PACDRIVE - LMC : Master - Slave CAM

[AndreaArduini]

Goodmorning,

My machine has a CAM Master - Slave managed by PD_AxisModule library in LMC402

I noticed my slave follows the position of the master, visualized  in AXM.ST_ModuleInterface.st_Main.q_lrPositionX, but this value slowly gets different from the real position of master encoder (both real and virtual).

Then, the difference between q_lrPositionX and MasterEncoder.Position increases slowly, so the cam doesn't work. 

Anyone has and idea why that happend ? ... and q_lrPositionX which encoder is linked ?

Thanks a lot for your help..

Hi everyone, 

I solved the problem. 

The points of the CAM weren't correct. That introduced a displacement between q_lrPositionX  and the MasterEncoder.position.
