21.3.1.18 DRY RUN INPUT (DRN #30064)
This input is used so that the feed operations in automatic mode part program execution are
performed at a speed specified by the manual continuous feed selection input (JV1, JV2, JV4,
JV8, or
6).
While the DRN input is closed during automatic mode part program execution, cutting feed is
effected at a speed specified by a manual continuous feed selection input and not at a prog-
rammed speed. (However, threading is performed at a programmed speed. )
If the DRN input is closed or opened while the control is engaged in automatic operations,
the feedrate changes accordingly in the middle of the current block execution.
NOTE
. When parameter pm2000 DO
❑
1 with the DRN input closed, the
drate for the positioning command is rendered the same as the
selected manual continuous feedrate.
When parameter pm2000 D1 = 1 with the DRN input closed, the
drate for the threading command is rendered the same as the
selected manual continuous feedrate.
21.3.1.19 MACHINE LOCK (MLK #30066)
This input prevents the control output pulses from being delivered to the servo unit.
When the MLK input is closed, the logic circuits distribute pulses but do not initiate
ment while the control is engaged in automatic or manual operations.
axis
As the logic circuits distribute pulses, the current value display changes with the instructions.
The control must be stopped when the MLK input is closed or opened. The operations are
not affected except during block stoppage or feedhold state.
21.3.1.20 AUXILIARY FUNCTION LOCK INPUT (AFL #30067)
This input excludes the M/T function from automatic mode part program execution,
When the AFL input is closed, the control disregards the program M/T command during part
program execution. However, the M code decoded outputs (MOOR, MO1 R, M02R, are
generated.
If the AFL input is closed or opened in the middle of part program execution, program execu-
tion is affected by the AFL input beginning with the block next to the currently executed block.
