[Function] Move along an arc from the current position to the position specified in operand 2, by passing

the position specified in operand 1.

The output will turn OFF at the start of arc movement, and turn ON when the movement is

complete.

Difference from ARC2:

ARC processing resembles moving along a polygon with a PATH command, while ARC2

actually performs arc interpolation.

Select an applicable command by considering the characteristics of each command.

(Normally ARC2 is used.)

automatically based on priority speed setting), the speed set in the data at passing position 1

or speed set by a VEL command will be used (former is given priority). The speed set in the

data at passing position 2 will have no meaning.

(Note 2) If the division angle is set to a value RWKHUWKDQ³´ZLWKD'(*FRPPDQGQRUPDOGLYLVLRQ

angle), the speed specified in the target position data will be used. (The speed set by a VEL

command will become valid if position data is not specified.)

(Note 3) The acceleration is selected in the order of the acceleration in the data at passing position 1,

The deceleration will become the same value as the valid acceleration selected above.

Therefore, the deceleration in the data at passing position 1 and the acceleration/deceleration

in the data at passing position 2 will not have any meaning.

(Note 4) This command is valid on arbitrary orthogonal planes. (Axis 2 may be selected automatically

prior to axis 1 in accordance with the position data.).

(Note5) If the interval between the position origin and end position 1, or between passing position 1

and passing position 2, is small and the locus is QHDUDVRIWOLPLW³(UURU1R&7DUJHWORFXV

interval between the two adjacent positions as much as possible, setting the locus slightly

inward of the soft limit boundary, etc.

variable 2 (position 6) by passing the content of variable 1

(position 5).
