Environmental & Structural Features:
- Operating Temperature: 0 to +50 °C (non-freezing)
- Operating Humidity: 85% max. (non-condensing)
- Atmosphere: No corrosive gases or dust; no exposure to water, oil or other liquids
- Motor Driver Thermal Class: 130 (B)
- Insulation Resistance: 100 MΩ or more at 500 VDC megger between case and motor windings
Working Principle: The built-in controller executes positioning, speed, and push-motion operations using a battery-free absolute encoder system. Networking is achieved via Modbus RTU over EIA-485, allowing simplified multi-axis control.
Application Scenarios: Automation systems requiring easy networking and simplified multi-axis control; operating in conjunction with AZ Series motors equipped with absolute sensors, eliminating the need for external sensors and reducing wiring.
Installation & Usage Notes: Connect using straight shielded twisted-pair cables (CAT5e or greater). Maintain ambient temperature 0–+50 °C (non-freezing) and humidity ≤85% (non-condensing). If the motor or power cable generates noise, shield the cable or apply ferrite cores. Use the MEXE02 software for configuration.
