Hello!

I'm using LINIX Stepper Motor 57BYGHD451 with 6.0kg.cm holding torque. I would appreciate if anyone can send me example program of microstepping with the driver (SJ-230M2).

Thank you.

Never use a 5-phase stepper motor. Anyway, do u have the datasheet?

Yes, i have the datasheet but it only show how's the driver works and the pins connection. I have enough about the theory and now I need to find some sample coding of microstepping. :oops: :oops:

Searching Internet, that model showing Chinese Character of Datasheet/User's Manual. :?

Microstepping is normally being set through single pin, serial protocol or preset using DIP switch. If that driver does not provide serial interface, so only left pin or DIP switch. Does the driver come with that? If the driver do not offer microstepping at all.... software from host cannot do it. It must come from driver site. :D

Oh yes, you are correct! :P

Through the datasheet, it says that subdivision setting were done by DIP switch.
Is it mean that, if i followed the setting, i dont need to programm it in the compiler? Then, how am i going to prove that the motor were actually move 1.8 deg per step?

Hi, actually to know whether it is 1.8 degree per step or any degree per step, drive it step by step.

Put a marker on the stepper motor shaft, just draw a tiny straight line through the shaft center point. Put the line 90 degree or 0 degree where you can refer it easily.

Try driving it step by step and count your step. Stop when the marker(shaft) have already make a complete rotation. Now the steps you have used to drive stepper are 360 degree, a complete rotation, right? Let's say is 200 steps. So, step angle (degree/step) is ? 360 degree / 200 steps = 1.8 :shock:

If you have successfully configure it to be micro-step, depends on which ratio, apply same concept! Good luck and do share with us the progress.

Hello Mr Choo,

Thank you for the tips! Because of the motor come with a gearhead (LINIX 60JB10G0832) so I guess I can't follow the tips right? Well, I assume the step angle (degree/step) is 360 degree / 200 steps = 1.8 then! :roll:

Actually you still can implement the trick if you know the gear ratio of the gearbox. Just some simple calculation to get the answer.

Agreed with sich, you can still apply the trick if you have the gear ratio, normally it should be something like 5:1, 10:1, 30:1, 50:1, 100:1, etc. Apply the same concept divide more step. Definately, the steps to get a complete rotation will be more.

Even you don have the gear ratio, it is still possible to get the closest step angle. Because you can try to apply a few common gear ratio and look at the step angle you get, if the step angle is weird figure, try another gear ratio.
