F07907
Internal armature short-circuit: Motor terminals are not at zero potential after pulse suppression
Message value:
-
Drive object:
All objects
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
The function "Internal voltage protection" (p1231 = 3) was activated.
The following must be observed:
- when the internal voltage protection is active, after pulse suppression, all of the motor terminals are at half of the DC link
voltage (without an internal voltage protection, the motor terminals are at zero potential)!
- it is only permissible to use motors that are short-circuit proof (p0320 < p0323).
- the Motor Module must be able to continually conduct 180% short-circuit current (r0331) of the motor (r0289).
- the internal voltage protection cannot be interrupted due to a fault response. If an overcurrent condition occurs during
the active, internal voltage protection, then this can destroy the Motor Module and/or the motor.
- if the Motor Module does not support the autonomous, internal voltage protection (r0192.10 = 0), in order to ensure safe,
reliable functioning when the line supply fails, an external 24 V power supply (UPS) must be used for the components.
- if the Motor Module does support the autonomous, internal voltage protection (r0192.10 = 1), in order to ensure safe,
reliable functioning when the line supply fails, the 24 V power supply for the components must be provided through a
Control Supply Module.
- if the internal voltage protection is active, it is not permissible that the motor is driven by the load for a longer period of
time (e.g. as a result of loads that move the motor or another coupled motor).
Remedy:
Not necessary.

A07908
Internal armature short-circuit active
Message value:
-
Drive object:
All objects
Reaction:
NONE
Acknowledge:
NONE
Cause:
The Motor Module signals that the motor is short-circuited through the power semiconductors (r1239.5 = 1). The pulses
cannot be enabled. The internal armature short-circuit is selected (p1231 = 4):
Remedy:
For synchronous motors, the armature short-circuit braking is activated with binector input p1230 = 1 signal.
F07909
Internal voltage protection: Deactivation only effective after POWER ON
Message value:
-
Drive object:
All objects
Reaction:
NONE
Acknowledge:
POWER ON
Cause:
The deactivation of the internal voltage protection (p1231 not equal to 3) only becomes effective after POWER ON.
The status signal r1239.6 = 1 indicates that the internal voltage protection is ready.
Remedy:
Not necessary.
