Stepper driver controller

Selecting a chopper driver and configuring it for a specific motor requires a good understanding of both the motor and the controller.

The next step is to define the TB to Arduino connections and the motor interface type. The motorinterface type must be set to 1 when using a step and direction driver.

You can find the other interface types here. Next, you need to create a new instance of the AccelStepper class with the appropriate motor interface type and connections. The name that you give to the stepper motor will be used later to set the speed, position, and acceleration for that particular motor.

You can create multiple instances of the AccelStepper class with different names and pins. This allows you to easily control 2 or more stepper motors at the same time. For this we use the function setMaxSpeed and setAcceleration.

In the loop section of the code, we let the motor rotate a predefined number of steps. The function stepper. If you would like to see more examples for the AccelStepper libary, check out my tutorial for the A stepper motor driver:. In this article, I have shown you how to control a stepper motor with the TB stepper motor driver and Arduino.

I hope you found it useful and informative. If you did, please share it with a friend who also likes electronics and making things! I would love to know what projects you plan on building or have already built with this driver. If you have any questions, suggestions, or if you think that things are missing in this tutorial, please leave a comment down below. He seguido tu tutorial y todo funciona como es de esperar. I need guidance regarding the following points: 1. How can I calculate the exact rpm of motor?

How do I know what exactly happens in the AccelStepper libraries? How shall I set the max speed and Acceleration values in the program to get the speed in the above range? When I check with a multimeter the pulse and direction pins are showing voltage as expected and the VCC is showing the 12v supplied, but nothing is going to the coils.

What could be going wrong? Very nice explaination! I have a simple question.. I want these to be synchronized exactly as possible for smooth operation. Is there a limit to how many times number of drivers I can do this? Thanks for your help! Hi, Thank you for this tutorial which is very useful. I want to use the DM driver for my stepper motors and I want to add an absolute encoder to the motor.

It is possible to command the stepper motor in function of values that I will receive from the encoder using this code? Thank you. I am using the stepper motor to control the angle of a solar panel so that it always points towards the sun. I needed this tutorial to tell me the basic operation of the TB stepper motor driver.

You did a great job doing that. I suggest a correction as follows. Well done. I came across the tutorial while searching for knowledge about what determines when the TB driver and others like it should be connected in: a Common Cathode config and b Common Anode config. While I did not find the answer to my question, I learned a number of other things that improve my understanding about drivers. I notice if the unit sits powered, the motors get a bit warm.

Not hot. I have a 2. I have not added a power switch yet. Maybe I will just do that. To enable it again, simply set the pin low with digitalWrite pin,LOW ;. Thank you for the tutorial, it was very helpful however I do have a problem. I have no access to a 36V power supplier and the strongest one I have is 19V which I suspect is not really a problem for the motor that I use which is the sl42stha.

You could try to increase the current settings with the dip switches which might solve the problem that you are having. Thank you for this straight forward tutorial. Made things easy for me. Other tutorials complicate things with potentiometers and switches that I can worry about later.

This way is better. Your explanations were very helpful for my project. I wired the stepper motor like you displayed in your drawing. Controllers have multiple inputs and outputs to communicate with more than just a motor. Connect sensors and switches or link multiple controllers together to coordinate movements between motors. They're also compatible with encoders not included , which monitor the position of the motor's shaft and report back to the controller.

Simplify setup with these single units. The controller and driver are combined, so you can determine all your settings from one device including number of steps, direction, and step resolution. They have multiple inputs and outputs to communicate with more than just a motor.

They connect to an encoder not included , which monitors the position of the motor's shaft and reports back to the controller. Step resolution determines the size of the step a motor takes. The smaller the steps your motor takes the more smoothly and precisely it will move.

With a built-in controller and driver, these stepper motors come ready to program and operate. After connecting to a computer for initial setup, the controller can store and run programs on its own. When the shaft stops, it holds its position even when a counteracting force is applied to the load.

All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors. When relative positioning is critical, such as coordinating motion in a multi-axis system, choose a motor with an encoder. The encoder monitors the position of the shaft and reports back to the controller. Holding torque is the force needed to move the shaft out of position when it is stationary.

When the shaft is in motion, torque generally decreases as speed increases. Use a torque-speed curve to confirm which motor will work for your application. Increasing the number of steps directs an even more precise position and reduces the step-step-step motion to mimic a smooth, continuous rotation.
