2.2 AXIS NAME
Names of axes can be optionally selected from X, Y, Z, A, B, C, U, V,
and W. They can be set by parameter No. 1020.
Explanation
- Axis name expansion function
With the optional axis name expansion function, I, J, K, and E can also
be used as axis names.
When I, J, K, and E are used as the names of axes, these addresses have
the following functions and restrictions:
(1) These addresses are addresses for coordinate words.
Example) G17I-K- ; The I-K plane is selected.
(2) The numeric values to be specified must consist of up to 8 digits.
(3) A decimal point can be input.
If a decimal point is omitted, its position is determined according to
the increment system of the axis for that address.
Example) G00 E0.5 I 100 K 100.0;
(4) A signed value can be input.
Example) G01 E-10.5 F100;
Limitation
- Axis name expansion function
- When I, J, K, and E are used as axis names, they cannot be used
for the ordinary purposes listed below.
