One Axis Steppter SD-2HMA Driver + Mill Stepper Motor 57HB56
The SD-2HMA is an economical microstepping driver based on patented technology of Wantai Motor.It is suitable for driving 2-phase 4-phase hybrid stepping motors .By using the advanced bipolar constant-current shopping 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.
* The SD-2H0MA has two connectors ,P1for control signals connections,and connector P2 for power and motor connections .The following tables are brief descriptions of the two connectors of the SD-2H044MA.More Detailed descriptions of the pins and related issues are presented in section 7,8,9.
Suitable for a wide range of stepping motors from Nema size to ,It can be used in various kinds of machines ,such as tables ,labeling machines ,laser cutters,engraving machines,pick-place devices ,and so on .Particularly adapt to the applications desired with low vibration,high speed and high precision.
6.Selecting Supply Voltage
The power MOSEFTS inside the SD-2H044MA can actually operate within18V +45VDC
,including power input fluctuation and back EMF voltage generated by motor coils during motor shaft deceleration.Higher supply voltage can increase motor torque at higher speeds ,thus helpful for avoiding losing steps.however,higher voltage may cause bigger motor vibration at lower speed ,and it may also cause over-voltage protection or even driver damage .Therefore,it is suggested to choose only sufficiently high supply voltage for intended applications,and it is suggested go use power supplies with theoretical output voltage of +18V~+45V,leaving room for power fluctuation and back-EMF.
7.Selecting Microstep Resolution and Driver Output Current
This driver uses an 8-bit DIP switch to set microstep resolution.and motor operating current,as shown below:
Supply voltage 24VDC up to +45VDC
