Product Description

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.
