5. AUTOMATIC OPERATION

NOTE
1 Automatic operation in the machine lock state (M, S,
and 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, and T
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 3rd 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 ZP3) 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.
