PROGRAMMING 3 BASIC CONCEPTS
6.2 BASIC CONCEPTS
6.2.1 BLOCK NUMBER AND CONDITIONAL BLOCK (BLOCK SKIP)
The block number serves to identify each block of the program.
It consists of 3 digits and it must be between 000 and 899.
A conditional block is one that is executed only when the conditional input (pin 18
of connector I/O1) is high (24 Vdc).
To define a conditional block, once the block number has been defined,
press [.] and the CNC will show at the upper display the block number
with a decimal point (period).
6.2.2 METRIC OR INCH PROGRAMMING (G70, G71)
Machine parameter "P23(8)" determines the programming units assumed by the CNC
on power-up, after executing an M30 or after an Emergency or a Reset.
Nevertheless, it is possible to modify the programming units by using these functions:
G70 Inch programming
G71 Metric programming (in millimeters)
The CNC assumes the selected units as new programming units.
The G70 and G71 functions are modal and incompatible with each other.
6.2.3 ABSOLUTE / INCREMENTAL PROGRAMMING (G90 / G91)
The coordinates of a point (position) may be absolute (G90) or incremental (G91).
When using absolute coordinates (G90), they are referred to the coordinate system
established as part zero.
When using incremental coordinates (G91), they indicate the distance to the target
point. The sign of the coordinate indicates the direction the tool must be moved to
reach the target point.
The G90 and G91 functions are modal and incompatible with each other.
On power-up, after executing an M30 or after an Emergency or a Reset, the CNC
assumes the code set by machine parameter "P21(3)". G90 if "P21(3)=0" and G91 if
"P21(3)="1"
