AC Variable Frequency Drive (VFD) 1HP-10HP 220V/380V - Detailed English Translation

I. Product Overview

This product is a 1HP-10HP Vector Control Frequency Inverter supporting 220V (single/three-phase) and 380V (three-phase) input voltages. It is designed for industrial applications such as pumps and fans, offering high-precision vector controlenergy efficiency, and comprehensive overload protection.

II. Core Parameters & Performance

  1. Power & Current Matching
    • Power Range: 1HP (0.75kW) to 10HP (7.5kW), suitable for small to medium-sized motors.
    • Output Current:
      • 220V Input: 4A (1HP), 9.6A (3HP).
      • 380V Input: 2.1A (1HP), 17A (10HP).
    • Selection Principle: Base selection on motor operating current. For heavy-duty applications (e.g., cranes), choose G-type drives with 2-3 power ratings.
  2. Control Method
    • Vector Control (Open/Closed Loop):
      • High Starting Torque: Stable torque at low frequencies (e.g., 180% rated torque at 0.25Hz).
      • Wide Speed Range: Speed regulation ratio up to 1:100 for precision applications (e.g., CNC machines, printing presses).
      • Fast Dynamic Response: Rapid speed adjustment under load changes.
  3. Energy Efficiency
    • Principle: Adjusts motor speed to match load demands, avoiding energy waste from throttling (e.g., valves/dampers).
    • Case Studies:
      • Steel Industry: 38% annual energy savings after retrofitting rolling mills.
      • Municipal Water Supply: 20% energy reduction with control and reduced pipeline burst risks.
      • Port Cranes: 40% energy savings per unit, recovering 120,000 kWh annually.

III. Overload Protection

  1. Inverse Time Overload Protection
    • Mechanism: Simulates motor thermal characteristics using an electronic thermal relay. Protection time decreases as current exceeds rated values.
    • Setting: Adjustable threshold (e.g., 120% of rated current) with customizable overload curves.
  2. Overcurrent Protection
    • Instantaneous Detection: Immediate output cutoff during short circuits (far exceeding rated current).
    • Application: Prevents damage during motor internal/output short circuits.
  3. Other Protections
    • Voltage Protection: Safeguards against undervoltage/overvoltage conditions.
    • Short Circuit Protection: Rapid fault isolation.
    • Thermal Protection: Temperature sensors monitor internal heat, triggering derating or shutdown.

IV. Selection Guidelines

  1. Load Type Matching
    • Constant Torque Loads (e.g., cranes): Use G-type drives with 2-3 power ratings.
    • Variable Torque Loads (e.g., fans/pumps): Select P-type drives equal to motor capacity.
    • Special Loads (e.g., synchronous motors): Increase drive capacity by 10-20%.
  2. Environmental Adaptability
    • Temperature/Altitude: Derate if ambient temperature >40°C or altitude >1000m.
    • Protection Class: IP55+ for dusty/humid environments.
    • Installation Distance: Reduce carrier frequency or add output reactors if drive-motor distance >50m.
  3. Special Requirements
    • Multi-Motor Drives: Add thermal relays per motor; VFD control limited to V/F mode.
    • Long-Distance Transmission: Lower carrier frequency or install output reactors.

V. Installation & Commissioning Notes

  1. Carrier Frequency: Automatically reduce at low speeds to minimize electromagnetic interference.
  2. Resonance Avoidance: Use frequency skip function to bypass mechanical resonance points.
  3. Braking Unit: Required for heavy-load descending or high-speed braking; enables energy recovery.
  4. Parameter Optimization: Adjust PID settings, acceleration/deceleration times based on load characteristics.
