The response parameterized in p0290 becomes active.

- adapt the load duty cycle.

230033: Power unit: Hardware current limiting, phase W
Cause:

- closed-loop control is incorrectly parameterized.

- fault in the motor or in the power cables.

- the power cables exceed the maximum permissible length.

- motor load too high

- power unit defective.

Note:

Alarm A30031 is always output if, for a Power Module, the hardware current limiting of phase U, V or W responds.

data identification (p1910 = 1, p1960 = 1).

- check the motor circuit configuration (star/delta).

- check the motor load.

- check the power cable connections.

- check the power cables for short-circuit or ground fault.

- check the length of the power cables.
