Description
ZFeng 900 Series 630Kw-T-G General Vector Variable Frequency Drive

Variable Frequency Drive (VFD) is a power control device that applies frequency conversion technology and microelectronics technology to control AC motors by changing the frequency and voltage of the motor's working power supply.

Working Principle
  • Core components
    • Rectification: Convert alternating current into direct current.
    • Filtering: Smooth the DC voltage and reduce harmonic interference.
    • Inverter: Convert direct current into alternating current with adjustable frequency and voltage.
    • Control unit: Implement algorithm control through a microprocessor to adjust output frequency and voltage.
  • Speed regulation mechanism
    • V/f control: Maintain a constant voltage to frequency ratio to ensure stable motor magnetic flux.
    • Vector control: Independently control torque and magnetic flux to achieve high dynamic performance.
    • Direct torque control: Directly controlling torque and magnetic flux, with faster response speed.
Protection Function
  • Overcurrent protection: Monitor current to prevent overload.
  • Overvoltage protection: Monitor voltage to prevent excessive voltage.
  • Undervoltage protection: Monitor voltage to prevent low voltage.
  • Overload protection: Monitor the load to prevent motor overload.
  • Grounding protection: prevent motor grounding faults.
  • Short circuit protection: prevent output short circuit.
  • Overfrequency protection: Limit the output frequency to prevent overclocking operation.
  • Stall protection: prevents the motor from stalling during operation.
Selection And Usage Precautions
  • Key selection points
    • Load characteristics: Select the appropriate frequency converter based on the load type (constant torque, constant power, square torque).
    • Power matching: The rated power of the frequency converter should be greater than the rated power of the motor, with a margin left.
    • Environmental conditions: Consider factors such as temperature, humidity, altitude, etc., and choose a frequency converter with appropriate protection level.
  • Precautions for use
    • Installation environment: Avoid high temperature, humidity, corrosive gases, and dust.
    • Grounding and shielding: Ensure good grounding and reduce electromagnetic interference.
    • Maintenance: Regularly clean the heat sink, check cable connections to prevent overheating and loosening.
