Not only with the transformation of inverter can be used to replace the complex structure of the high cost of the DC motor speed control, and drag the original from the AC motor variable frequency speed the realization of the load, will save a lot of energy, the use of PLC and inverter control can greatly reduce the links and stepless speed control to achieve, through the PLC and inverter transformation boring, boring improved performance, reduced noise, more convenient operation.
