JOG SYNCHRONOUS FEED
—
VALID
[Function]
This is used when the manual feedrate designation is to be per rotation feed (feed rate per spindle
rotation).
[Operation]
(1) The following operation mode feedrates will immediately become per rotation feed when the
"Jog synchronous feed valid" signal is turned ON.
Jog mode
Incremental feed mode
Reference point return mode
When EX.F/MODAL.F is OFF and G0/G1 is ON in the manual random feed mode.
(2) Even if the "Jog synchronous feed valid" signal is ON, the per minute feed will be used in the
following states.
When the dry run signal is ON.
When the "Rapid traverse" signal is ON in the jog, incremental or reference point return
modes.
[Designation of feedrates]
The designation of the per rotation feedrate is the same as the per minute feed input.
The cutting override will be valid when the "Manual override valid" signal is ON.
