Introduction To Stepper Motor Motion Control. Pulse And Direction.

- In this lesson we go over how stepper motors and drives use pulse and direction for precise positioning in motion control applications. Steppers can use the pulse and direction control to maintain accuracy despite not requiring an encoder. Using basic switches wired to the pulse and direction input, we can make a tutorial where we manually move the stepper motor.

Great video thanks!
Glad you liked it!
Thanks for these videos, seriously!
Glad you like them!
Thank you Tim !!!
You are welcome!
One little thing to mention: The direction pin. This pin "cares" about the logic voltage on it. (The other pin just waits for a pulse, to move one step) As such, one must know which logic value corresponds with which direction - CW, or CCW.
Great job
Thank you.
Thank you for showing us this video, I’m still struggling to connect DC motor to micro820 with no motor drive trainer any key points should I follow?
small overlooked nuance: Microstepping. Using clever tricks, the driver can offer you many more "stops", than you'd normally get from just the coils in the NEMA motor. It makes no difference to the pulsing. One pulse equals one Microstep. The number of microsteps (aka subdivisions) is configurable on the motor driver itself
When you are wiring something up, you should show a ladder logic diagram or some sort of schematic. This helps things make more sense when there are so many wires and components
This trainer came with great documentation. Did you go through it? If you are still having trouble, contact him. He is very helpful
Check out the other videos I mention, there are schematics in them.
Fun fact: when probed, the Pulse signal often looks like a 50% duty cycle. This is incidental, it's because every edge (up or down) counts, and the speed tends to remain consistent, hence giving the appearance of a 50%
Oops. Upon further investigation, That's not correct. Nothing happens on the falling edge. (Source: DRV8825 Datasheet)
Please post a video on how to program bit shift right
thanks
Here you go Silvio

Fantastic! Can you explain us hou these drivers work internally? (H bridge, current decay, chopping technic,etc) please .-. ._. ;D
No, that's too far off topic for our channel 😁
Hi Tim could you help me? I am having the next error on the move absolute module MC_FB_ERR_
PROFILE
The function block cannot execute because the motion profile defined in the function block cannot be achieved.
Correct the profile in the function block.
Could you explain me why is this keep happening and how to resolve it. Thank a lot
Sir, which motor and drive are used in this case ............?????
Afterall it's great video .... thank you sir 🙏🙏👍
Not sure, this one isn't a trainer we build.
