3. Interface Layout & Core Functions

Main Connectors

1. CN1 (15Pin Omron control port): Receives open-collector/differential pulse position command(max input frequency 500kpps, adjustable electronic gear ratio) and ±10VDC analog signal for speed/torque control; built-in multi-channel DI/DO for servo enable, travel limit, fault reset and alarm output signals.

2. CN2: Dedicated encoder feedback port to realize full closed-loop high-precision position control.

3. CN3 RS232 debugging port: Connects with SigmaWin software for parameter editing, auto gain tuning and real-time running status monitoring.

Core Advantages

1. Flexible switching among Position / Speed / Torque three control modes via internal parameters for diversified automatic equipment demands.

2. Built-in automatic motor parameter identification and online adaptive gain auto-tuning, greatly shortening on-site commissioning time.

3. Multi-order mechanical notch filter to suppress equipment resonance, reduce vibration and improve positioning accuracy.

4. Full-range protection functions: overcurrent, overvoltage, undervoltage, overload, overheat, overspeed, encoder disconnection protection; front panel LED fault code display for rapid failure troubleshooting.
