The stepping in this design dynamo drives the control system regard complicated programmable logic device, PLD in CPLD as the nucleus because of adopting the device of CPLD, synthesizing several modules of the stepping dynamo controller together, the function is strong and big, and whole hardware structure very Chien's , saved the resource.Pass the MAX+plus Ⅱ system development software makes the device of CPLD oneself of in ass- -ociation with the test set( JTAG) connecting orifice proceeds with the machine of PC string row connecting orifice the communication, the different work status that can aim at the different type stepping dynamo proceeds the on-line the programming of system, modification with enlarge the function, making controller of the reliability is higher with the stability, operating more vivid, because of characteristics of oneself the device of CPLD, can also control several steppings dynamo at the same time, also have good application to synchronous control system in dynamo in many steppings value.
