CNC 8070

PATH CONTROL.

Circular interpolation (G02/G03).

·160·

(REF: 1709)

Properties of the function and Influence of the reset, turning the

CNC off and of the M30 function.

• Functions G261 and G262 are modal and incompatible with each other.

• On power-up, after executing an M02 or M30, and after an emergency or reset, the CNC

assumes function G262.

Programming example.

The example shows 2 different ways to define an arc using absolute center coordinates.
