dear members,
thanks to all will help me, i have a knuth lathe with this fagor cnc electronic, few time ago he
started giving an error 2000 external emergency active
PLC msg Error 49and50 after searching everywere, with no solutions because heavy amount of work
to finish we bypassed the problem removing the emergency protection.
now with work near nothing (covid effects) i stopped this lathe, and decided to give a renew of it,
then after doing a haavy control we found that a over-travel micro was broken, and a cable inside the machine was
brocken then i removed all the parts cleaned and then changed all the emergency cables, emergency stop buttons and the brocken micro,
then reconnecting all. The lathe after resetting stay with a message, PLC Msg Error 49-50 and if i move the x axis work ok,
instead if i move the z axis toward the spindle ok, if i move it toward tailstock it don't move and apear the error
1202 z axis overtravel error or something like this.
also if i try to search zero point give same error.
if i get zero point of spindle is ok
so the lathe don 'work .. can someone give me a suggestion of what can have been happend?
what have to verify? maybe when we changed cables a loosen cable disconnected?
we controlled everything but found nothing brocken .. disconnect. no blown fuses
thank you very much to all will help us to solve the problem
sincerelly sergio.
