3.7 MANUAL NUMERIC COMMAND
General
The manual numeric command function allows data programmed by
MDI to be executed in the jog mode. Whenever the system is ready for
jog feed, a manual numeric command can be executed. The following
eight functions are supported:
(1) Positioning (G00)
(2) Linear interpolation (G01)
(3) Automatic reference position return (G28)
(4) 2nd, 3rd or 4th reference position return (G30)
(5) M codes (miscellaneous functions)
(6) S codes (spindle functions)
(7) T codes (tool functions)
(8) B codes (second auxiliary function)
Explanation
- Positioning
The amount of travel is given as a numeric value, preceded by an
address such as X, Y or Z. This is always regarded as being an
incremental command, regardless of whether G90 or G91 is specified.
The tool moves along each axis independently at the rapid traverse rate.
Linear interpolation type positioning (when the tool path is linear) can
also be performed by setting bit 4 (LRP) of parameter No. 1400.

NOTE
When manual rapid traverse selection signal RT is
set to 0, the jog feedrate along each axis is clamped
to the feedrate set in each of the following
parameters according to the setting of bit 4 (LRP) of
parameter No.1400:
When bit 4 (LRP) of parameter No. 1400 = 0: Jog
feedrate along each axis (parameter No. 1423)
When bit 4 (LRP) of parameter No. 1400 = 1: Rapid
traverse rate along each axis (parameter No. 1420)
