Dear All,
In oerlikon gear cutting machine, cutter spindle is A axis
Error 25000 A axis active encoder fault appears soon after switching on the system
We checked following :
a) Cable continuity from Motor upto 611 control card - found ok in Digital multimeter in Resistance Mode
Checked continuity between connector on junction box over Motor and cable plugged on encoder found OK
b) Interchanged control card from other axis (Siemens Part number is same for both the control cards)
c) Replaced Motor encoder with New one
d) Old NC archieve loaded to ensure nothing wrong with parameters but same alaram
Kindly advice what else could be the reason
Best Regards,
