4.8 Axes Programmable by Diameter and Internal Measurement P4
Description
4 - 18 en-938818/7
Category Axis declaration
Type 0 8-bit hexadecimal
No. of words 5
Used to:
- declare the X and U axes of each group as programmable by diameter,
- define the internal system measurement unit,
- specify that control of the X and/or U axes of each group is referenced to the diameter in incremental JOG mode
and handwheel mode (including NMauto),
- specify the divider for the rotary axes.
Principle
Each bit of words N0 and N1 represents the address of an axis group.

Word N0: characterises the X axes of the different axis groups.
If the bit is a 1, the X axis for the group specified is always displayed by diameter and is programmed by diameter for
turning (G20 state).
Word N1: characterises the U axes of the different axis groups.
If the bit is a 1, the U axis for the group specified is always displayed by diameter and is programmed by diameter for
turning (G20 state).
Word N2: defines the internal system measurement units.
The value entered sets the number of digits after the decimal point. The basic unit is the mm. The internal
measurement units directly affect the machine travels.
