Feed Per Minute Function (G94); Inverse Time Feed (G93) - Siemens SINUMERIK 802D sl Programming Manual

04.07
Note
1. If F1--digit command is activated by setting MD $MC_FIXED_FEE-
DRATE_F1_F9_ON = TRUE and F1 to F9 should not be used, be sure to pro-
gram the feedrate F as a REAL value. For example, not F1 but F 1.0 for 1 mm/
min.
2. If "F0" is specified, it is switched to rapid traverse mode (G00) automatically.
Subsequently, G01 needs to be specified in order to use F1--digit command.
3. When the DRY RUN switch is ON, feed commands are all executed at the fee-
drate set for the dry run operation.
4. The feed override function is invalid for the feedrate selected by the F1-digit
command.
5. The feedrate set for setting data is retained in memory if the power is turned
OFF.
6. In a macro call using G65/G66, the value commanded with address F is always
stored in system varible $C_F, meaning that numeral values 1 to 9 will stored.
7. If F1--digit command is used in a machining program containing a cycle call
(G81 to G87), the feedrates are read from the corresponding setting data and
stored into variable $C_F.
Example
$SC_EXTERN_FIXED_FEEDRATE_F1_9[0] = 1500.0
$SC_EXTERN_FIXED_FEEDRATE_F1_9[1] = 550.0
N10 X10 Y10 Z10 F0 G94 ; Positioning, rapid traverse
N20 G01 X150 Y30 F1 ; feedrate 1500 mm/min active
N30 Z0 F2 ; feedrate 550 mm/min active
N40 Z10 F0 ; Positioning, rapid traverse
1.2.4

Feed per minute function (G94)

When G94 is designated, a feedrate specified following address F is executed in
units of "mm (inch)/min".
1.2.5

Inverse time feed (G93)

When G93 is designated, a feedrate specified following address F is executed in
units of "1/min". G93 is a modal G code.
Example
N10 G93 G1 X100 F2 ;
i.e. the programmed distance will be moved within half a minute.
