Note
NOTE
1 Automatic operation in the machine lock state (M, S, T, and B
commands)
Machine lock applies only to move commands along
controlled axes. Updating modal G codes or setting a
coordinate system is performed normally. M, S, T, and B (2nd
auxiliary function) commands are also performed normally.
2 Reference position return in the machine lock state (G27,
G28, and G30)
When the reference position return command (G28), or 2nd to
4th reference position return command (G30), is executed for
an axis in the machine lock state, distribution and position
updating are performed. The tool, however, is not returned to
the reference position. The reference position return
completion signals (ZP1 to ZP4) are not output.
The reference position return check command (G27) is
ignored in the machine lock state.
3 Turning on/off the machine lock signal during movement
along an axis
When the machine lock signal for an axis is set to 1 during
movement along the axis that is not in the machine lock state,
the axis is immediately placed in the machine lock state and
output pulses (move commands) to the servo motor are
stopped. The tool is decelerated and stopped with the
automatic acceleration/deceleration function.
On the other hand, when the machine lock signal for an axis
is set to 0 during distribution of the move command along the
axis in the machine lock state, pulse (move command) output
for the axis is immediately restarted. The tool is accelerated
with the automatic acceleration/deceleration function.
