1. Equipment Overview
Automatic Wiring Harness
• Function: Winds three wire strands together, improving wiring harness processing efficiency.
• Core Drive: An integrated brushless motor (BLM4205B-485-0FS) paired with a host computer (QT) and a pulley drive system.
• Quantity: One motor per unit.
2. Application Solution
1. Control Mode:
PP Mode (Position Control): Ensures precise winding position.
PV Mode (Velocity Control): Optimizes the dynamic response of the winding process.
2. System Architecture:
The motor communicates with the host computer via 485 communication, allowing real-time adjustment of operating parameters.
The pulley drive assembly transmits power and must match the motor's torque characteristics.
