[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)
1
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
3
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) This command is valid on arbitrary orthogonal planes. (Axis 2 may be selected automatically
prior to axis 1 in accordance with the position data.)
[Example] VEL 100 Set the speed to 100 mm/s.
