3. When the DRY RUN switch is ON, feed commands are all executed at the feedrate 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 the parameter is retained in memory if the power is turned OFF.
6. It is possible to designate an F1-digit command by specifying a variable in a macro pro-
gram.
7. With the inch specification, feedrates are set in units of inch/min. However, the allowable
maximum feedrates can be set only in units of mm/min.
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 Solid Tap Mode (G93, G94) *
The following G codes are used to indicate that tapping should be executed by using the solid tap
function.
Table 1.2.5.1: Solid Tap Mode G Codes
G93 and G94 are modal G codes. When the power is turned ON or when the NC is reset, the G94
mode is automatically set.
(1) Solid Tap Mode (G93)
In the G93 solid tap mode, solid tapping is executed for the tapping cycles called by G84 or
G74. Axis feed is controlled in the “feed per revolution” mode. In the solid tap mode, only
solid tapping is allowed and no other operation is possible.
(2) Solid Tap Mode Cancel (G94)
When G94 is executed, the solid tap mode is canceled. After the cancellation of the solid tap
mode, conventional type tapping is executed in which axis feed is controlled in the “feed per
minute” mode.
