Concrete block making machine starts

Concrete block making machine at boot time, the motor current is 5-6 times higher than the rated, concrete batching plant affect the life of the motor and consume more power. System was designed on the motor would have a certain selection margin, the motor speed is fixed, but in actual use, and sometimes to a lower or higher speed, frequency transformation is therefore necessary.
Inverter motor soft start can be realized by changing the frequency of the input voltage equipment energy-saving speed purposes, but also to give the device to provide overcurrent, overvoltage, overload protection function. Drive more famous domestic manufacturers have SAJ, England. Cement silo  Teng, molding machine works, the basic structure, rolling device rolling curve parameters, equipment installation accuracy and equipment installation process does not occur with the PLC man-machine interface communications, moving parts positioning approach.
