Working Principle: The controller executes stored motion program and generates motion profiles for each axis. Command signals transmit to external servo drives. Encoders feed back real-time motor position. DSP runs high speed PID algorithm to reduce position error. Digital I/O channels collect field sensor signals and trigger motion events. Communication ports enable connection to upper monitoring system.
Installation Requirements:
- Install inside protected electrical cabinet
- Avoid direct exposure to dust, moisture and vibration sources
- Use shielded cables for encoder and command signal wiring
- Separate low voltage signal wiring from high power cables
- Complete reliable protective grounding
Usage Notes:
- Confirm power supply voltage within 12-24V DC range
- Set encoder resolution and motor parameters before startup
- Tune PID parameters for each axis according to mechanical load
- Backup motion program and parameters
- Disconnect power before wiring modification
