# CPU Load (105)

The processor performance has reached a critical value.

The cause of the error can be detailed by the Sub-ID:

### 0 - Waveform Tick CPU load too high

The Waveform Tick is the processor task in which run all the calculations of the inverter. The control frequency is twice as high as the switching frequency in parameter setting. For most devices the control frequency is 6 kHz. If the Waveform Tick repeatedly could not be completed within this period the fault is triggered by the Sub-ID 0.

### 1 - Millisecond Tick CPU load too high

The millisecond tick is the processor task in which all other cyclic processes are performed with a lower priority. It is performed with a fixed clock frequency of 1 kHz. If the millisecond tick repeatedly could not be completed within this period the error is triggered by Sub-ID 1

## Fehleraktion

Ein Not-Aus wird durchgeführt.

## Troubleshooting

The error can be acknowledged by an Error-Reset. Depending of the cause of the error (see above) there may be a hardware defect which musst lead to the replacement of the inverter. motor or cable.
