EDS2800 series inverters(frequency inverter, AC drive, AC motor drive) are special for injection molding machine which are developed independently based on EDS2000 by combining special requirement of injection molding machine line with research and development experience of our R&D Department. This series of  products have all functions of EDS2000 series and present unique exclusively-owned technologies of our company. It¡¯s mainly applied to injection molding machine energy save transformation engineering and bears good power save effect and high production efficiency. It¡¯s also used for special load which needs transient 200% overload capacity. EDS2800 particular control technology
Combine fine current vector control arithmetic with special demand from injection molding machine to the inverter which realizes fast control to torque current and fulfills high control demand from process such as high pressure molding closing¡¢plastic injection etc. to the inverter. To suppress heating of injection molding machine motor efficiently through efficient control to exciting current. Can improve work efficiency of injection molding machine by innovative control method which solves the decreasing efficiency problem when power source control is converted to variable frequency control. Overload capacity of special inverters for injection molding machine energy save is improved strongly.
EDS2800 especial reminder
We adopt simple current vector control for EDS2800 series inverters which have very strong overload capacity, so we recommend that the end-user use it in the same power as injection molding machine motor and not to amplify inverter power, otherwise have the danger of burning out the motor.
Great control function:
1. Adopt current vector control and realize full load output at low frequency (0.1Hz).
2. Super great overload capacity¡ª150% of rated current for 3 minutes, 200% of rated current for 5 seconds.
3. Perfect special control function for injection molding machine
£¨1£©This series provides two 0~1A and two 0~10V inter-isolated analog input signal channel which makes buildup for all kinds of injection molding machine control circuit more convenient.
£¨2£©Combine fine current vector control arithmetic with special demand from injection molding machine to the inverter which realizes fast control to torque current and fulfills high control demand from process such as high pressure molding closing¡¢plastic injection etc. to the inverter.
