Remarks
User macro I and II Basic variable operations, and all judgment and branch
functions are valid.
Note that the following functions are invalid.
• Macro interface input/output
• Message display and stop
• Single block stop, miscellaneous function complete
signal, WAIT suppression.
• Feed hold, feedrate override, G09 valid/invalid
• Position data Note that the end point coordinates of
the previous block are valid.
When these commands are issued, they are ignored or
illegal data is input.
(Note) When an NC alarm occurs, the alarm state will
be entered without displaying a message for
the operator.
(Note 1) Zero point return commands and start position return commands are valid, but the actual
machine movement (trace display) will differ partially from the drawing by the program
check function.
When a zero point return is carried out via the intermediate point with a G28 or G30
command, positioning to the intermediate point is in a straight line. Positioning from the
intermediate point to the zero point is carried out independently for each axis.
With the G29 command, positioning to the intermediate point is also carried out
independently for each axis.
However, drawings using program checking are always drawn with straight lines, even when
returning via the intermediate point. Thus, the path will differ partially from the trace display.
