Cause : SI P1 Write request for parameter rejected comes when the write request for one or several Safety Integrated parameters on processor 1 was rejected.

Note: This fault does not result in a safety stop response.

For fault value = 1:
- set the Safety Integrated password (p9761).

For fault value = 2:
- Inhibit Safety Integrated (p9501, p9601) or reset safety parameters (p0970 = 5), then reset the drive parameters again.

For fault value = 3:
- end the simulation mode for the digital input (p0795).

Re fault value = 10, 14, 15, 18, 20:- check whether there are faults in the safety function alignment (F01655, F30655) and if required, carry out diagnostics for the faults involved.
- use a Control Unit that supports the required function.

For fault value = 21:
- use a Power Module that supports the Safety Integrated functions
