Function Features

• All-in-one integrated design: onboard motion programming interpreter eliminates external motion controller hardware cost
• Built-in electronic cam, electronic gearing, position following (master-slave tracking) and segmented motion profile functions
• 17 configurable fast trigger digital inputs for home, travel limit, sensor capture, and machine interlock signals
• Full ASCII serial command protocol compatible with third-party HMI, PLC, and industrial SCADA systems via RS232/RS485
• Automatic servo loop gain tuning wizard to optimize position/velocity loop bandwidth for different mechanical load stiffness
• Comprehensive fault protection: overcurrent, overvoltage, undervoltage, over-temperature, encoder loss, travel limit overrun
• Non-volatile program memory stores complete motion sequencing logic without continuous power retention

Working Principle

1. Single-phase universal AC input rectified to DC bus voltage via internal power supply stage
2. Onboard motion CPU executes user-written G-code-style motion programs stored in Flash memory, generating target position trajectory profiles
3. Target position command compares with real-time differential encoder feedback signal to calculate position error value
4. PID servo control loop processes position error to output velocity command to internal PWM power drive stage
5. IGBT inverter converts DC bus voltage to three-phase variable frequency AC to drive permanent magnet servo motor
6. RS232/RS485 serial bus exchanges motion program upload/download, real-time position data, and fault codes with upper control equipment

Material & Structural Characteristics

• Outer Chassis: Cold-rolled steel sheet housing with matte black anti-rust powder coating
• Heat Dissipation System: Vertical aluminum alloy fin heat sink integrated on unit rear panel for passive cooling
• Control Circuit Board: Multi-layer PCB with isolated analog feedback and digital communication zones to suppress EMI noise
• Terminal Connectors: Screw terminal power block, D-Sub encoder feedback port, DB9 serial communication port
• Mounting Hardware: Two integrated metal lugs on top rear for direct cabinet panel screw fastening

Installation Requirements

1. Mount vertically on cabinet rear panel with heat sink fins exposed to unobstructed cooling airflow; reserve 80mm clearance top and bottom
2. Single-phase AC input wiring uses 1.5mm² copper cable with 16A circuit breaker upstream power protection
3. Servo motor power cables and encoder feedback cables must run in separate cable ducts with minimum 10cm separation
4. All shielded cable shielding layers terminate to cabinet grounding bar at single end only
5. Install external 24VDC power supply for limit/home switch digital input circuits as required by machine wiring schematic

Usage Precautions

• Do not run drive continuously above 70% rated 6A continuous current without cabinet forced cooling fans
• Save motion program backup file to PC storage before firmware upgrade or unit replacement
• Adjust PWM switching frequency to 8kHz for high-inductance large-frame motors to reduce switching heating loss
• Do not connect/disconnect encoder D-Sub cables under live power to avoid feedback chip damage
• Execute limit switch homing procedure after mechanical disassembly to re-establish machine absolute zero position reference
