6.15 Machine Lock
(1) When the "ALL AXES MACHINE LOCK" switch is turned ON, the NC commands for the manual
operation or automatic operation movement can be executed without moving the machine.
The current position display on the setting and display unit will be counted.
(2) The automatic operation speed during machine lock can be selected as the commanded speed or
machine lock speed using the parameters.
• Commanded speed − The movement is executed at the feedrate commanded in the program. Thus,
the time is the same as actual machining.
• Machine lock speed − The movement commands are processed at the rapid traverse rate, and
the dwell time, etc., is ignored. Thus, the program check, etc., can be
carried out faster.
(3) If the "ALL AXES MACHINE LOCK" switch is changed during automatic operation, the automatic
operation will stop after the block currently being executed is completed, and then the setting will be
validated.
(4) During reference point return (G28, G30), the movement will be controlled with the machine lock status
up to the middle point. The machine lock status will be ignored from the middle point to the reference
point.
(5) If the "MACHINE LOCK" switch is changed during manual operation, the setting will be validated after
the feed is stopped once.
(6) The M, S, T and B commands are executed according to the program.
(7) After the axis is moved in the "MACHINE LOCK" ON state, the current position display when the
"MACHINE LOCK" is turned OFF and the machine position will not match.
If AUTO START is pressed in this state, the difference between the current position and the machine
position will be added to the movement amount.
If RESET is pressed, the current position display will change to match the machine position. Thus, after
turning "MACHINE LOCK" OFF, press RESET before starting operation.
