What to include in an overseas repair inquiry

Send the robot and controller model, the full component part number, a clear label photograph, the complete alarm message and a short description of when the fault occurs. Include your country and whether you need component inspection, repair assessment or help identifying a replacement.

Before dispatching equipment, confirm that the team can assess the exact component and agree on the receiving address, packaging, transport arrangements and inspection scope. Repair cost, parts availability and turnaround time depend on the inspection findings; an alarm code alone is not enough to confirm a repair price.

Repair, replacement or maintenance?

A failed component, an external cable problem and a mechanical load issue can produce similar symptoms. Our inquiry process starts with the available equipment records so the proposed inspection matches the fault. If replacement is considered, the part number and system compatibility still need to be checked. Planned maintenance is a separate discussion based on equipment condition and the manufacturer's maintenance schedule.

For technical reading, browse our robot repair guides and maintenance articles. To discuss equipment, send a repair inquiry or call +86 181 2200 9539.

Discuss your repair needs

Send the robot model, controller type, alarm code and a description of the fault. Our team can review the details and discuss the next steps.
