21.3.1.22 EDIT LOCK INPUT (EDT LK #30072)
This input prevents the contents of the control part program memory from being changed,
When the EDTLK input is closed, part program storage into memory and part program correc-
tions with keys are prohibited during program editing.
21.3.1.23 SETUP POINT RETURN INPUT (SRN #30077)
This input accomplishes positioning at the selected coordinate position in the manual jog mode.
While the SRN input is closed, manual jog feed stops when the setup point is reached. When
the machine is positioned at the setup point, manual jog feed cannot be initiated until the SRN
input opens.
21.3.1.24 AUTOMATIC MODE HANDLE OFFSET INPUT # 30081)
When a manual pulse generator is provided, this input allows you to move the machine with the
manual handle even in the automatic operation mode (tape operation, manual data input opera-
tion, or memory operation mode).
With this input, it is possible to offset any displacement resulting from work mounting during
automatic operations.
While the HOFS input is closed, the machine can be moved with the manual pulse generator
even if the control is in the automatic operation mode. However, the manual pulse
does not evoke machine movement while the positioning command is being executed in the
automatic operation mode.
The manual pulse generator movement axis is determined by the HI -H8 (manual handle feed
axis selection) inputs.
When the multiple axis pulse generator is provided, it is possible to move the machine along a
number of axes. The distance moved per step provided by the manual pulse generator is de-
termined by the MP1, MP2, or MP4 (manual handle magnification setup) input.
NOTE
1. In an alarm condition (the ALMS or output is closed), the auto-
matic mode handle offset function is disabled.
2, To initiate automatic mode handle offset movement, parameters
DO (first axis) through pm2002 D7 (eighth axis) must be set to 1.
3. When parameter pm2003 is set to 1, the automatic mode handle
offset movement is limited to the interpolation period of the automatic
operation mode.
21.3.1.25 MACHINING INTERRUPT POINT RETURN INPUT # 30082) AND MACHIN-
ING INTERRUPT POINT RETURN COMPLETION OUTPUT #35051)
When the machine has been manually operated after mode switching from automatic to manual,
the CPRN input is used to manually return the machine to the automatic mode interrupt point.
. .
When the machine is moved to the machining interrupt point with the CPRN input closed, the
manual jog mode movement stops.
While the machine is positioned at the machining interrupt point, manual jog mode movement
does not start until the CPRN input opens.
When all axes of a certain program are returned to the machining interrupt points with the
CPRN input closed, the CPRNS output closes.
