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

230006 <location>Power unit: Thyristor Control Board
Message -
value:
Drive object: All objects
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 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.
230008 <location>Power unit: Sign-of-life error cyclic data
Message -
value:
Drive object: All objects
Reaction: A_INFEED: NONE (OFF1, OFF2)
SERVO: NONE (OFF1, OFF2, OFF3)
VECTOR: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The power unit has detected that the cyclic setpoint telegrams of the Control Unit were not punctually
updated for at least two clock cycles within a time interval of 20 ms.
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.

230010 <location>Power unit: Sign-of-life error cyclic data
Message -
value:
Drive object: All objects
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
