stepping motor driver(SD-2H086MB)

Introduction
The SD-2H086MB is an economical micro step driver. It is suitable for driving 2-phase 4-phase hybrid stepping motors. By using the advanced bipolar constant-current chopping technique, it can output more speed and torque from the same motor, compared with traditional drivers, such as L/R drivers. Its 3-state current control technology allows coil currents to be well controlled and with relatively small current ripple, therefore less motor heating is achieved.

Features
1)Low cost and good high-speed torque
2)14 selectable resolutions
3)Supply voltage up to +80VDC
4)Suitable for-2-phase and 4-phase motors
5)Output current up to 5.86A
6)Dip switch current setting 8 different values
7)Optically isolated input signals
8)Pulse frequency up to 200KHz
9)Automatic idle-current reduction
10)Small size (151*107*48), Weight: 1KG
