Construction Lift Frequency Converter PLC HOLIP-B Manufactuer

Power range (Maximum: 415KW):

        single phase    220-240V: 0.37-2.2KW;

        three phase     220-240V: 0.37-3.7KW;

        three phase     380-480V: 0.75-75KW;

Function and Feature:

  ·  Using VVC+ vector control system, speed open-loop control accuracy is up to ±8 rpm(30 - 4000 rpm), and speed

      closed-loop control accuracy is up to ±0.15 rpm(0 - 6000 rpm);

  ·  It has closed loop speed control, closed loop process control, wobble, cascade, winding and other functions. It provides

      copy card, I/O expansion card, encoder card and other option cards which convenient the user to select corresponding

      card according to different applications;

  ·  It has excellent torque characteristic, start torque is 150% while 0.5Hz, and overload torque is 150% while 60s,180% while 1s;

  ·  It has 6 digital input terminals, which can be extended to 10 digital inputs and 4 analog inputs by I/O expansion card.

      DI4 can receive pulse signal which can be selected to work in PNP/NPN mode by setting related parameters;

  ·  It has two menus, which can be switched by communication and digital terminals, and parameters can be copied from one

      menu to the other, which can save much valuable time for users;

  ·  MCU update brings more rapid processing speed, more powerful functions. Respond speed of the communication and the

      analogue are increased greatly;

  ·  It has many protections, such as low-voltage protection, over-voltage protection, over current protection, overload protection,

      phase loss protection and other functions;

  ·  Build-in AC chock, and internal DC reactor for 18.5KW upwards,  which can mostly suppress the ratio frequency interference

      and harmonic interference;

  ·  Standard configuration of coated circuit board, to ensure the  longer service life and better reliability;

  ·  It has FC protocol and Modbus protocol, and it is easier for user to build up centralized control system.
