Prepare a drive model, board or fault investigation request
The best repair record starts with exact evidence: nameplate identity, fault timing, board markings and the machine condition when the symptom appears.
Evidence to provide
- Manufacturer and complete drive model number from the nameplate.
- Input voltage class, power rating, frame size and application.
- Fault code, keypad message, LED indication or no-display symptom.
- Whether failure occurs at power-up, enable/run command, acceleration, deceleration, stopping or under load.
- Whether the motor and cable were connected when the symptom appeared.
- Visible board, module, connector and option-card identifiers.
- Clear photos of the label and affected assembly, excluding confidential plant information.
Request brief template
Drive brand and model:
Input voltage and power rating:
Exact fault text or symptom:
When it happens:
Motor/cable connected:
Recent repair or replacement:
Board or module markings:

Use this template before contacting a repair desk, OEM support channel or internal maintenance team. A complete request reduces repeated clarification and helps identify the correct model, board, circuit or diagnostic record.
Good requests become reusable service records
IndustrialDriveData is organized around evidence that can be reused: exact model identity, fault timing, board markings, circuit path and a diagnostic workflow that another technician can follow.
High-value examples include ACS800 PPCC LINK, Siemens 6SE70 DC-link faults, VFD no display, overcurrent at startup, DC bus overvoltage during deceleration and repeated IGBT module failure after repair.
Safety boundary
Records published by IndustrialDriveData provide technical reference and diagnostic context for qualified personnel. They are not a substitute for site safety procedures, OEM service approval, lockout procedure or live-measurement training.
Industrial drives may contain lethal input, DC-link and output-stage voltages even when the display is off.
