Five photographs and a fault code can save days of back-and-forth. Here is what service engineers actually need from your equipment.
When a service team receives a request, the first questions are always the same: what is the equipment, exactly, and what is it doing? Most of the answers live on the nameplate — the rating label fixed to the drive — and in the fault display. Capturing them well up front shortens every step that follows: triage, parts identification, and the decision between on-site work and workshop repair.
What to capture from the nameplate
- —Brand and product series — e.g. the family name printed largest on the label.
- —Exact model / type code — the full string, not an abbreviation; one character can distinguish voltage classes.
- —Rated power and rated input/output voltage and current.
- —Serial number — needed for manufacturer records and parts traceability.
- —Any option or configuration codes printed near the type code.
Beyond the nameplate
- —The exact fault code shown on the display or keypad, and the sequence if several appear.
- —When the fault occurs: at power-up, at start command, under load, randomly.
- —What changed recently: new load behavior, electrical work, environment changes, storms.
- —Photos of the installation — the cabinet, cable entries, cooling path and surroundings tell an engineer more than most descriptions.
Photograph tips
- —Shoot the nameplate straight-on, in focus, with the whole label in frame.
- —Include one wider shot showing the drive in its cabinet.
- —If the display shows a fault, photograph it before resetting anything.
DUCHENG’s service request form asks for exactly these details — brand, model, power/voltage and fault code — because they are what lets an engineer prepare properly before contacting you.
