Currently I'm operating a Kitamura H-800 HMC with a Fanuc 15M control. The problem popped up just yesterday when I tried to jog the table toward negative X direction. The jog speed was extremely low (7.8 in/min). There was no problem jogging the table back toward positive X direction. The other 3 axis appeared to be normal as well when using the jog function. Jogging speed under #1423 in the control was set to 1000 mm/sec.
I tried MDI mode to rapid traverse the table toward ONLY the negative X direction and experienced the same problem as in jogging mode. The same thing can be said when I attempted to run an existing program in Auto mode. Rapid traverse speed with toolpaths relating to the negative X direction was affected.
I appreciate anyone out there that can render an opinion as to what's wrong with the machine.
Thx
