Great video! You save my mind! But, in my inverters P07.08 shoud be 3, and under the hood i have 4 point switcher. If you want to operate 0-5 V it shoud be off-off-off-off position. For 0-10V it shoud be on-off-off-on.
I used a simpler and cheaper solution. Used the 0-20 mA current input and a homemade vactrol to modulate a 12 V tension. The vactrol consisted of a LED pointed to a LDR encapsuled together with thermoshrink. Got a linear enough response from the setup, driving the LED via PWM, got a 0-22 mA current running through the LDR from the 12V source.
@@avyadav9180 may be he is driving led britness through arduino pwm output and he made voltage divider arrangment next to led ......so that u will get variable voltage directly proportional to led brightness..........I must say this is smart solution but we can stay depends on led and such set-up......
Nice and help full video. How do turn on/off(M3/M5) the rpm's as I see the module only controls the Hrz/rpm. On my own I would have to panel start, og use fwd output by a 12v std relay power from 0-24v port for the camshaft stock 775series motors, and then I use output of relay as my switch, but relay gets weaker as the power drops down
hello and congratulations for your work I have a vdf identical to yours, an YL620A and I am having a problem, maybe you can help me please. the spindle works well with 5000 rpm to 24000 rpm but as soon as I lower the rotation below 4000 rpm there is no more power and the spindle stops. My drive is new, maybe you have already encountered this problem? thank you
The YL620-A has red dip switches J2 & J3. It looks like if J2 #1 & #2 are OFF it's 5V and if ON it looks like 10V. Can you confirm this or are these switches for something else.
@Maker tutor The converter that you used accepts PWM signals between 1kHZ - 3kHZ Pin 11 of the arduino uno has default frequency of 490HZ. How are you still getting the desired output? Did you make any changes in the code to set the frequency to be between 1-3kHz?
Alri pal.. I have a 3 phase VFD. It's a 380V 1.5KW?? I haven't gotta clue what the story is. I see there are 1 phase VFD's also? Could u please tell me what is the difference. When I saw the video title I was a bit taken aback.. I didn't know u could use a VFD with ARDIUNO.. I'm a newb btw so I guess that is clear after that statement.. Are they both controllers? Variable Freq Drives are for what? Are they used to control the speed of my spindle or is their task something different?? Current mayeb? Like I said I'm a complete novice who is learning omn the fly. Any helpful adice u could give me would be greatly appreciated. Love ur channel btw. Why don't u speak a little on here? I think a voice is far more helpful on videos than just printed word. Sometimes the print on screen is very hard to see.. Anyways the content is always brilliant my friend.. Hope u have had a nice Xmas and best wishes for 2023..
Great video (not so much interrested in the voltage doubling side of it...) for the life of me I could not figure out where to connect the pwm signal on the vfd. Your video cleared that up
Is it possible to connect the pressure transducer and VFD for variable speed to the reference 4-20mA ? If is it possible then please help me to make it
Sorry to say but many or most of these so called converters have defects. The reason why many people are compaining.. the trim pots are defective and then some have 10k pots (103W) on and some 100k (104w). On mine measuring to one leg from middle gave constant of 5.2 k ohm and the other 0.03 even if i turn it in all directions, replace pot after testing ok and putting it on pcb it did the same.. not sure if its the pcb thats faulty or what..
I cannot get anything more than 1.2v out of my pwm to 0-10v converter. Using multiple cnc boards (default Comgrow board, ramps v1.4) it's driving me mad
Hey guys. Take good care of that company IcStation. They are liars. They promise that they resend your order if it's missing but they don't. It's better to buy from someone who is obliged to resend or refund your money back.
@@lachim28 For me its not ok. Also the input for the PWM ist connected to the same GNDs. I like to seperate the GNDs from the FU and the Arduiono (PWM). So had desampled the Optocopler and the terminal for cut the GND on top side. On bottom side, i make an GND Island around this two pins.
If you using these voltage converter and want to get fully 10v output from 5v uno pwm, that is very simple..just give the uno external power 9v and u will get the fully output 5v from uno🙂👍
thank you for sharing this video, it's very helpful, but I would like to ask something, in my case I'm using Arduino uno with a cnc shield, could you please tell me how the connection would be? thanks again for your response
No need of voltage doubler. Very simple solution I here. Connect a one side of 2-10K resistor to 10 volt of VFD and other side to collector of NPN transistor. Connect emitter of Transistor to ground of VFD. Connect the collector to Vin of VFD. Now connect the pwm pin of Arduino to base of Transistor with 2-10K resistor and ground of Arduino to ground of VFD . Your system should work alike a charm. Further to make the PWM analog, insert a capacitor between collector and emitter of transistor, or between Vin and ground of VFD. Capacitor should be of small value, otherwise the speed won't change as quickly as without capacitor
i bought this chip.. and the max output was only 5.28v am i missing something? the pwm voltage is already at maxed out.. and tried the potentiometer and doesnt really go higher than 5.28v..
Sorry to say but that is a waste of money. I just connect for the spindle control pin from arduino to vfd.. i didn't have to change the input gain to 200% either but i just change the vfd s8gbal to 5v, just simple, its all inside the manual
@@syamsulhussin8089if you put jumper 1 up to on and leave the rest to down (off) you set the video to accept 5v but testing I found you need 5.3V to get 400hz (24k rpm). Looking to see I there are adjustments to increase this
Mam can you please make a k type thermocouple based vfd speed control inverted (temperature increases and speed decreases) please mam i need this help Please

Hi !! Im just wondering why you didnt use analog upper value (3.11 as i remember) to half value, it will map voltage and you can use full rpm on 5v :D
thank you sooo much. I was having the same issue on my CNC 😀
Nice work like your projects/content keep up the GOOD WORK

What are the parameter settings from the VFD after factory reset, please? thx
Do you need this module for on off control or is 5V sufficient. I would think on/off would just be 0V or 5V?
Hi, I want to convert pwm signal to 10v voltage using IC station but when I try the IC station module I get maximum output around 8.6v only? why?
The YL620-A has red dip switches J2 & J3. It looks like if J2 #1 & #2 are OFF it's 5V and if ON it looks like 10V. Can you confirm this or are these switches for something else.
For anyone reading this, you can set the control input on the VFD to get a value from 0-5v instead of 0-10v
How?
Please explain
@@xjstevie it's a setting in the menu of your vfd, in the manual you can find which code in the menu encodes the 10 or 5v

Hi, for some reason I do not have a signal on the pwm pin. Do you know how?
If I connect uno to vfd direct is it possible as 5v output signal, without signal booster
Yes, jumper one to on, In other words up
Why is my booster module only give output 1,4V in the maximum pwm from arduino
can i use it for hdd motor ?
