CREATED CONVERSATIONALLY

When a conversational machining program is executed directly, a feedrate
override value can be memorized for each process.
This function can be enabled by setting bit 7 (OPB) of parameter No. 9765
to 1.
(1) Override teaching
When a conversational machining program is executed, a feedrate
override value, set on the operator’s panel, can be memorized by
each process (override teaching) by using the execution in–progress
screen (Section 12.2.1).
(a) The execution in–progress screen is displayed during the direct
execution of a conversational machining program.
(b) When a two–path lathe is used, the tool post for which override
teaching is used can be specified using [HEAD L]/[HEAD R].
Override teaching can be specified for use with both tool posts at
the same time. The soft key corresponding to a specified tool post
is displayed in reverse video.
(c) When [OVR TEACH] is pressed, the following message and soft
keys are displayed:
EXEC CAN
(ACTUAL SPEED)
F: 2000 MM/MIN
S: 800 RPM
OVR–PLAY BACK
PRC OVRD 80%
EXEC REALLY? YES [EXEC] NO: [CANCEL]
(d) By pressing [EXEC], the feedrate override value currently set on
the operator’s panel is memorized. When [CAN] is pressed, the
previous screen is redisplayed.
NOTE
1 Override teaching is performed only for the process being
executed when [OVR TEACH] is pressed. Even if the next
process is started before the teaching operation has been
completed, a feedrate override value is memorized in the
process being executed when [OVR TEACH] is pressed.
2 When bit 6 (OPR) of parameter No. 9765 is set to 0:
Override teaching cannot be performed when the memory
protect switch is set.
When bit 6 (OPR) of parameter No. 9765 is set to 1:
Override teaching can be performed even when the
memory protect switch is set.
