Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

Tested with a DRP-240-24, and is OK.
This PS can handle this.
I will use two of these in parallel, with ~ 100.000 mikrofarads, so that the voltage would never drop.

Hi @RufusDufus please have a look at www.xsimulator.net/community/threads/3rd-axis-second-interface-no-connection.5966/ perhaps I have run into a SMC3 related issue? Thank you very much in advance.

It occurred to me at all. But it works. Thank you.

Why am I writing in SMCulits that the engines are off? All I got involved in Scheme MODE2. I use 24V wiper motors.

@berty, SMC3 has automatically disabled the motors because the feedback position is outside the limit zone (ie the green line is outside the outside red limit lines on the chart) This is a safety feature to prevent damage.

Make sure your POTs are somewhere in the middle of the range before switching the arduino on. (Or you should be able to move the POTs back to the middle by checking the graph and then clicking the OFF button next to the motor)

Okey. Thanks for your help. They are now ON. But when I want to be moved, set Out Mode, the engines are not moving at all. Why?

is your potentiometer connected to your motor? it should be so motors can move if not turn it by hand to see what motor is doing, but you have to follow the steps described here first http://www.xsimulator.net/community...3dof-motor-driver-and-windows-utilities.4957/

Yes, I have it connected correctly. Motor1 me a moment goes, then I switch the Motor2 let run for a while, then switch back to Motor1 and suddenly does not work.

So the problem is solved. I had a lot of erroneous values in SMC3Ulits. I would still ask how it is possible to accelerate the engine? What needs to be set?

PWMmax 240 and Kp 500...

Thank you very much. Moment burned one H-bridge. Interestingly, just one that did not move, but never mind replace it and be fine.

Okay. H-bridge replaced everything works, but when I try in simtools Outputtesting, so in the middle does not move. (red box-nothing happens, the green field- engine responds.) Why?

There is quite a bit of discussion around this in posts 347-363 of this thread on pages 18 and 19...

The short term solution that has worked for most people was found by @Jymä:

"Got it working!!! Apparently it is a little bug or incompability in SimTools (or with SMC3 communication). I had the same thing with one other program. Though SimTools worked well with another Arduino code.

If I have Finnish date and time format in windows (the bottom right clock shows now 9:41 18.10.2014) that problem occurs. If I change it to English (9:41 18/10/2014) it starts working! It can be tested by going to Control Panel->Clock, Language, and Region->Change the date, time or number format and put it to Finnish. And then launching SimTools again. Thank you for this motor driver!"

Hope it solves your issue also.

The next release of Simtools will have a fix. The reason for the problem is noted in, post 363.

Wuaaw, it's working. Thank you very much. I noticed that there is already such a problem is solved. Thank you again.

As regards those of my H-bridge. They can be connected in parallel to each other? Because I have a pretty big engines and I am afraid that I was burned others.

Just found this post; since I'm having ad arduino UNO delivered on monday, I think I'll follow these steps.
Thanks!!

According to the non existent specs I would not connect them in parallel mode. Furthermore these bridges are not recommended IMO. I had run into many issues using them.

What problems did you have? I have none so far [for a few days] on 24Volts.
[not in parallel]

Specs for the IBT-2:

I just left (top) while the engine is not run for long.
