Hey! Consider the connection diagram of a stepper motor and a PWM generator. The easy way to connect! How to assemble and connect the circuit for Nema 23 and tb 6560 stepper driver. Enjoy watching! Thanks for the comments!
The scheme is quite interesting! A wide range of settings for the TB 6560 stepper driver itself allows you to very accurately adjust the speed.
Good ideas in showing with wiring diagram ,
Thanks for watching and commenting! I'll keep this in mind for the future.
Thanks for the video. At 3:07 can you explain why do we need resistor between PWM and GND?
For smoothing and separation of working impulses. The PWM module proposed by me produces signals, only on one wire. This is not enough for the normal operation of the stepper driver. If you connect a circuit without a resistor, the device will not understand the direction of rotation. The resistor is needed, only for this circuit and these components. If you have other components, then it will probably work without it. Thanks for watching and your question!
I want to control a single LED of 1.8V. Is it possible to lower the output voltage? Maybe with a buck converter behind the PWM?
This circuit works well with a stepper motor, I don’t know how it will behave with LED. There are also difficulties with a significant decrease in power in this circuit. This PWM starts working normally from 5 V. If you place a step-down circuit at the output, most likely it will try to equalize the power and there will be no normal glow. I advise you to try a regular PWM, with a minimum power supply of up to 5 V and connect the LED through a resistor.
@@DIY-parts Many thanks.
I don´t want to use tb6560 for a motor, but solely to enhance the amperage of the pwm-generator... The generator outputs just 5mA, and I need 1000mA to trigger fast an IGBT. Do u think I can use tb6560 as an IGBT-gate-driver at 35-45kHz ???? cause u went up to only 1kHz, and I cannot find any data, about how fast the tb6560 can switch (or understand the tb6560-datasheet)... would it still work, if u set your pwm-generator to 35-45kHz? Thanks...
Thanks for watching and asking. To begin with, the TB6560 does not work very well at high frequencies. As a device, it is more designed for traction forces with minimal RPM. As soon as the permissible signal level is exceeded, the driver crashes the pulses and a constant pulse line is obtained at the output. Which means that the signal to open will be IGBT will be constant. The stepper motor in this case seems to jam and it stops rotating. In addition, both the PWM module and the TB6560 are limited by 30V power supply. I do not know what control voltage your IGBT. Also, with this voltage, these modules will get very warm, TB6560 certainly. He still has a recommended 24-25 volts. I think it is worth considering for use, more powerful frequency converters for controlling the spindle for CNC. They also have an operating voltage of up to 400 V and a frequency range of more. I may be wrong, but on such small modules, it will not work. I hope it helped...
@@DIY-parts Thanks a lot for the answer, it explains a lot that I wouldn´t be able to find out else (aside to studying thick electronics books, that is ;-) Yeah it seems, that the 20V/0,5A are manageable by it, but not the 35-45kHz-high-frequencies, still, it was worthwhile asking, since I learnt something... By now, I ´ve found out, that there´s similarly cheap pwm-generators, that output up to 8A, but differ from their 5-30mA-cousins in a way, that I do not understand. But I´ll find out... I´m talking about the 8A ZK-PP2 pwm-generator compared to the 30mA ZK-PP1 pwm-generator. The power-difference is huge, but they don´t seem to do the same job, or maybe my lack of knowledge cheats on me here (description goes: "Note that the high-power PP2-type PWM driver is a MOS switch type output. When the load is not connected, there is no waveform, and the waveform is only after the load is connected" and that confuses me). Anyway, thank you a lot, I´ll find it out, I´ve come so far already...
Any PWM generator should produce at least some fluctuations and a P-shaped signal. Regardless of whether the load (consumer) is connected to it or not. The easiest way to check it (in addition to measuring instruments) is to connect a 12 volt light bulb to its outputs. When applying voltage to the ZKP 2 pwm generator at the same 12 volts and frequency changes, you can observe the pulsed glow of a lamp or LEDs, with a change in the frequency of flashes and their brightness. These units have no feedback from the consumer and it does not analyze whether the load has received a signal or not. Moreover, if the unit has 2 outputs, it can generate a split signal for each output. I have a video on my channel where, using such a simple block with 2 outputs, I assembled a circuit using the frequency difference and the result was a strobe effect. At which it is possible to stop the fan rotation (visually). And all you need is an LED strip and a motor with a controller from a quadcopter. I did it on the questions of my subscribers and in Russian. If you are interested, you can watch: th-cam.com/video/peRd02q_zNgT/w-d-xo.htmlhank you again for your activity!
@@DIY-parts Thanks... I thought that such blocks with 2 outputs can have a different duty-cycle for each output, but the frequency is then always common, and one-and-the-same, for both outputs (choosing a frequency for the 1st output fixes the frequency for the 2nd too)... Maybe I got it wrong... I´ll watch your Video!
@@DIY-parts I just watched your other video, it was very nice, I hope I can do the same some day, although I do not understand the explanation in russian...
the resistor should be 470 ohm? or in range, e.g 300-1k ohm is Ok?
It worked for me, stably, only at 470 ohms. But worth a try, with other values. It is possible that this can work with other parameters as well. Thanks for watching and your question!
porque la resistencia de 470 ohm?
Yes, 470.
Nice pics and music but nothing about what you are doing and why, not educational at all. 😢
Thanks for watching and your comment! I'm just starting the channel, there is something to work on :) If something is not clear, but there are questions, they usually clarify. Thanks again!
Ever thought about explaining what you are doing
Thanks for watching and your question! This video shows one of the ways to connect a stepper motor and the ability to adjust the speed without arduino and writing a sketch.
