Ball mill AC drive KE300A-08 Series

three-phasedigitalvector control

KE300A-08 Series Instantaneous Stop Non-Stop Ball Mill Special Inverter KE300A-08 special inverter for instantaneous stop and non-stop, with DC bus voltage as its core control principle, using this high-performance control algorithm to maximize the utilization efficiency of DC bus voltage. After comprehensive analysis process according to the measured value of the DC bus voltage, automatically adjust the driver output state to establish a reasonable load feedback energy distribution relationships, which can maintain the drive controller without power off for 4 to 9 seconds. When the drive is completely powered off and there is no display, the power grid can automatically restart after power supply. The driver does not report a fault during the entire instantaneous power failure. Features of KE300A-08 Series Instantaneous Stop Non-Stop Ball Mill Special Inverter (1) DSP high-speed control core The control core adopts the high-speed digital processor DSP produced by TI (Texas Instruments). Ensure the system has strong performance with high speed and stability features. It can completely deal with the most complex control operations. (2) New No PG vector control technology No PG vector control can block the motion, the rated torque can up to 150% when it is 0.5Hz ; It can help to reduce the sensitivity to motor parameters and improve the adaptability at the site. It also can be applied to winding control, That's a perfect solution for multiple motors drag the same load. (3) Characteristics of "excavator" (4) Fast dynamic response The dynamic response time under PG vector control is less than 20ms. (5) Fast current limiting function
