Arduino uno with Rhino controller and RMCS-1001 stepper Motor connections

Dear Team,

I Have a legacy system which consists of Arduino Uno, Rhino Motion controller with Stepper motor (RMCS-1001), we are facing an issue in the following

  1. we cannot able to achieve the exact steps. when we give 200 steps to move it is not completing the exact 200 steps.

  2. Abnormal vibration found on the stepper motor.

  3. Need some help in the code also.

Anyone available to help us, we are in need of help.

Are the achieved steps always less than or equal to 200, or are you getting more than 200 sometimes?

We need more than 200 steps always :frowning:
Thanks in advance ;D ;D ;D

Please just answer the question.

We need more than 200 steps always :frowning:

Read the question in Reply #1 again and then answer the question that it contains.

achieved steps always less than 200.

Great. I suspected that was the case but it wasn't clear from your description. If you send pulses to the stepper motor too quickly, it can cause it to miss steps. This can lead to the abnormal vibration behavior you reported. You can experimentally determine the minimum pulse interval that will provide the highest possible speed without missing steps.

Yes, I agree with your point. I am a beginner in electronics, can u suggest me a circuit diagram with some simple sketch which can run the motor without vibration

Why not just reduce the speed of the motor in your existing program?

How can I reduce the speed of the motor in code ??? didn't have an idea

Please post your full sketch. If possible, you should always post code directly in the forum thread as text using code tags (</> button on the toolbar). This will make it easy for anyone to look at it, which will increase the likelihood of you getting help. If the sketch is longer than the forum will allow then it's OK to add it as an attachment. After clicking the "Reply" button, you will see an "Attachments and other settings" link.

Please always do an Auto Format (Tools > Auto Format in the Arduino IDE or Ctrl + B in the Arduino Web Editor) on your code before posting it. This will make it easier for you to spot bugs and make it easier for us to read.

When your code requires a library that's not included with the Arduino IDE please post a link (using the chain links icon on the toolbar to make it clickable) to where you downloaded that library from or if you installed it using Library Manger (Sketch > Include Library > Manage Libraries in the Arduino IDE or Libraries > Library Manager in the Arduino Web Editor) then say so and state the full name of the library.
