AUTO MACHINE LOCK
—
nTH AXIS
[Function]
During automatic operation, current position (counter) can be changed without actual machine
motion to check program.
These signals are for each control axis, and the number at the end of the signal name indicates the
control axis No.

14 : Automatic machine lock 14th axis
[Operation]
In the automatic operation (memory or MDI), when this signal is ON, the current position (counter)
can be changed on a specific axis (for which the signal is ON) without actual machine motion. If the
signal turns ON in the middle of a block (during motion), block termination occurs after the
completion of that block, and then the machine lock will be valid for the following blocks.
[Related signal]
Manual machine lock, n-th axis (MMLKn: Y44A)
[Cautions]
(1) If auto machine lock signal changes during automatic operation, block stop occurs after
completion of the block in execution.
(2) To move only the table without drilling to confirm the drilling position, turn ON the signal for the
3rd axis (AMLK3) if the drilling axis is the 3rd axis. (Equivalent to Z axis cancel)

MANUAL MACHINE LOCK
—
nTH AXIS
[Function]
During manual operation, current position (counter) can be changed without actual machine motion
to check program.
[Operation]
When this signal is ON, current position can be changed on a specific axis (nth axis) without actual
machine motion. If the signal turns ON or OFF during execution of a block, the operation continues
until it is completed. It is required to stop motion of all axes to validate the machine lock.
These signals are for each control axis, and the number at the end of the signal name indicates the
control axis No.
