6.3 Coordinate System Setting

6.3.1 Coordinate System Summary

Figure 6-4 Sketch map of coordinate system

1） Reference Coordinate System

Reference point is a fixure on the machine tool. There are four reference points in all-

the first reference point, the second reference point, the third reference point and the

fourth reference point. The first reference point’s position is determined by a mechanical

switch while the others’ positions are specified by the system parameters.

Each reference point’s position parameters are as follows:

The first reference point:

P0081: X-axis first reference point

P0082: Y-axis first reference point

P0083: Z-axis first reference point

P0084: Fourth-axis first reference point

P0085: Fifth-axis first reference point

P0086: Sixth-axis first reference point

P0087: Seventh-axis first reference point

P0088: Eighth-axis first reference point

61

The first reference point’s position on machine tool is determined by the mechanical

switch. If the mechanical switch is fixed, the first reference point’s position is fixed. Due

to reference point position parameter settings are in the machine tool coordinate system,

when the first reference point’s position parameters change, its physical location does

not change and the actual change is the zero position of machine tool coordinate system.

After Power is on, executing returning the reference point in manual mode can

establish the machine tool coordinate system. Once established, it will remain the same

until cut off the power.

the position relationship between machine tool coordinate system and each reference

points is shown as figure 6-5.

6.4.1 Parameter Classification Explanation

The system parameters of this CNC can be classified three grades according to the

privilege level’s high or low:

1) Systyem Manufacturer Level: This grade parameters belong to the core parameters

which are in connection with system development. Modifying this kinds parameters

may cause system’s abnormal execution, so it needs the highest authority demand.

2) Machine Manufacturer Level: This grade parameters belong to machine tool

configuration parameters, it is modified by machine manufacturer. Its privilege level

take second place.

3) End User Level: This grade parameters are a variety parameter of the end user using.

Its privilege level is the lowest.

In the parameter setting interface, the parameters numbers of system manufacturer

level’s parameters begin with ‘S’, such as S2051; the machine tool manufacturer level’s

parameters begin with ‘M’, such as M0237; the end user level’s parameters begin with

‘U’, such as U1021.

6.4.5 Parameter’s Backup and Recovery

1、 Parameter Backup

Parameter backup means copy the system parameters and store it into the backup

storage. When needed, it can be recovered to system parameters by using parameter

recovery function. When backup parameters, the path and filename of parameter backup

can be specified by a parameter backup dialog box. If the backup path and filename are

the same, the last time backup will recover the previous backup parameters.

Method of parameter backup: [\] →[SSET] → [PARA] → [ABKP]

And then, specify the path and filename to backup parameters. Finally, press [Enter]

key to confirm.

Logic Axis Configuration Interface

Contents of logic axis configuration mainly includes several kinds as follows:

1、 Physical axis information

Physical axis information means NC system’s hardware information, includes:

1) Whether to install?: Means whether the logic aixs has the corresponding

physical axis. If the installation symbol is 0, means the logic axis doesn’t

physically assign the actual axis, namely, the logic axis hasn’t been used.

Therefore, when the installation symbol is 0, all of the logic axis’s confiuration

items are invisible ( needn’t configure).

2) Installed axis name: The name of installed physic axis, such as X, Y, Z ect.

3) Axis type: Select the usage type of the axis.

4) Installed axis

(physical): Index of the physical axis which the logic axis

corresponds to.

5) Whether has feedback?: Whether the system deals with the feedback signal

from the coder. If dealing with the feedback signal, set it as 1; or else set as 0.

2、 Display information setting
