Very informative video! Is there a way to have Accel/Decel control just like in the video with a p1000 PLC and a P1-04PWM Card while maintaining the desired amount of pulses? Regards, Basel
I suppose wit enough effort anything is possible ... BUT ... stay tuned. Rumor has it that the Productivity family of PLCs is about to get an upgrade this summer that will probably do exactly what you want with very little effort on your part!
@@automationdirect That's great! Can't wait for it. May I have a hint if it's going to be involving a productivity suite update or a new special high speed output card? I'm on the edge of getting a bunch of 04PWM cards for my steppers. *Shy face* Keep up the good work! Basel
Thanks for this really helpful video. At 2:42 you said the Productivity2000 controller gives out 500,000-1,000,000 pulses/sec. I can't find this information in their hardware specification anywhere. How can I find out the number of pulses my controller gives out???
Hi Raymond, You can find that spec on page 3 of this document cdn.automationdirect.com/static/specs/p2hso.pdf in the table "Pulse Output Specifications" under: Maximum Switching Frequency"
Hi, great explanation, but at 4:47 where do the 0.25 and 1.25 seconds come from ? and if we have a 5 seconds duration instead of 1.5sec , how do we know how much triangles we have in the area ?
Hi DoubleRhonRhon, That was an arbitrarily chosen acceleration time. You would put whatever acceleration time you have for your system, of course ... It was convenient that that time evenly divided into the total time ... made the math a little easier ...
@@automationdirect Thanks for answer. I'm novice with stepper motors. I suppose the acceleration time will depend on the motor model, and on the torque required for the movement, and the average rpm required. a lot of things ?

Great video with one thing missing. You seem to arbitrarily move the rpm of the motor up to account for acceleration and deceleration. Can you explain how to move the line and to where. I am a little confused as to how you picked that new hight.
@TheKlickitat - Thanks for the comment! Are you referring to the 720 rpm at time 6:41 in the video? That number isn't arbitrary ... it is calculated starting at about 3:58 in the video. Is that what you were looking for?
Hi there, thanks so much for sharing this helpful video, I'm little confused at the step dividing the isosceles trapezoid into 10 pieces, why is that not 12 or 14 cuz the speed would be different if we separate it into another number of pieces? Please help me out, thank you so much.
The first triangle is created by the duration of the acceleration time. Then you see how many of those fit into the rectangle and then add one for the decel time. So the number of triangles depends on the duration of the rectangle. The longer the motor runs, the more triangles you will need. In this example it turned out to be 10. This assumes that acel and decel are the same, of course. There are a lot more videos like this at www.automationdirect.com/videos. Just type what you are looking for in the search bar.

Click on "Stepper Systems" graphic in center of page or on "Stepper Motor" in left column, first bo (scroll down inside box) 4. Select the motor you want (the filers on the left help a lot!) 5. Click on "Specifications" The curves are in there.
Hi Donald, That depends on your application. In general, a servo will be higher performance and higher featured than a stepper. That usually comes with a higher price (and complexity - encoder feedback, etc). A stepper will usually be more cost effective. And it holds position without any “dithering” like a servo may have.
Yes, they are different. The controller sends the commands (usually pulses) to the drive. The drive then converts those to the high current signals needed to drive the stepper motors.

Hi Madesh, The 30,000 pulses is derived from the physical constraints shown in the equation at 2:09 in the video. We needed to move 3 inches using the given threaded rod, the math then tells us we need the 30,000 pulses to move the 3 inches. If you need more help, please contact our free tech support. The will be happy to help you. You can reach tech support here: www.automationdirect.com.
Appendix C example 2 = (45 mm ÷ (10 mm/revscrew ÷ 1 revmotor/revscrew)) x 1000 steps/revmotor = 4500 pulses.... why did you multiply the distance to be traveled by the rest?
@Andreas G, thanks for the comment. Very good question! These are the same equation, what is used in the video is the simplified version, which I believe is more straight forward when you are involving fractions. Notice in the equation in Appendix C, Dload/i = 10 mm/REVscrew. To divide a fraction you take the inverse and then multiply. For this example, the inverse would be 1/10 Revscrew/mm. This is what was done, in the video, the 1 rev/0.2 inch is the inverse of the Dload/i, and then that term was multiplied.
@@automationdirect Hey, in the video, screw pitch is mentioned as 0.2 inches. but the same time you said "each rotation moves the screw 0.2 inches." So, isn't that dload? since P=1/dload, isn't screw pitch is 5 rev/inch ?

Could anyone tell me where can I get those graphs to compare the speed?
Those curves are in the specification sheets for each motor.

2. click on "Motion Control" in left column
3. Click on "Stepper Systems" graphic in center of page
or on "Stepper Motor" in left column, first bo (scroll down inside box)

what is the best drive a stepper or servo mortor?
Hi Donald, That depends on your application.
In general, a servo will be higher performance and higher featured than a stepper. That usually comes with a higher price (and complexity - encoder feedback, etc).
A stepper will usually be more cost effective. And it holds position without any “dithering” like a servo may have.
Pleasa I need your hlep I have cnc X part =70kg. And part of Y=150kg. How match toirque of motor do I need thanks
Part II of this video shows you how to calculate the torque required. See if that answers your question ...
@@automationdirect thinks alot
Are drives and controller different? If so, could someone explain it briefly?
Yes, they are different.
The controller sends the commands (usually pulses) to the drive. The drive then converts those to the high current signals needed to drive the stepper motors.

from where you get the 600 rpm ?3:39
@Anwar Alfaqeeh Alhusseini, thanks for the comment. The 600 rpm is obtained through the equation explained from 3:20 - 3:39.
thank you for replaying to me >>>indeed you tube is what i need >>>put i dont understanding >>>because an weak in English
thank you again
10 rev/s = 10*60 rev/m =600 rev/m
Another way:
At 2:17 you have 20.000 pulses/Sec thats frequency [Hz] f=20000 Hz
At 2:05 you have steps per rev or pulses per rev : S=2000
So according to Takashi Kenjo formulas: N=60f/S =(60*20000)/2000 = 600 RPM (rev/minute)
Hadis Adili thanks 🙏
I understand it
10rev/sec*60sec=600rev/m=600rpm
