YASNAC PCNC Programming Manual Chapter 1: Programming Basics
1.1 FUNDAMENTALS OF PROGRAMMING TERMINOLOGY
This section describes the “basic terms used in programming.
1.1.1 Numerically Controlled Axes and the Number of Simultaneously Controllable Axes
(1) Numerically Controlled Axes and Axes Names
The numerically controlled axes and the axis names are indicated in Table 1.1.1.1.
Table 1.1.1.1: Numerically Controlled Axes
(2) Number of Simultaneously Controllable Axes
With the standard specification, up to three axes can be controlled simultaneously. This num-
ber can be increased optionally to four and five axes.
(a) Number of simultaneously controllable axes with the 3-axis control function
The number of simulta.neously controllable axes is indicated in Table 1.2.
Table 1.1.1.2: The Number of Simultaneously Controllable Axes with 3-axis
Control Function
Note 1: The plane in which circular interpolation is executed is determined by the plane selection G
code (G 17 to G19) which is presently valid. For details, see 2.1.3, “Circular Interpolation
(G02, G03)”.
2: With a manual pulse generator, simultaneous control is possible in either one or three axes.
Controlled Axis Axis Name Model Name Description
Basic axes X, Y, Z
Represents the coordinate position or distance in or along an axis
indicated by X, Y, and Z.
*
4th and 5th axes
A, B, C
or
U, V, W
Represents the commands of the fourth and fifth axes. For rotary
motion, address characters A, B, and C are used and for parallel (lin-
ear) motion, address characters U, V, and W are used.
Number of Simultaneously Controllable Axes
Positioning (G00) 3 axes (X-, Y-, and Z-axis)
Linear interpolation (G01) 3 axes (X-, Y-, and Z-axis)
Circular interpolation (G02, G03) 2 axes (X- and Y-axis, Y- and Z-axis, or Z- and X-axis)
*Circle cutting (G12, G13) 2 axes (X- and Y-axis)
*Helical interpolation (G02, G03)
2 axes (circular interpolation in XY plane)
1 axis (linear interpolation, Z-axis)
See 2.1.4, “Helical Interpolation (G02, G03)”.
