PE

[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)

(Note1)

This command is valid on arbitrary orthogonal planes. (Axis 2 may be selected automatically
prior to axis 1 in accordance with the position data.)
