Application Scenarios
- Used for the repair, maintenance, and spare parts replacement of machine tools, conveyors, assembly systems, and automation axes that require medium inertia and stable torque output.
- When abnormal temperature rise, operational vibration, increased noise, feedback alarms, or winding/bearing failures occur, the fault scope should be confirmed by combining alarm records, wiring checks, and component inspections.
- Before replacement, inspect the power supply, grounding, connectors, feedback loop, mechanical load, and related peripheral components.
- After installation, complete verification of power-up, communication, enable, functions, safety interlocks, and actual operation.
