A2-8002 VFD set up - any help appreciated
« on: September 19, 2021, 05:04:19 AM »
Hi there, recently posted on the Mach 3 vista/win 7 section, but got no response to this :-

Hi all,
Have finally got axis movement  :D
I am now on to setting up my VFD - model number A2-8022 (https://www.ebay.com/itm/313387171700), manual attached - FYI
Was planning on controlling it with a usb to RS485 adapter (https://www.amazon.co.uk/dp/B0721BB8PQ?psc=1&ref=ppx_pop_dt_b_asin_title) as i would like Mach 3 to control it.

I see that the Huanyang VFD has a plug in written for it, will that work on my VFD?

Any issues anyone can foresee?
and with that any guidance?

Thanks in advance.

Does anybody have any information i can use. Or am i facing ditching my current VFD to replace it with a Huanyang.

Looking into it a bit further, and trying the plug in i can confirm it doesnt work - unless i have missed something - i get a dialogue box saying 'unable to read value' when configuring the plug in.

Do i take it that because i havent had any replies nobody has had any experience with this issue.

Are there any generic plug ins that will work?

Most VFD's have a parameter to select the control input, this could be 0-10V, PWM, 0-5V etc usually in the first 15 parameters.

If it has PWM you should be able to set up Mach's PWM output and drive it direct.

This may help :-
