DH422

Description

DH**2
Introduction
1. overview
DH**2 is the new generation high performance fully digital stepper drive which base on *2bit DSP with a advanced algorithm .the power supply range is DC*8~*6V. it can drive frame *2mm 2 phase stepper motor .
Ultra low noise and high smoothness at middle/low speed ,and high torque at high speed, which can be applied to different speed control applications. adopt smooth and accurate sinusoidal current vector control technology ,which make motor low heat .
2. features
●new generation *2bit DSP
●good smoothness ,low noise ,low heat
●build-in micro step setting
●build-in current setting
●the standstill current can be set to *0%
●opto-isolated differential pulse input
●the response frequency is up to **0KHz
●over voltage , under voltage, over current protection
3. applications
It can be used in various kinds of machines ,such as dispenser machine. floating machine
3D printer, labelling machine, medical machine, laser cut machine, and so on ,its unique features make it an ideal solution for the applications which require low noise ,low vibration, low heat and high precision
