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
cables (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.
For bit 09:
When evaluating the encoder signals (track signals, zero marks, absolute values, ...) an illegal signal state was
detected. Check the encoder / state of the encoder signals. Observe the maximum frequencies.
For bit 10:
The internal communication between the SINAMICS components is faulted or interrupted. Check the DRIVE-CLiQ
wiring. Ensure an EMC-compliant design. Observe the maximum permissible quantity structure / clock cycles.
For bit 11:
The infeed is faulted or has failed. Check the infeed and the surroundings (line supply, filter, reactors, fuses, ...).
Check the closed-loop infeed control.
For bit 15:
Group fault. Determine the precise cause of the fault using the commissioning tool.
