CIRT – Circular Interpolation (Helix)
The CIRT command is similar to the CIR command, with the addition of interpolation with a third axis to perform a helical or tangential type movement. CIRT is a write-only command and can only be used for a circular interpolation between the X and Y axes, with the Z axis used for linear coordination. Circles can be drawn in either the CW or CCW direction. All CIRT moves are interpreted as absolute moves.
Applies to: CMD-4CR, CMD-4EX-SA
ASCII/Standalone CIRT
Syntax
Write
CIRTN[C1]:[C2]:[Z target] * for CCW motion
CIRTP[C1]:[C2]:[Z target] * for CW motion
|
Where: N is CCW motion, P is CW motion, [C1]:[C2] specifies the circle coordinate center of X, Y axes (32-bit value), [Z target] specifies the target position for the Z-axis (32-bit value) |
