EX. F/MODAL. F
[Function]
This signal selects whether a manual random feed in G1 mode is done at manual feed rate or at
modal speed in automatic operation.
[Operation]
When the "G0/G1 select" (CXS4) signal explained later is ON, the "CXS3" signal works as follows:
(1) When EX.F/MODAL.F (CXS3) is OFF:
When the "Manual feedrate (JVS)" signal is OFF, the speed selected by the manual feed rate
(*JV1~*JV16) applies.
When the "Manual feedrate (JVS)" signal is ON, the applicable speed is determined by the
relation between the contents of the corresponding file register (R) and the feed rate unit (PCF1
or PCF2).
(2) When EX.F/MODAL.F (CXS3) is ON:
Manual random feed is done at a modal speed (F***) set in automatic operation. However,
manual random feed will not be done, if no F command has been executed before.

F command modal (F***)

G0/G1
[Function]
This signal selects a manual feed speed or rapid traverse speed in manual random feed mode.
[Operation]
This signal operates as shown below depending on the status of the G0/G1 select (CXS4) signal.
(1) When the G0/G1 select signal is OFF:
The rapid traverse speed originally set to the corresponding axis applies. Rapid traverse
override is also valid. The rapid traverse speed applicable when moving two or more axis
components at the same time varies with the status of the "Axis independent (CXS2)" signal.
See the descriptions on the "Axis independent (CXS2)" signal.
(2) When the G0/G1 select signal is ON:
The manual feed speed or the speed specified by the F command in automatic operation apply.
For details, see the description on the EX.F/MODAL.F (CXS3).
