6.15 F 1-digit Feed

6.15 F 1-digit Feed
6.15.1 Outline
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
command.
If F6 or larger value is command, the value is regarded as the cutting feedrate which has been directly commanded with
numerical values.
When an F1-digit command has been issued, the external output signal is output.
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.
6.15.2 Detailed Description
(1) When the programmed feedrate has been issued as an F 1-digit command, the feedrate can be increased or
reduced by turning the manual handle when turning ON the "F 1-DIGIT FEED" switch.
The feedrate cannot be changed by the 2nd and 3rd handles.
(2) The increase/decrease amount per handle gradient is expressed with the following equation.
(Example) For a 10mm/min. increase/decrease amount per handle gradient:
If F max = 3600mm/min :
(3) The acceleration/deceleration method follows the rapid traverse setting when F0 is issued. But G modal does not
change.
(4) F1-digit feed command is valid in a G01, G02, G03, G02.1 or G03.1 modal.
(5) F1-digit feed command can be used for fixed cycle.
(6) F1-digit feed command is a modal command.
(7) The number of manual handle pulses is 1 pulse per scale unit regardless of the scaling factor.
(8) During a F1-digit feed command, the F1-digit feed number and F1-digit feed command signal are output as the PLC
signals.
The conditions for validation are as follows:
(1) The operation must be in automatic start.
(2) The operation must be in cutting feed, and F 1-digit feedrate command must be issued.
(3) The F 1-digit feed parameter must be ON.
(4) The F 1-digit feed switch must be ON.
(5) The operation must not be in machine lock.
(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.

FM : Upper limit of F 1-digit feedrate (#1506 F1_FM)
K : F 1-digit feedrate change constant (#1507 F1_K)
∆ F = 10 = 1 ×

Thus, K = 360.
