Power Unit: Sign-Of-Life Error Cyclic Data; Power Unit: Line Phase Failure In Main Circuit - Siemens SINAMICS DCM List Manual

- there is a DC link short-circuit.
- there is a DC link short-circuit (during the pre-charging phase).
- voltage supply for the Thyristor Control Board outside the nominal range (5 ... 18 V) and line voltage >30 V.
- there is an internal fault in the Thyristor Control Board.
Remedy: The faults must be saved in the Thyristor Control Board and must be acknowledged. To do this, the supply voltage of
the Thyristor Control Board must be switched out for at least 10 s!
- check the line supply voltage
- check or energize the line contactor.
- check the monitoring time and, if required, increase (p0857).
- if required, observe additional power unit messages/signals.
- check the DC link regarding short-circuit or ground fault.
- evaluate diagnostic LEDs for the Thyristor Control Board.
F30008

Power unit: Sign-of-life error cyclic data

Message value: -
Message class: Internal (DRIVE-CLiQ) communication error (12)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The Control Unit has not punctually updated the cyclic setpoint telegram. The number of consecutive sign-of-life
errors has exceeded the fault threshold (p7789).
Remedy: - check the electrical cabinet design and cable routing for EMC compliance
- for projects with the VECTOR drive object, check whether p0117 = 6 has been set on the Control Unit.
- increase the fault threshold (p7789).
A30010 (F) Power unit: Sign-of-life error cyclic data
Message value: -
Message class: Internal (DRIVE-CLiQ) communication error (12)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: NONE
Acknowledge: NONE
Cause: A DRIVE-CLiQ communication error has occurred between the Control Unit and the power unit involved.
The cyclic setpoint telegrams of the Control Unit were not received on time by the power unit for at least one clock
cycle.
Remedy: Check the electrical cabinet design and cable routing for EMC compliance.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
F30011

Power unit: Line phase failure in main circuit

Message value: %1
Message class: Network fault (2)
Drive object: DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY
Cause: At the power unit, the DC link voltage ripple has exceeded the permissible limit value.
Possible causes:
- A line phase has failed.
- The 3 line phases are inadmissibly unsymmetrical.
- The capacitance of the DC link capacitor forms a resonance frequency with the line inductance and the reactor
integrated in the power unit.
- the fuse of a phase of a main circuit has ruptured.
- A motor phase has failed.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
