840 Dsl C-axis problem

Hello 

           Machine is not working due to these alarms  22295, 231806,  231150,  26106 and    25201.

the story of machine is that c-axis rotary angular encoder Renishaw open with the instruction of machine supplier,   we purchase a new encoder  but still alarms are show, we checked the servo drive IGBT and found ok , we don not understand were is fault  how we can rectified.

Hi sir 

1.    the drive is 1P 6SL3120-1TEA23-0AA3 Single motor module 

2.    ENCODER IS RENISHEW  Model T2001-15A

Hello Sir

 Thanks a lot of your value able response,

Yes You are right and i don't known how to calibrate the encoder. 

Also i noted the R0949 Parameter valve but I can't under stand 

these values are 

R0949 (0) =      - 26214248

R0949 (8) =      - 26214248

R0949 (9) =        41095

With Best regard

Hi Sir.

 Thanks a lot sir

According to Renishaw manual

I try my best to calibrate the encoder but no movement in c-axis because C-axis drive is not ready condition,

when C axis move (rotate) then encoder calibrate the ref marks according to Renishaw manual.

But C - axis not move (rotate) so how I can find out the drive enable signal. why enable signal missing

please guide me how to find out fault,
