Understand this reference
Application and identification
The retained listing identifies KGN-M5840-040 as a Yamaha servo board assembly and names YG200 in its heading. It does not document firmware, configuration data, an approved revision substitution or an operating test for the board offered to a buyer. The photograph shows a circuit-board reference; it cannot establish those hidden conditions. Keep the assembly code and readable labels from the installed board together with the machine/control-system identity so the quotation concerns a specific replacement requirement.
02 / Check before ordering
Match the installed part
The family page groups related variants; it does not imply that variants are interchangeable.
- Record the exact KGN-M5840-040 label and all revision or configuration labels without dropping suffixes.
- Ask the responsible service team which machine/controller documents establish the replacement and configuration requirements.
- Compare repair versus replacement using an agreed evidence and return scope, rather than an unsupported claim that the board is plug-and-play.
03 / Make a useful decision
Selection and replacement advice
A replacement board, repair of the installed board and purchase of an untested spare have different acceptance needs. Ask a service technician to document the fault diagnosis and the basis for selecting the board before comparing those options. For a replacement, request revision-label and connector photographs, the declared configuration state and the scope of any proposed test. A power-on photo alone does not establish correct operation in the intended control system. Do not assume a board with the same connector arrangement has the same firmware or wiring.
04 / Care and handling
Maintenance and handling guidance
Preserve the original fault description, board labels and configuration records before a service intervention. Maintenance and electrical work must follow the applicable equipment/service procedure; this page is not a live-board repair instruction.
Ask for the board's handling, storage and protective-packaging requirements and evidence of prior repair if declared. The listing does not establish an antistatic acceptance test, storage lifetime, firmware backup method or safe universal cleaning procedure.

Questions about this family
What establishes the ordering identity?
The source-listed codes and distinctions are retained above. Require the applicable machine documents and readable offered-item labels to resolve revisions and installed fit.
Does the photograph prove stock, condition or authenticity?
No. The photograph is a catalogue reference, with any visible limitations disclosed. Ask for evidence of the actual item, its declared maker and condition, and the agreed inspection scope.
Can another variant be substituted?
No substitution approval is given. The required application, interfaces, revision and acceptance basis must be established for the actual machine before an alternative is accepted.
