MANUAL FEEDRATE
[Function]
Feedrate in manual operation (JOG mode, INCREMENT mode, etc.) or in dry run of automatic
operation (memory or MDI) is selected.
[Operation]
This signal is valid in the following cases, but will be invalid when the rapid traverse signal (RT) is
ON.
(1) Jog mode, incremental mode or reference point return mode is ON.
(2) During cutting feed in automatic operation and "dry run" signal (DRN) is ON.
(3) Dry run signal is ON during rapid traverse in the automatic operation. Note that parameter "G00
dry run" must be ON.
These signals (*JV1~*JV16) are set with the code method. The relation is shown below.

If *JV 1 to *JV16 are all OFF, the previous value will be maintained. The value will be set to 0
when the power is turned OFF.
(Note 1) In JOG mode, true feedrate changes if this signal changes during feed motion.
(Note 2) In incremental feed mode, true feedrate does not change if this signal changes during feed
motion.
