But the problem was that i couldn't move the Z axis in JOG mode nor in AUTO, i can only move it with the HANDLE.
I did my research and found out that there is a z axis interlock signal, it was shown in the diagnostic parameter DGN 128: 00000011 and the parameter PRM008#7 is 1 so the interlock is only effective on the Z axis.
I looked for what triggering this signal in the ladder diagram and found this (please check the attached picture)
G128 corresponds to DGN 128, but i don't know what's Y049.1 and what it corresponds to,it might be a switch that is not active i'm not sure i'm still looking in some hardware and installation manual i found online.
I'm still new to this any help would be much appreciated, what should i do next ? is there an option to override this interlock signals by changing some parameters ? or should i keep looking for what is triggering this interlock?
Thanks in Advance!
