Professional Quality Control Test Standard SOP
- Visual Inspection: Examine housing, PCB, terminals, connectors and labels for scratches, burn marks or component damage.
- No-load Power-On Test: Apply rated AC input, verify power LED status, no abnormal noise or overheating.
- Feedback Interface Test: Connect encoder simulator, validate feedback signal reading and position tracking accuracy.
- Closed-loop Motor Test: Run no-load motor jogging test; check stability of position, speed and torque loops.
- Communication Test: Establish RS485 / Modbus RTU connection, verify read/write of parameters and motion commands.
- Protection Simulation: Simulate overcurrent, over-temperature and feedback loss to verify fast fault trip and alarm output.
- Thermal Cycling Test: Temperature cycling from -20℃ to +60℃ for 24 hours to validate thermal stability.
- Vibration Screening Test: Simulate cabinet vibration to check solder joints and connector reliability.
- Burn-in Test: 72 hours continuous partial-load burn-in, record diagnostic logs before packaging.
New Module Installation
- Cut off cabinet main power, implement LOTO procedure and wear anti-static wristband.
- Confirm model .5-230-D matches servo motor specifications and control system BOM.
- Secure the servo drive on cabinet mounting plate, maintain required ventilation clearance around the unit.
- Wire 230VAC power, motor power cable, encoder feedback cable and 24VDC control power following official wiring diagram. Separate power cables from signal cables to reduce EMI.
- Inspect wiring continuity and insulation resistance, confirm no short circuit or reversed wiring.
- Connect RS485 communication bus, set device address and bus termination resistor.
- Restore power supply, use MMC configuration software to input motor parameters and tune servo control loops.
- Perform jog test, positioning test and cycle test; confirm no fault alarms before production operation.
