(e) Axis interlock is input
Check the bit status on the I/O monitor screen. If “O”, the corresponding axis cannot
move.
(f) Machine lock is ON
• Even when the machine lock function is ON, position display changes. Check the
input of the machine lock switch (I/O monitor, 3006 D5 = 0). If “1”, the axes do
not move.
• Check the internal toggle switch (parameter pm0000 D1 = 0). If “1”, the axes do
not move.
(5) Manual Reference Point Return is Incorrect
The following explanation is given assuming that jog and rapid traverse are executed cor-
rectly.
(a) Manual reference point return signal is not input
Check the I/O monitor #3007 D0. The status must be” 1”.
Otherwise, the axis continues moving to OT at the same feedrate even if it reaches
point A. Refer to Fig. 9.7.
(b) Jog or rapid traverse mode is not selected
I/O monitor #3000 D0 or D1 must be”1”.
