Hi Guys,
I bought myself a Used lathe with the Fanuc OI Mate TB.
It displays the error 9027 Position Coder Disconnected.
The previous owner had the same issue and already tried to fix it.
He replaced the SVSP and the Position coder encoder, including the encoder cable.

I like to go through the repair methodically and know that it could be the Position coder/ cable or the servo encoder/cable.
I have a couple questions and hope you can help me answering them.
1. is the Position Coder A860-0309-T302 compatible with the SVSP A06B-6134-H201?
2. The cable of this encoder has only 15 pins on the SVSM side. is this correct?
3. How I can check that the Servo Encoder is gone bad?

Thank you in advance.
Denis
