Warning

This system can only be operated by authorized and qualified personnel as improper

operations may cause accidents. Please carefully read this user manual before use!

Notes before operating the system:

z Connect the emergency stop button of the system firmly and correctly, otherwise an

emergency stop alarm will occur when the system is switched on, so that the system cannot work properly( it is not the system failure).

z Set the program reference point of the system according to the actual mounting position of

the tool of the machine that the system controls.

Note: The power supply of the system installed in the cabinet is exclusive to GSK’ CNC

systems.

Must not take the power supply as other uses, otherwise, there maybe cause

great accidence!

Chinese version of all technical documents in Chinese and English languages is regarded as final.

Important information.

Suggestions for safety

Ⅱ. Notes

1）Check before acceptance

Warning ● The damaged or defect product must not be used.

2）Delivery and storage

Warning ●Moistureproof measures are needed while the system is delivered and stored.

Never climb the packing box, neither stand on it, nor place heavy items on it. Do

not put over five packing boxes in piles. Take particular care of the front panel

and the display of the system.

3）Installation

Warning ●Protect the system from sunlight and raindrops. The shell of the system is not

waterproof.

Warning ●Prevent dust, corrosive air, liquid, conductors and inflammable substances

from entering the system.

●Keep the system away from inflammable and explosive substances. Avoid

places where there is powerful electromagnetic interference.

●Install the system firmly without vibration.

4）Wiring

Caution ●Only qualified persons can connect the system or check the connection. The

connecting wires cannot be damaged. Do not press or open the cover of the

system with power on.

Caution ●The voltage and the polarity of connecting plugs must accord with the user

manual.

●Wet hands are dangerous to grasp the plug or the switch.

Warning ●The connection must be proper and firm.

●The system must be earthed.

5）Debugging

Warning ●Make sure that the parameters of the system is correct before the system runs.

●No parameter is beyond the setting limit in the manual.

6）Operation

Caution ●Only qualified operators can operate the system.

●Ensure the switch is OFF before connecting the power supply.

Warning ●The operator can not leave the system to work alone.

●Do not switch on the system until making sure the connection is correct.

●The emergency stop button is able to disconnect all power supplies when the

system breaks down. Do not switch on/off the system frequently

Warning ●Prevent the system from the environmental interference.

7）Troubleshooting

Caution ●Unqualified persons cannot repair the system.

Warning ●After alarms, do not restart the system until the breakdown is fixed.

Ⅲ. Safety suggestions for programming

1） Setting a coordinate system

Incorrect coordinate system may cause the machine not to work as expected even if the

program is correct, which may injure the operator, and damage the machine as well as its

Suggestions for safety

tool and workpiece.

2） Rapid traverse (positioning)

When G00 rapid traverse performs the positioning( nonlinear motion to position between

its starting point and end point), make sure that the path for the tool is safe before

programming. The positioning is to perform the rapid traverse, and when the tool and the

workpiece are interfered, the tool, the machine and the workpiece may be damaged, and

even the operator injured.

3） Applicability of user manual

The manual introduces in detail all functions of the system, including optional functions

and max. controllable ranges, which are subject to change with the machine. If there is

any doubt, please read the instruction for the machine.

4） Functions of CNC system and machine

CNC machines depend on CNC systems, but also power voltage cabinets, servo systems,

CNC and the operator panels. It is hard to explain all the integrated functions,

programming and operation. Do not use integrated instructions not included in the manual

until they have been tested successfully.

Ⅳ. Notes and Safety Suggestions for Operating Machine

1）Test the machine without workpieces or tools. Make sure that the machine runs well before

it starts to work.

2）Check the input data of the system carefully before operating the machine. Incorrect input

data may cause the machine to work improperly, so as to damage the workpiece and the

tool, as well injure the operator.

3）Make sure that the input feedrate of the system is suitable for the expected operation.

Feedrate has a maximum for each machine, and the amount of the feed rate is subject to

change with operation. Choose the maximum according to the instructions of the machine.

Improper feedrate leads the machine to work wrongly, so as to damage the workpiece and

the tool, as well injure the operator.

4）When offset is needed, check the direction and the amount of the compensation. Improper

compensation causes the machine to work wrongly, so as to damage the workpiece and

the tool, as well injure the operator.

5）If the machine is to run in JOG working mode, check the current position of the tool and the

workpiece, and correctly specify the moving axis, moving direction and the feedrate.

MPG(Handwheel) control with great override, such as 100, may damage the machine and

its tool, even injure the operator.

6）If the tool is return to the reference point, make sure that the machine has been equipped

with the device to detect the reference point, otherwise, the tool can not reach the

VIII

reference point, which may damage the machine and its tool, and even injure the operator.

Operation Chapter Four System Operation

Chapter Four System Operation

This chapter introduces operations and notes of the system. Please read carefully before operation.

4.1 System ON/OFF, Initial State, Modal, and Safe Protection

4.1.1 Power on

There is not a power switch on the operation panel of the system. The operator installs it according to

the different machine to avoid bad effects to CNC system owing to the impaction of power supply.

Check before the system is turned on:

1) Ensure the machine state is normal;

2) Ensure the voltage meets the requirements;

3) Ensure the wiring is correct and firm.

The system is turned on as follows:

1) The master power switch of machine is turned on. Switch on the power switch of the CNC system, and the system displays as Fig. 4-1. Press

any keys except for

2) The system orderly completes the following work after power-on:

z The system controls the program loading.

z The system automatically check itself and executes the initialization.

z The system loads and checks parameters.

z I/O interface initialization.

z The system loads and checks the operator programs.

, and the system enters into EDIT working mode.

Fig. 4-1 System initialization display window

【Note】

1）Must not press any keys on the system panel when the system is turned on, press

RESET key when the system enters the press key test window at the moment.

4.1.2 Power off

The system is turned off as follows:

GSK928TEa Turning CNC System User Manual

1) The power switch of the CNC is turned off.

2) The power switch of the machine is turned off.

Check before the system is turned off:

1) X, Z, Y are in the stop state;

2) Miscellaneous function(spindle, cooling) OFF;

3) Turn off the power supply.

【Note】

1） The system should be checked itself and initialized when it is turned on firstly( it is

completed by the machine manufacturer, and the operator cannot execute the operation, otherwise, the parameter set by the machine manufacture will lose).

2） Operations related to turn off the machine power supply are referred to the operator manual

machine manufacturer.

4.1.3 System, program initial and modal

4.1.3.1 Initial and modal

The initial mode of the system is defined to be a special initial state of all functions set by itself when

the system is turned on; all auxiliary functions do not execute the actual output.

The modal of the system is defined to be their kept states after the system executes all functions.
