Basic function
         1Realize the full-automatic running mode

         2 Realize the logic control and logic interlock

         3 Realize the control and lockout between the hoist andthe signal system
         4 Realize to choose the hoisting methods

         5 Realize the fault testing, alarm,protection for thehydraulic pressure, and electric equipment, etc

        6 Realize the mutual lockout and protection among thesensors
        7 Realize the mutual redundancy and lockout betweenthe hardware and software safety circuit

        8 Realize the protection and control for the hydraulicpressure system
        9 Realize the and real-time display for the hoistingspeed of the cage and the position measuring

       10 The direction memory and automatic reversingfunction
       11 The manual operation and detection running mode12 utage memoryfunction,automatic recovery thestored contents after powered on
       Feature 

       1 Realize the fullspeedup. constantfor the hoist start,speed, decelerate, and parking, etc

       2 With the high-precision torquecontrol, safely and reliably

       3 With 2 sets of PLC device, onefor operational control.and the otherfor monitor and protection.

       4 The independent PLC protectionsystem has its own power supply.the image-text display device andthe speed encoder device,it is thehoist back-up protection systemindependent from the operating system

       5 The drive control systemautomatically optimizes the parameterof the drive motor,which realize its quick response

      6 The drive system automatically makes the S-typespeed curve

      7 The digitized signal feedback ensure the controlaccuracy of the system
      8 Torgue:when running in low frequency,there’sautomatic torque promoting function, which ensure 100%limit torque
      9 The safety protection is according with all theprotection functions of the national regulations

     10 The protection is set to the independent double-lineform, and with all protection testing functions

      11 The band-type brake control function. which realizethe heavy load starting steadily

       According to the user's requirements, adding remotecontrol module,in order to realize the remote controland parameter setting, and save power about 10%-30%The system adopts the software which has won 5 itemsof the national patent. And the hardware is selected thenational famous brand production:Siemens, and EmersonPhoenix,and Omron,etc.and we adopts the Europeadvanced technology and design idea,also with bestprice and high-quality.And in2006 it has won theSmall and Mid-sized Enterprise National Innovation FundProjects .
