PlC with the Order of the Realization of Motor Control

Programmable controller(PLC) is take the microprocessor as a core,the automatic control technology,the computer technology and the communication merges into one organic whole the brand-new industry automatic control device which develops.But at present PLC basically has substituted the traditional black-white control widely to apply in industry control each domain,often needs to stop in the practical application to the electric motor smooth start carrying on the control,this design uses the PLC control motor work using the laboratory existing resources realization,carries on to the weak electric drive strong electricity searches initially.
