Based on more than ten years'experience in step and Servo Research and development, ZDM-3HA2280HD has successfully developed a new type of closed-loop three-phase high-voltage stepping motor driver Thus completely overcome the open-loop stepping motor lost step problem, at the same time because of the use of three-phase high-voltage stepping motor and AC 220V direct power supply, it can obviously improve the high speed performance and torque output of the motor, reduce the heating degree of the motor and reduce the high, middle and low speed vibration of the motor, thus improve the machining speed and precision of the machine and reduce the energy consumption of the machine. In addition, in the motor continuous overload, the driver will output alarm signal, with the same reliability as AC servo system. At the same time, the motor installation size and the traditional 86-110 series stepper motor fully compatible, the traditional stepping drive program is easy to upgrade, and the cost compared with the open-loop stepper motor increase is not much, only equivalent to the traditional AC servo system 30-50% .
