F07905 (N, A) External armature short-circuit: Contactor feedback signal "Open" missing
Message value: -
Message class: Application / technological function faulted (17)
Drive object: B_INF, VECTOR_G
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).

F07906 Armature short-circuit / internal voltage protection: Parameterization error
Message value: Fault cause: %1, motor data set: %2
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The armature short-circuit is incorrectly parameterized.
Fault value (r0949, interpret decimal):
zzzzyyxx: zzzz = fault cause, xx = motor data set
zzzz = 0001 hex = 1 dec:
A permanent-magnet synchronous motor has not been selected.
zzzz = 0002 hex = 2 dec:
No induction motor selected.
zzzz = 0065 hex = 101 dec:
External armature short-circuit: Output (r1239.0) not wired.
zzzz = 0066 hex = 102 dec:
External armature short-circuit with contactor feedback signal: No feedback signal connected (BI:p1235). The
feedback signal must be interconnected in all command data sets (CDS).
zzzz = 0067 hex = 103 dec:
External armature short-circuit without contactor feedback signal: Wait time when opening (p1237) is 0.
zzzz = 00C9 hex = 201 dec:
Internal voltage protection: The maximum output current of the Motor Module (r0209) is less than 1.8 x motor short-
circuit current (r0331).
zzzz = 00CA hex = 202 dec:
Internal voltage protection: A Motor Module in booksize or chassis format is not being used.
zzzz = 00CB hex = 203 dec:
Internal voltage protection: The motor short-circuit current (p0320) is greater than the maximum motor current
(p0323).
zzzz = 00CC hex = 204 dec:
Internal voltage protection: The activation (p1231 = 4) is not given for all motor data sets with synchronous motors
(p0300 = 2xx, 4xx).
Remedy: For fault value = 1:
- an armature short-circuit / voltage protection is only permissible for permanent-magnetic synchronous motors. The
highest position of the motor type in p0300 must either be 2 or 4.
