NOTE

1 Previous block and running block

Since the CNC reads the block that is ahead of the
block currently being executed by the machining
program, the block being retrieved by the CNC is
normally different from that currently being
executed. The previous block indicates the block
that is ahead of the block being retrieved by the
CNC, that is, the block that is ahead of the program
block in which #4001 to #4130 are specified.

2 When variables exceeding the number of control

axes are specified, the alarm PS0115, “VARIABLE
NO. OUT OF RANGE” occurs.

[Example] O1234

;

N10 G00 X200. Y200. ;

N20 G01 X1000. Y1000. F10. ;

N50 G00 X500. Y500. ;

N60 #1 = #4001 ;

Assume that the CNC is currently executing N20. If the CNC retrieved and
processed the blocks up to N60 as shown above, the running block is N20 and
the previous block is N50. Therefore, group 1 modal information in the
running block is G01 and group 1 modal information in the previous block is
G00.
When N60 #1 = #4201, #1 = 1.
When N60 #1 = #4001, #1 = 0.

3 The block end point position (ABSIO) of the skip (G31) is the position where the

skip signal is turned on. If the skip signal is not turned on, the position is the end
position of the block.

4 "Read operation during movement is disabled" means that the accurate reading of

values during movement is not guaranteed.
