ZFeng 900 Series 630Kw-T-G General Vector Variable Frequency Drive FOR Industrial Motors

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.
