13.1 F1-digit Feed
The feedrate registered by parameter can be assigned by designating a single digit following address F.
There are six F codes: F0 and F1 to F5. The rapid traverse rate is applied when F0 is issued which is the same as the G00
command.
When one of the codes from F1 to F5 is issued, the cutting feedrate set to support the code serves as the valid rate com-
mand.
If F6 or larger value is command, the value is regarded as the cutting feedrate which has been directly commanded with
numerical values.
When "F1-digit speed change valid" signal is valid when F1-digit feed is issued, a feedrate which is set by a parameter can
be increased or decreased by operating the manual handle.
Refer to "Programming Manual" for more details on F1-digit feed.
Validate the F1-digit feedrate
To validate the F1-digit feed, the parameter "#1079 f1digt" or "#8145 Validate F1 digit" must be ON.
When the F1-digit feed is valid, the feedrate of each command is as follows:
F0: Rapid traverse rate
F1 to F5: The feedrate configured by the corresponding parameter "#1185 spd_F1" to "#1185 spd_F1"(F1 digit feedrate
F1 to F5)
Enabling conditions of the speed change with the handle
When the F1-digit command is valid, the feedrate can be increased/decreased by operating the first manual handle. (The
feedrate cannot be changed by the 2nd and 3rd handles.)
Changing the feedrate by the handle is available satisfying the following conditions:
(1) The operation must be in automatic start.
(2) The operation must be in cutting feed, and F1-digit feedrate command must be issued.
(3) The F1-digit feed parameter must be ON.
(4) The F1-digit feed switch must be ON.
(5) The operation must not be in handle mode.
(6) The operation must not be in dry run.
(7) Upper limit of F1-digit feedrate ("#1506 F1_FM") and F1-digit feedrate change constant("#1507 F1_K F1") are not zero.
