I've the arm and controller identifiers plus a photo of the arm connection cable. The drawing doesn't match, and the manual filename gives no controller configuration.

Put those together in a short request for the applicable document and confirmation of its configuration. Keep the setup off while connection identity is uncertain.

Worth trying the maker directly? 'Checking with engineering' is all I'm getting from the seller.

@LucyAli0219 Try a contact you can verify through the maker's published information. Ask whether they can identify the document; don't assume that means they'll take over seller support.

@LucyAli0219 Because the equipment labels match your order, the wrong manual seems to be the issue. Request the configuration guide that belongs with the package you received.

A manual mix-up could explain it, but the labels alone don't establish that the interface is right. The configuration still needs confirmation.

Agreed, my wording was too definite. The request should cover the hardware configuration as well as the matching document, not merely a replacement file.

@SamBell0681 Could a manual name the correct robot model while its instructions don't apply to the supplied controller?

A matching robot name doesn't confirm every diagram. The document also needs to cover the controller and configuration shown by your equipment identifiers.

@SamBell0681 That's exactly what I can't establish. Our equipment labels are readable; the file doesn't link the illustrated connections to our controller.
