(3) In the MACHINE LOCK Position
As the program commands are executed manually or automatically, the position data are
updated according to the execution of the commands while the machine is not actually
operated. With this setting, the M, S, T, and B* functions are executed normally.
This is used for manually presetting the display or for checking the tape. Note that the
reference point return operation is not executed if the switch is placed in the MACHINE
LOCK position.Auxiliary Function Lock
2.7.5 Auxiliary Function Lock
The AUX FUNCTION LOCK switch on the machine operation panel is used to check the NC
tape in combination with the MACHINE LOCK function. When the switch is ON, the M, S, T,
and B* function commands are disregarded. When the switch is turned ON during automatic
operation, the function becomes valid from the block next to the presently executed block.
1. The M00, M01, M02, and M03 codes are processed normally.
2. Both the decode signal and BCD code are output. However, BCD code is not output with
M90 to M99 (internally processed M codes); BCD code is not output inherently with these
M codes.
3. The AUX FUNCTION LOCK switch setting is invalid for the S5-digit commands.
2.7.6 Z-axis Command Neglect
The Z-AXIS COMMAND NEGLECT switch is used to execute a program only in the XY plane.
When the switch is ON, the program is executed with the machine lock function applied only to
the Z-axis. Although the Z-axis does not move, position data of the Z-axis is updated as the pro-
gram is executed. The switch can be operated only while the operation is stopped in the block
stop or feed hold state.
2.7.7 4th-axis Command Neglect
When the 4TH-AXIS COMMAND NEGLECT switch is ON, the program is executed with the
machine lock function applied only to the 4th-axis. Although the 4th-axis does not move, posi-
tion data of the 4th-axis are updated as the program is executed. The switch can be operated only
while the operation is stopped in the block stop or feed hold state.5th-axis Command Neglect
When the 5TH-AXIS COMMAND NEGLECT switch is ON, the program is executed with the
machine lock function applied only to the 5th-axis. Although the 5th-axis does not move, posi-
tion data of the 5th-axis are updated as the program is executed.
The switch can be operated only while the operation is stopped in the block stop or feed hold
state.
