Acceptance test STO deselect ProfiSafe

Hello,

I have a fully commissioned system that has been running for several years.  A power surge has neccesitated the replacement of a drive (G110M CU240M PN).

PLC is CPU 1513F-1 PN

The drive was STO via ProfiSafe.

I have run through the drive commissioning tools and had the drive function to test direction since replacement.  I cannot restart the system as it requires an acceptance test.  I cannot perform the acceptance test as it will not enable the STO over profisafe due to the drive connection issue.  It simply says deselect STO.  The other drives are recieve the STO signal and i can witness it change state when monitored.  However on the new drive the STO does not change. 

The telegrams are setup exactly the same.  After multiple other attempts we have been advised to delete and recreate the drive.  This approach ended in the same results.

I have checked to see if it requires reintegration after passivation, but the ACK_REQ is False.

Setting ACK_REI to true has no effect.

Any advice would be greatly appreciated. 

Thanks

Hello ShabbyBadger,

what error messages can you see in the drive commissioning tool?
According to your description I would expect that F01650 is active.

Check the fault value of message F01650. Depending on the fault value you can acknowledge the fault or not. Check out G110M list manual for details.
