1.2 Program Execution
1.2.1 Program Execution Sequence
The current program can only be run in automatic mode. GSK980MDa cannot run more than 1
program at the same time, so only one program can be performed at a time. The cursor is ahead of the
first block when a program is opened, and can be moved in EDIT mode. In automatic mode, when the
machine is in stop state, the cycle start signal ( key on the panel or external cycle start signal)
enables the program to be run from the block where the cursor is located. Usually, blocks are executed
in sequence programmed in advanced. Program stops running till M02 or M30 is executed. The cursor
moves along with program execution. The program execution sequence or state will be changed in
following conditions:

GSK980MDa Milling CNC System User Manual
Volume I Programming
z Program running stops when key or the Emergency Stop button is pressed;
Program running stops when the CNC alarm or PLC alarm occurs;
z When the system is switched in EDIT or MDI mode, program stops running after the current
block is executed. After switching to automatic mode again, when
is pressed or external cycle start signal is ON, the program runs from the block where the
cursor is located.
z If the operation mode is switched to MANUAL/MPG/STEP/MACHINE ZERO RETURN
mode when the program is running, the execution dwells; after switching to automatic mode
again, when
program runs from where it stops.
z The execution dwells when
program starts running from where it stops when
external cycle start signal is ON;
z The program dwells at the end of each block when the single block switch is on; after
pressing key or switching on external cycle signal, program continuously runs from
the next block;
z Blocks with mark “/” is skipped when the skip switch is ON.
z The object block is executed when command G65 or macro program skip (GOTO) is
specified.
z When M98 or M9000~M9999 command is performed, the corresponding subprogram or
macro program is called; M99 is executed at the end of the subprogram or macro program,
after returning to the main program, the subsequent block (the one after the block in which
the subprogram is called) is executed. (return to a specified block, if it is commanded by
M99);
z When M99 command is specified in the middle of a main program which is not called by
other programs, the current program is repeatly executed after returning to the head of the
program.

key on the panel is pressed or external cycle start signal is ON, the
key is pressed or external pause signal is cut off;

1.2.2 Word Execution Sequence within Block
When multiple words (such as G, X, Y, Z, F, R, M, S, T,) are in one block, most of M, S, and T
words are interpreted by NC and sent to PLC for processing. Other words are processed by NC
directly. M98, M99, M9000~M9999 and S word (which specify the spindle speed in r/min, m/min) are
directly processed by NC as well.
When G words share the same block with M00, M01, M02 and M30, M words are executed after
G words, and NC sends corresponding signals to PLC for processing.
When the G words share the same block with the M98, M99, M9000~M9999, these M words are
performed by NC after G words (the M signal not sent to PLC).
When G words and M, S, T words share the same block, PLC program (ladder diagram)
determines the execution consequence (executed at the same time or G words before M, S, T words).
Refer to the manual from tool builder for relevant words execution sequence.

1.3 Basic Axes Increment System
The increment system consists of the least input increment (for input) and least command
increment (for output). The least input increment is the minimum unit for programming moving
distance. The least command increment is the minimum unit for moving the tool on the machine. Both
increments are represented in mm,inches.or deg.
The basic axes herein means X, Y, Z axes. The basic increment system includes IS-B and IS-C
types which can be selected by bit ISC of parameter NO.038.
038 ISC
ISC =1：The increment system is IS-C(0.1μ)；
=0：The increment system is IS-B(1μ)
In different increment system, different pulse output type enables different output speed.
(Selected by bit ABPx of parameter NO.039)
039 ABP5 ABP4 ABPZ ABPY ABPX
ABPx =1：The impulse mode of axis is AB phases;
=0：The impulse mode of axis is impulse and direction.

As rotary axes are not involved in metric-inch interconversion, the rotation speed unit is always
deg/min.
The switch between different increment systems may cause the excess of permitted running
speed set by data parameter. Therefore, at the first power-on after switching, the system
automatically modifies relevant speed parameters and gives an alarm.
z Increment parameter
The unit and range of linear axis speed parameter are codetermined by machine tool type and
increment system.
For example: parameter NO135: X axis software limit.

1.4 Additional Axes Increment System
Volume I Programming
In the least increment system (IS-B or IS-C), under the condition that the additional axes are not
involved in simultaneous control and just used for separate motion (such as feeding), and the
requirement for precision is not high, when the least increment is 0.01, the feedrate will be much
faster, greatly increasing the efficiency. Therefore, the additional axes least increment system is not
necessary to be in accordance with the current least increment system. To meet various requirements
of users, the system adds optional function to least increment system.
Additional axes increment system is set by state parameter No.026, No.028. Shown as follows:
026 A4IS1 A4IS0 RCS4 ROS4 ROT4
A4IS1, A4IS0：Select increment system of 4th.
