selected (p1235), then the system waits for this time before the pulses are
switched in.
Dependency: Refer to: p1230, p1231, p1235, p1236, r1239
Notice: This delay time must be at least long enough so that the contactor contacts reliably open before the pulses are
switched in. The delay time must be greater than the contactor response time. The Motor Module can be damaged if
the delay time is too short.

Note: Activation criterion (one of the following criteria is fulfilled):
- the signal at BI: p1230 (armature short-circuit activation) is 0.
- the drive is not in the state "S4: Operation" or in S5x (refer to function diagram 2610).
- the internal pulse enable is missing (r0046.19 = 0).
Re state "switched out" (r1238 = 0):
- the external armature short-circuit can be selected with p1231 = 1.
Re state "ready" (r1238 = 1):
- as soon as the activation criterion 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
signal "Closed" missing" (r1238 = 4)":
- the control signal to close contactor r1239.0 is set to "1" (closed) and the pulses are suppressed.
- 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 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 transition
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).
