Compared with the traditional inverter ball mill drive control system, the KE300A "ball mill" special inverter has made advanced current limiting technology and hardware optimization design for the starting characteristics of the ball mill, adjust the current and the power supply voltage of the motor in time and accurately. Through the dynamic tracking optimization control algorithm, makes the output power of the motor accurately match the load and realizes the dynamic tracking energy-saving control of the load of the ball mill. The user does not need to make many complicated settings when using it. You just need to make simple parameter modification according to the actual use site.
(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.
