System Architecture & Signal Flow
The ERCJ-CRJ3-B00-CN controller operates as the central processing and power distribution hub for the Motoman robot cell. The architecture follows a hierarchical control model:
- Host Interface Layer – Ethernet/DeviceNet connects to upstream PLC, SCADA, or MES systems for job dispatch and status reporting
- Motion Control CPU – Dedicated real-time processor executes INFORM III jobs, manages interpolation, and coordinates servo commands
- Servo Amplifier Section – Integrated or external servo drives receive PWM commands and return encoder feedback for closed-loop position control
- I/O Interface Board – Digital and analog I/O channels interface with end-effectors, safety relays, and peripheral equipment
- Teach Pendant Port – Dedicated connector for YASKAWA programming pendant enabling online/offline job editing and manual jogging
- Safety Circuit – Hardware-level emergency stop, deadman switch, and fence interlock inputs compliant with ISO 10218 robot safety standards
