Hello dear coleagues.

I have comissioned one machine in wich there is a Simodrive Posmo CA, we have configured this Simodrive to work in angular position motion control mode; so far we are able to get the servomotor running and it is working pretty good; the only issue we have is that when we turn off the power of the machine, and then we turned on, the Simodrive unit loose the reference position; when we go Online with the device and we check the faults and warnings we found this:

149 Incorrect data for modulo axis with absolute encoder. Supplementary info \%u

We have re-referenced the unit several times, but every time we turn off the machine the reference is loosed again.

How can we avoid to loose reference when we turn off the machine? I'm attaching a file with the configuration and parameters we have loaded into device.

Thanks all you for your help, have a nice day .
