Siemens G130 List Manual page 1651

Remedy: - reduce the continuous load.
- adapt the load duty cycle.
- check the motor and power unit rated currents.

F30006 Power unit: Thyristor Control Board
Message value: -
Message class: Power electronics faulted (5)
Drive object: B_INF, VECTOR_G
Component: Power Module
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The Thyristor Control Board (TCB) of the Basic Line Module signals a fault.
- there is no line supply voltage.
- the line contactor is not closed.
- the line supply voltage is too low.
- line supply frequency outside the permissible range (45 ... 66 Hz).
- there is a DC link short-circuit.
- there is a DC link short-circuit (during the precharging phase).
- the motor either has a short-circuit or insulation fault (from an inverter connected to the DC link).
- 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.
- check the motor 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: B_INF, VECTOR_G
Component: Control Unit (CU)
Reaction: Vector: NONE (OFF1, OFF2, OFF3)
Infeed: NONE (OFF1, OFF2)
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: - for projects with the VECTOR drive object, check whether p0117 = 6 has been set on the Control Unit.
- increase the fault threshold (p7789).
- check the Motor Module, and if required replace.
