7.1.5 F1-digit Feed
General
When a one-digit number from 1 to 9 is specified after F, the feedrate
set for that number in a parameter (Nos. 1451 to 1459) is used. When
F0 is specified, the rapid traverse rate is applied.
The feedrate corresponding to the number currently selected can be
increased or decreased by turning on the switch for changing F1-digit
feedrate on the machine operator's panel, then by rotating the manual
pulse generator.
The increment/decrement, DF, in feedrate per scale of the manual pulse
generator is as follows:
X100
maxF
F =∆
Fmax : feedrate upper limit for F1-F4 set by parameter 1460, or
feedrate upper limit for F5-F9 set by parameter 1461
X : any value of 1-127 set by parameter 1450
The feedrate set or altered is kept even while the power is off.
Signal
F1-digit feed select signal F1D<G005#3>
[Classification] Input signal
[Function] Increases or decreases F1-digit speed set by the parameters No. 1451 to
1459 using the manual pulse generator.
Since the manual pulse generator may also be used for axis feeding,
signal F1D (G016#7) designates which function may be used.
[Operation] When the signal is "1", the F1-digit speed can be increased/decreased
using the manual pulse generator.
- If, in automatic operation mode, the tool is not moved under the
control of single-digit F command, single-digit F feedrate
adjustment cannot be performed. Because, however, the manual
pulse generator is reserved for that purpose, the manual pulse
generator cannot be used for axis feed.
- In manual operation mode, this signal is meaningless. Even if it is
"1," manual handle feed is possible.
