| Abstract: | Combined with the self-developed fieldbus NCUC-Bus protocol,a driving signal transmiter which is reliabile,high speed and easy control was designed.FPGA and the FHY chip were chosen to realize the hardware platform.And according to the requirement of the signal transition among modules and the features of the fieldbus,the servo/spindle driver which have the interface of pulse or analog was used in the communication of the fieldbus,and solved the problems of low speed,complicate control,and bad performance. |
