MANUAL OVERRIDE VALID
[Function]
Override can be exerted on "Manual feedrate" (feedrate in JOG feed, incremental feed, etc. during
manual operation).
[Operation]
When this signal (OVSL) is turned ON when manual feedrate has been set, the previously set
cutting feedrate override (%) is applied to that feedrate.
Manual feedrate
(1) Code mode (*JV1~*JV16)
(2) File register mode
(Note) For details of "Manual feedrate", "Cutting feedrate override" and "2nd cutting feedrate
override", refer to the relevant descriptions.

FUNCTION LOCK
[Function]
Strobe signal for miscellaneous function (M, S, and T) specified during automatic operation cannot
be output when this signal is used. The signal (AFL) can be used to check machining program, for
example.
[Operation]
When the signal (AFL) turns ON ...
(1) Miscellaneous function (M, S, and T) specified in automatic operation cannot be executed, i.e.
output of code data and function strobe signal (MF1~MF4, SF1, TF1) are withheld.
(2) If the signal turns ON after code data is output, that output is accepted and the corresponding
function can be completed (FIN1 or FIN2 is received and strobe signal is set to "0").
(3) Miscellaneous function M00, M01, M02 or M30 is, however, accepted and realized even when
the signal (AFL) is ON ... code data and M function strobe signal are output.
(4) Miscellaneous function which is executed within the controller and not output, such as M98 and
M99, is executed even when the signal is ON.
