IV. SYSTEM OPERATION
In this chapter, details the all functions modules of this GSK928TC turning CNC system and their operations
and notices. Please read this chapter carefully before start the machine with this system.
4.1 System turn on/off
There has not the power switch on this system. To avoid the power concussion, install the power switch for
this system according to the actual state of the machine.
Turn on as follows:
1Power on the machine’s electrical source first.
2Put through the system’s switch if there has, and then the system appears as picture1. Keep pushing any
button with the exception of the buttons , , when it is displaying the picture1, the
system will display the version number of this system. After release the button, the system enters the
normal run state.
Turn off as follows:
1Cut off the system’s switch if there has.
2Power off the machine’s electrical source.
CAUTION: When the system powers on first, it is needed usually to operate as follows:
1. Initialize the system’s parameter section such as:
Push the button and at the same time . First release the button , after 3 seconds, release the
button , the system was initialized. At then, all the parameters of tool offset are 0, all the parameters of the
machine reset as initial value. Please consult the offset and parameter instruction in this manual.
2. Measure the reverse transmission clearance of X, Z axes, and enter system parameters P07 and P08. Please consult
the parameters instruction in this manual.
3. Define the DIRZ and DIRX in parameter P11 according to the electric design and motor direction of the machine.
4. Adjust the parameters P05, P06, P17~P22 to let the machine run reposefully and availably according to the
machine’s load.

Cautions:
1. When the cutting program is sent from the external pc to this system, this system makes the program name with
the character string ‘%xx” in the first row. If the name of the received program is same as the stored program,
the name and contents of the received program can’t be displayed. So the stored program with same name must
be deleted first before check the new program.
2.
All the cutting programs can be exchanged as above method between GSK928TC systems. Just operate two
GSK928TC systems with input/output mode.

and so on. Only correctly input the contents of the cutting program in the light of the cutting technics, the
system can run normally.
The edit model of this system is full screen. The programs are managed as documents.

Every program consists of some program segment. And each segement begans at N**** . After a
new program is built, the system will create the first serial numbe as N0000 . And when push button
Enter after inputted a segment, the system will create the next serial number automatically. The increment of
the serial number in program input is set by the parameter P23. The parameter P23 can create the serial
number with the integer of the 1/4 increment.
Create the serial number of segment as PICTURE 8 (Parameter P16 is 10):
