Dear Sir

We have got a Grinding Machine with Fanuc 0iTC CNC and alpha I drives, with FSSB communication

This machine has got 2 numbers of dual axes drives, first drive for X and C, 2nd drive for Z1 (ie Z) and Z2 (ie Y)

Error 368 : Y axis Serial Data Error (INT) appeared

When we interchanged cables JF1 and JF2 in 2nd drive, then Error 368 : Z axis Serial Data Error (INT) appeared, we did not find any problem in cable JF2 ie error 368 is due to faulty fanuc Pulse coder of the Y or Z2 Motor

We need to bypass Y or Z2 axis and for this, we changed Parameter 2009 bit 0 (DMY) for Y axis to 1, taken out JF2 from drive and put a dummy connector with pin numbers 11 and 12 short, now error 466 : Y axis Motor/AMP combination is appearing

Originally Parameter 1023 X = 1, Z = 2, Y =3, C =4

Changed Parameter 1023 for Y from 3 to -128

After power off and ON,, error 400 : Y axis VRDY ON, 404 : C axis VRDY ON and error C axis Digital Parameter appeared



Pl let us know on how to bypass one axis out of dual axis drive ??????

Best Regards,
