Warning！
zBefore installing, connecting, programming and operating, please carefully read
the product user manual and the manual from the machine tool manufacturer and
strictly operate accordance with the regulations in the manual; otherwise, the
product or the machine tool may be damaged, the workpiece may get rejected,
even the personal injury may occur.
Caution！
zFunctions, technical indexes (such as precision and speed) described in this user
manual are only for this system. Actual function deployment and technical
performance of the machine tool are designed by the machine tool manufacturer,
so function configuration and technical indexes are subject to the user manual
from the machine tool manufacturer.
zThe system is with the standard machine operation panel, but the function of each
button on the machine panel is defined by the PLC program (ladder diagram).
Please pay attention to that the function of the buttons in the manual is described
based on the standard PLC programs!
zRefer to the user manual from the machine tool manufacturer for function and
meaning of each button on the machine panel.
Announcement
zThis manual describes various possibilities as much as possible. However,
operations allowable or unallowable cannot be explained one by one due to so
many possibilities that may involve with, so the contents that are not specially
stated in this manual shall be considered as unallowable.

CHAPTER 1 PROGRAMMING
1.1 GSK980TDi Introduction
1.1.1 Product Introduction
Being upgraded product of GSK980TDi, GSK980TDi CNC turning is the better choice.
The updated development GSK980TDi Turning Machine CNC System made by GSK CNC
EQUIPMENT CO., LTD. is the new product based upon the GSK980TDi updated software/hardware,
which owns the vertical and horizontal structures. GSK980TDi uses the GSKLINK bus technology,
matches with the 17bit absolute encoder, carries out the automatic recovery of the system power-on,
no-block mechanical zero return, servo parameter on-line modification or servo state on-line
diagnosis, etc.
.
GSK980TDi GSK980TDi-V
5 feed axes，2 analogy spindle
control precision 0.1μm，Max. speed 120m/min
GSK980TDi standard configuration with GS2000T-LA1 series strong overloading servo unit, it
is used the GSKLINK bus technology, matched with 17Bit absolute encoder
The spindle orientation can be carried out by adapting the servo spindle, Rigid tapping,
Cylindrical Interpolation or Polar Coordinate Interpolation.
Used the GSKLINK bus technology ，carried out the functions such as the power-on
automatically recover of the coordinate system, Non-block mechanical zero return, Servo
parameter on-line modification and servo state on-line diagnosis, etc.
Built-in multi PLC programs，PLC ladder on-line display and real time monitor, as well the
series I/O unit.
It owns the MPG trial cutting, Teachine, MPG interruption functions.
It owns the functions, such as the on-line machine tool debugging guide, miscellaneous
programming, diagram dimension directly input and polygon turning, etc.
MDI multi-block performance
