207904 <location>External armature short-circuit: Contactor feedback signal
"Closed" missing
Message -
value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: When closing, the contactor feedback signal (p1235) did not issue the signal "Closed" (r1239.1 = 1)
within the monitoring time (p1236).
Remedy: - check that the contactor feedback signal is correctly connected (p1235).
- check the logic of the contactor feedback signal (r1239.1 = 1: "Closed", r1239.1 = 0: "Open").
- increase the monitoring time (p1236).
- if required, set the external armature short-circuit without contactor feedback signal (p1231=2).
207905 <location>External armature short-circuit: Contactor feedback signal
"Open" missing
Message -
value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: When opening, the contactor feedback signal (p1235) did not issue the signal "Open" (r1239.1 = 0)
within the monitoring time (p1236).
Remedy: - check that the contactor feedback signal is correctly connected (p1235).
- check the logic of the contactor feedback signal (r1239.1 = 1: "Closed", r1239.1 = 0: "Open").
- increase the monitoring time (p1236).
- if required, set the external armature short-circuit without contactor feedback signal (p1231=2).
207906 <location>Armature short-circuit / internal voltage protection:
Parameterization error
Message Fault cause: %1, motor data set: %2
value:
Drive object: SERVO, VECTOR
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The armature short-circuit is incorrectly parameterized.
Fault value (r0949, interpret decimal):
Low word: Motor data set number
High word: Cause:
1: A permanent-magnet synchronous motor has not been selected.
101: External armature short-circuit: Output (r1239.0) not connected up.
102: External armature short-circuit with contactor feedback signal: No feedback signal connected
(BI:p1235).
103: External armature short-circuit without contactor feedback signal: Delay time when opening
(p1237) is 0.
201: Internal voltage protection: The maximum output current of the Motor Module (r0289) is less than
1.8 * motor short-circuit current (r0331).
202: Internal voltage protection: A Motor Module in booksize format is not being used.
203: Internal voltage protection: The motor short-circuit current (p0320) is greater than the maximum
motor current (p0323).
204: Internal voltage protection: The activation (p1231 = 4) is not given for all motor data sets with
synchronous motors (p0300 = 2xx, 4xx).
