| Abstract: | In this paper, we described particularly the method that PLC controls stepping motor to accomplish orientation function in NC system, which new type PLC being able to output high-speed pulses that can avoid PLC scan cycle impacting validly, drives stepping motor to finish orientation. Moreover, this orientation method can been perfectly transplanted in other system needing accurate orientation. Therefore, the method has significance of being widely generalized. |
