[Function] Move along a circle originating from the current position and passing positions 1 and 2, via arc

interpolation.

The rotating direction of the circle is determined by the given position data.

The diagram below describes a CW (clockwise) movement. Reversing passing positions 1 and 2 will

change the direction of movement to CCW (counterclockwise).

The speed and acceleration will take valid values based on the following priorities:

Priority Speed Acceleration (deceleration)

Setting in the position data

specified in operand 1

Setting in the position data specified in operand 1

2 Setting by VEL command Setting by ACC (DCL) command

Default acceleration in all-axis parameter No. 11

(Default deceleration in all-axis parameter No. 12)

If speed is not set, a “C88 speed specification error” will generate.

If acceleration/deceleration is not valid, a “C89 acceleration/deceleration specification error” will

generate.

(Note 1) This command is valid on arbitrary orthogonal planes. (Axis 2 may be selected automatically prior to

axis 1 in accordance with the position data.)

(Note 2) If the interval between the position origin and passing position 1 or between passing position 1 and

passing position 2 is small and the locus runs near a soft limit, “Error No. C73, “Target-locus soft limit

over” may occur. In this case, increase the interval between each pair of positions as much as possible,

set the locus slightly on the inside of the soft limit boundary, or make other corrections.

[Example] VEL 100 Set the speed to 100 mm/sec.
