2 Controlled Axes

2 Controlled Axes

Number of Axes (in basic configuration)

3 axes

In expanded configuration

5 additional axes (8 axes altogether)

Number of axes to be moved simultaneously

8 axes (with linear interpolation)

2.1 Names of axes

The names of controlled axes can be defined in the parameter memory. Each address can be assigned to one of the physical axes.

In the basic configuration, the names of axes

in a milling control system: X, Y and Z. The names of additional (expansion) axes

depend on their respective types.

Possible names of expansion axes performing linear motions are: U,V and W. When they are parallel to the main axes X,Y

and Z, their name will be U,V and W, respectively.

Axes performing rotational motions are termed A, B and C. The rotational axes

whose axle of rotation parallel to X, Y and Z directions are termed A, B and C,

respectively.

2.2 Unit and Increment System of Axes

The coordinate data can be specified in 8 digits. They can have signs, too. The positive sign + is omitted.

The data of input length coordinates can be specified in mm or inches. They are the units of input measures. The desired one can be selected from the program.

The path-measuring device provided on the machine can measure the position in mm or in inches. It will determine the output unit of measures, which has to be specified by the control system as a parameter. The two units of measures may not be combined on a given machine.

In the case of different input and output units of measures, the control system will automatically perform the conversion.
