I. Overview: HM380A constant torque angle for the other sub-type of drive, drive voltage AC110V-220V, adapter current is 8.0A less, diameter 86-130mm in the various types of three-phase hybrid stepping motor. The drive to servo motor drive principle is applied to the stepper motor drive can make the motor run smoothly, with little vibration and noise, the motor at high speed, torque and much higher than the five-phase two-phase hybrid stepping motor. The modulator is stepped sinusoidal current modulation, each step corresponds to a step motor rotation by changing the frequency of the input current drive to change the motor speed, while the output of the step number to determine the angle of the motor turn. Positioning accuracy of up to 60,000 steps / rev 
 Second, the performance characteristics: 1. Wide voltage range Input AC110-AC220. 2. The maximum response frequency of up to 200Kpps. 3.16 file segmentation options, the maximum drive current 8.0A / phase. 4. Single / double pulse function. 5. Dual subdivision switching options. 6. Input TTL signal and optical isolation. 7. With voltage, over current, overheating, short circuit, such as improving phase current protection function, high reliability. 8. Phase current protection. 9. Phase memory
