Check whether a problem has arisen in the offset of the P.E.C.

recognition camera. *5

If the offset has a problem, it will result in overall positional devia-

tion of placement.

Confirm that there is no problem in the offset of the P.E.C. recogni-

tion camera.

Note: Although the offset data of the P.E.C. recognition camera can

be taught at the “OFFSET TEACH” display, it is required to

re-teach a series of device offset data. (Hierarchical Sequence:

“SPECIAL SEL.” Display → “OFFSET TEACH” Display)

A special jig is also required for the teaching operations.

Whenever it is necessary to perform the teaching operations,

consult our sales personnel for details.
