  • V6-H Series VFD Drive Frequently Ask Questions About Debugging
    • August 17. 2021

    I.Why occur over current trip or over load trip in vector control 2 with encoder speed feedback? Check the parameter settings: (1)Check if the motor parameters are properly set (2)Check if the encoder pulse Pd.21 is properly set (3)Check if the encoder direction parameter of Pd.22 is properly set (4)Check if the ratio between motor and encoder Pd.24 is properly set Check the hardware connection (1...

  • how does a ac drive control speed
    • August 19. 2021

    The ac drive controls the speed of the pump and fan by changing the electrical energy supplied rather than damping the air- or water flow. It is like reducing the speed of a car by pressing less on the accelerator instead of using the brake to slow down the speed. The payback time of an ac drive is typically one year or less. Other benefits of using ac drive to control the speed of fan or pump are...

  • What are the applications of AC drive?
    • August 24. 2021

    Drives are widely used in manufacturing industries to regulate and control rotating equipment such as fans, conveyors, machine spindles, and pumps, which are used in production processes. AC drives are widely used in process industries to increase the efficiency of equipment. It controls the speed of electric motors according to the process needs, typically reduces energy consumption by 35-40%. Ho...

  • Variable Frequency Drive VS Variable Speed Drive
    • August 26. 2021

    In modern industries, electric motors are playing a important role in modern technology. In an effort to decrease electric motor energy consumption in these energy-hungry devices―and optimize their efficiency―manufacturers have employed various drive-technologies to modify the motors' speed. These technologies, which include universal variable frequency drives (VFD, AC Drive Converter) and variabl...

  • Can I put a VFD on any motor?
    • August 30. 2021

    When a variable frequency drive (VFD) is added to an existing system, many potential problems may arise. Reduced cooling at reduced speed Most motors running across the line depend on an internal, shaft-driven fan for cooling. When the motor is operated with a VFD, the motor shaft speed (motor speed) decreases and will cause decreased cooling from the shaft-driven fan. If the load is a standard va...

  • What is the difference between a soft starter and a VFD (variable frequency drive) for electric motors?
    • September 03. 2021

    The major difference between soft starter and VFD are as follows. 1. Soft starter is used to start and stop the motor smoothly., without jerk load. 2. The starting torque delivering capacity of the soft starter is poor as V/f ratio or the flux is much lower than the rated capacity of the motor flux. It is suitable for the driven equipment which start at almost no load. 3. VFD is also soft start an...
