PE

[Function] Move along an arc originating from the current position, passing the specified position and

terminating at the end position, via arc interpolation.


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.

ARC2

100

101

Move along an arc (circular interpolation) from the current
position to position No. 101 by passing position No. 100.
