Heavy-Duty Servo Variable Frequency Drive: 5.5-800kW 3-Phase 380V, IP55 Waterproof Design

I. Core Performance Specifications

1. Power & Voltage
   • Rated Power: 5.5-800kW, suitable for medium-load equipment (e.g., conveyor belts, packaging machines, fans, pumps).
   • Input Voltage: Three-phase 380V ±15%, compatible with domestic industrial power grids and voltage fluctuation environments.
   • Output Frequency: 0–650Hz (vector control mode), meeting high-speed start/stop requirements (e.g., logistics sorting lines).
2. Protection Rating
   • IP55:
     • Dustproof: Fully prevents dust ingress, ensuring clean internal components.
     • Waterproof: Withstands low-pressure water jets from all directions (e.g., workshop cleaning, humid environments), but avoid prolonged submersion.
   • Applicable Scenarios: Water treatment plants, wastewater treatment facilities, metallurgical plants, and other industrial settings with heavy dust or moisture.
3. Control Modes
   • Sensorless Vector Control (SVC):
     • Decouples motor magnetic flux and torque for high low-speed torque output (e.g., heavy-load conveyor belt startups).
     • Dynamic response time ≤50ms, quickly suppressing overshoot (e.g., smooth restarts after emergency stops).
   • V/F Control:
     • Proportional voltage-to-frequency adjustment for fans, pumps, and other applications with relaxed speed accuracy requirements.
   • Encoder Feedback Support:
     • Enhances speed control accuracy (error ≤±0.5%) via pulse signals or encoder feedback, ideal for positioning tasks (e.g., sorting cart stop positions).

II. Key Features

1. Intelligent PID Control
   • Multi-Loop Regulation:
     • Speed Loop: Real-time correction of motor speed to counteract load fluctuations (e.g., impact from packaging machine filling stages).
     • Tension Loop: Automatically adjusts conveyor belt or rolled material tension when paired with tension sensors (error ≤±1%).
     • Position Loop: Supports pulse inputs (e.g., PLC signals) for precise positioning (accuracy ±0.01mm).
   • Adaptive Algorithm: Automatically tunes P/I/D parameters based on load changes, reducing manual debugging errors.
2. One-Click Auto-Tuning
   • User-Friendly Operation: Users select load type (constant torque/variable torque) and press "Auto-Tune" for automatic motor parameter identification (resistance, inductance, inertia) and optimal control curve generation.
   • Tuning Time: ≤2 minutes, improving efficiency by 80% compared to manual debugging.
   • Scenario Adaptability: Supports light-load (empty conveyor belts) and heavy-load (fully loaded packaging lines) startup modes.
3. Communication & Expansion Interfaces
   • Multi-Protocol Support: Built-in Modbus RTU/TCP, CANopen, EtherCAT, and other industrial protocols for seamless integration with PLCs, HMIs, or supervisory systems.
   • IO Expansion: Standard 8 digital inputs/6 digital outputs (expandable to 16) for complex logic control (e.g., multi-conveyor synchronization).
   • Analog Inputs: 4-20mA/0-10V signal compatibility with legacy sensors.

III. Typical Applications

1. Conveyor Belt Synchronization
   • Pain Point: Speed mismatches across multi-segment conveyors due to uneven loads cause material pile-ups or breakage.
   • Solution:
     • Master-Slave Control: The master VFD drives the first conveyor segment, while slave VFDs synchronize via pulse tracking or encoder feedback.
     • Dynamic Speed Adjustment: Automatically adjusts conveyor speed based on material detection sensors (e.g., photoelectric switches) for variable acceleration in sorting lines.
2. Packaging Machinery Tension Control
   • Pain Point: Rolled materials (e.g., films, label paper) are prone to breakage or slack during acceleration/deceleration.
   • Solution:
     • Install tension sensors to monitor rolled material tension in real-time. PID closed-loop control adjusts VFD output frequency to maintain constant tension (e.g., during sealing stages in bag-making machines).
     • Combine with dancer rollers for active tension compensation via torque mode.
3. Logistics Sorting Line Position Tracking
   • Pain Point: Sorting carts require precise docking at designated stations; traditional open-loop control leads to positioning errors.
   • Solution:
     • VFD receives pulse signals from PLC and uses position closed-loop control to drive servo motors for high-precision stopping (e.g., cross-belt sorters).
     • Supports S-curve acceleration/deceleration to reduce mechanical shock and extend equipment lifespan.
