Cause : Write request for parameter rejected comes when the write request for one or several Safety Integrated parameters on processor 2 was rejected.

Fault value (r0949, interpret decimal):

10: An attempt was made to enable the STO function although this cannot be supported.
15: An attempt was made to enable the motion monitoring functions integrated in the drive although these cannot be supported.
16: An attempt was made to enable the PROFIsafe communications although this cannot be supported.
18: An attempt was made to enable the PROFIsafe function for Basic Functions although this cannot be supported.
20: An attempt was made to simultaneously enable both the drive-integrated motion monitoring functions via integrated F-DI and STO via terminals, even though these cannot be supported at the same time.

Re fault value = 10, 15, 16, 18:

- 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.
