NX-ECS212 SSI Encoder Card: How to change Actual value

[Jotove 0]

I have a machine with NJ501-1400 controller.
I have some NX-ECS212 SSI encoder input cards.
I use Encoder axis with that SSI encoders.
I need to change the encoder axis value with the real value of the machine.
I tried to use "MC_HomeWithParameter" instruction but I cannot do it because must'nt be used with encoder axis.
If I put it at a virtual encoder axis I cannot change actual axis position.
I tried to use "MC_SetPosition" instruction but it isnt retentive area and when I lost power I lost reference value too.
How can I do it?
Thanks!

Did you set it as an absolute encoder in the axis setup?
