Hi,
I got a problem with my Z axis on my mori mill with fanuc 10M controller. Ocassionally when i program a move in Z direction with G0 in MDI, then the Z axis starts to move at full speed (does not care about rapid feed override switch, really very fast) in either direction until an EXCESS MOVE alarm is raised. The alarm is raised after some travel, once it was few cm's, next time cca 25cm. This seems to be very dangerous, until now seems i got lucky enough the spindle moved upwards.
There is one more thing worth to mention - last two times it happened after i ran a long program via rs232 (ran ok, then i wanted to move the spindle to a certain position), the last command was G28G0Z0, which i used to interrupt in half way with the reset button.
Any suggestions?
thanks in advance
