codes and M98, M99, M9000
～
M9999 are in the same block.
When G codes and M, S, T executed by PLC are in the same block, PLC defines M, S, T and G
to be executed simultaneously, or execute M, S ,T after G codes. Please see User Manual of machine
manufacturer for execution sequence of commands.
Execution sequence of G, M, S, T in the same block defined by GSK980TDc standard PLC
program is as follows:
M3, M4, M8, M10, M12, M32, M41, M42, M43, M44, S □□ , T □□□□ and G codes are executed
simultaneously;
M5, M9, M11, M13, M33 after G codes are executed;
M00, M01, M02, M30 after other commands of current block are executed.
1.6 Basic Axis Incremental System
The incremental system includes least input increment(input) and least command increment
(output). Least input increment is the least movement unit of programming movement distance, and
least command increment is the least unit of tool traversing on the machine. The two increment
systems use mm, inch or deg.
The basic axes include X, Z, and their incremental system has IS-B, IS-C selected by No.00.1
ISC.

In different incremental system, selecting the different axis pulse output mode can receive the
different output speed. The selection is executed by No.203 ABPx.
