BHD3278 product series is a new generation of three-phase high voltage stepping motor drive, which is designed basing on high-speed DSP + IPM DIGITAL three-phase stepper motor driver and added advanced intelligent control algorithms. Compared with ordinary DSP + IPM model, the new type has improved greatly in many aspects that includes motor adaptation, external signal adaptation, receiving pulse frequency, service life, reliability, stability, and almost without vibration or noise. This new driver is suitable for various types of three-phase hybrid stepping motor with current 7.0A below and outside diameter 57-130mm(torque range: 2NM-60NM). Position accuracy can reach the highest 6000 step/turn. This serious of products have the biggest feature of some types integrating motion control function in internal, supporting touch screen control and data input, and according to customer needs ,pre-installing punch cutting system, automatic feeding and cutting system or customized arbitrarily complex single axis motion control function.
