External fault 3 is initiated by the following AND logic operation:
- BI: p2108 negated
- BI: p3111
- BI: p3112 negated
Dependency: Refer to: p2108, p3110, p3111
Refer to: F07862

Note: For bit 00:
Hardware or software malfunction was identified. Carry out a POWER ON of the component involved. If it occurs
again, contact Technical Support.
For bit 01:
A line supply fault has occurred (phase failure, voltage level, ...). Check the line supply / fuses. Check the supply
voltage. Check the wiring.
For bit 02:
The DC link voltage has assumed an inadmissibly high value. Check the dimensioning of the system (line supply,
reactor, voltages). Check the infeed settings.
For bit 03:
An inadmissible operating state of the power electronics was identified (overcurrent, overtemperature, IGBT failure,
...). Check that the permissible load cycles are maintained. Check the ambient temperatures (fan).
For bit 04:
The temperature in the component has exceeded the highest permissible limit. Check the ambient temperature /
control cabinet cooling.
For bit 05:
A ground fault / inter-phase short-circuit was detected in the power cables or in the motor windings. Check the power
cable (connection). Check the motor.
For bit 06:
The motor was operated outside the permissible limits (temperature, current, torque, ...). Check the load cycles and
limits that have been set. Check the ambient temperature / motor cooling.
For bit 07:
The communication to the higher-level control system (internal coupling, PROFIBUS, PROFINET, ...) is faulted or
interrupted. Check the state of the higher-level control system. Check the communication connection/wiring. Check
the bus configuration / clock cycles.
For bit 08:
A safety operation monitoring function (Safety) has detected an error.
