Working Principle: Motion program stored in onboard memory runs independently after power up. Controller generates motion profile for each axis and sends command signals to external servo amplifiers. Encoders return real-time position feedback. DSP executes closed-loop PID calculation for every axis to minimize position error. Digital I/O captures sensor signals and triggers motion actions. All motion data can be uploaded to PC via Ethernet for analysis.
Installation Requirements:
- Mount inside ventilated electrical cabinet
- Reserve clearance for heat dissipation
- Use shielded differential cables for encoder and command signals
- Route signal cables separately from high power motor cables
- Implement reliable protective grounding
Usage Notes:
- Configure axis mapping and encoder parameters before commissioning
- Perform PID auto-tuning for each axis to optimize dynamic performance
- Save complete program and parameter backup
- Do not exceed maximum 80V DC supply voltage
- Cut off power supply before opening enclosure
