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.
For fault value = 101:
- the contactor for the external armature short-circuit configuration should be controlled using output signal r1239.0.
For instance, the signal can be connected to an output terminal via binector input p0738. Before this fault can be
acknowledged, p1231 must be set again.
For fault value = 102:
- if the external armature short-circuit with contactor feedback signal (p1231 = 1) is selected, this feedback signal
must be connected to an input terminal (e.g. r722.x) and then connected to BI: p1235.
- alternatively, the external armature short-circuit without contactor feedback signal (p1231 = 2) can be selected.
For fault value = 103:
- if the external armature short-circuit without contactor feedback signal (p1231 = 2) is selected, then a delay time
must be parameterized in p1237. This time must always be greater than the actual contactor opening time, as
otherwise the Motor Module would be short-circuited!
For fault value = 201:
- a Motor Module with a higher maximum current or a motor with a lower short-circuit current must be used. The
maximum Motor Module current must be higher than 1.8 x short-circuit current of the motor.
For fault value = 202:
- for internal voltage protection, use a Motor Module in booksize or chassis format.
For fault value = 203:
- for internal voltage protection, only use short-circuit proof motors.
For fault value = 204:
- the internal voltage protection must either be activated for all motor data sets with synchronous motors (p0300 =
2xx, 4xx) (p1231 = 3) or it must be deactivated for all motor data sets (p1231 not equal to 3). This therefore ensures
that the protection cannot be accidentally withdrawn as a result of a data set changeover. The fault can only be
acknowledged if this condition is fulfilled.
F07907 Internal armature short-circuit: Motor terminals are not at zero potential after pulse
suppression
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: Power Module Propagation: GLOBAL
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.
