Help with A2 Series VFD control with 7i96

Hey guys, 

I´m back with yet another problem I been facing.
First of all I ordered a Huanyang VFD but I seem to have gotten a clone. So, thats what I´m stuck with now.

I read here that it shoud be possible to control that VFD with my 7I96 instead of my now useless USB to RS485 adapter.

I also read that the 7i96 can give out PWM signals wich I could convert to 0 to 10V signals with a converter.
I need to get one of those converters. 

What I dont understand is, where on the 7i96 do i get the PWM signals? 
Do I need to assign them in the Pncconf wizard? 

What exactly do I need to assign an how do I wire this stuff? 
I added the connection sheet of my VFD down in the attachments.

Would be awesome if someone could help me with this.

Greetings,  Mike
 

IT can be done with 0-10v. 

Check out this thread.   7i96 spindle interface

As I understand from this, I take one of the unused Stepgens for the pwm control for the spindle?

What firmware do I need to run on the 7i96 then?

I run a 7i85s aswell. I read somewhere that it has the abillity to output pwm signals aswell?

I don't think there is standard firmware for this (7I96+7I85S+PWM).
but I can make a bitfile. Where do you prefer the PWM output to
be connected?

Does my current wiring setup change when I flash a new bitfile to my mesa combo?

My connections are currently as follows:

7i96:
TB1 Ste0, Step1, Step2 are for the X Y and Z axis

7i85S:
TB3 Enc0, Enc1, Enc2 are for the encoders fromthe X Y and Z axis.

Wiring wise, it would be nice to have the PWM signal on the 7i85s
TB1 Diff. Out 4 , 5

But any other place would do aswell as long as I know where it is ^^

That would be awesome if you could make a bitfile for me.

Thank you very much in advance.

This adds 1 PWM gen instead of the last stepgen on the 7I85S
I had to drop one more stepgen on the 7I85S for space reasons

 

Thia should not change any existing connections
 

Thank you very much.
I just ordered a pwm to analog converter, should be here in a day or two, then I'll give it a try.

Is there a way to donate you some money for a case of beer?

So I got my analog to pwm board yesterday, I flashed your firmware on my card, Everything is still working like before.

I wrote some stuff in my hal and ini files.
I set num_pwmgens=1
But where in my 7i84s do I connect the wires that go to my pwm to analog board?

You said that you put the pwm generator on the last stepgen.
I assume that this is would be on the connector TB1 Diff 6,7 ?
Connector Pin 9 to 16, do I need to use the QA QB or ID pins?

In my hal I had setup the spindle as follows:

loadrt hm2_eth board_ip="10.10.10.10" config=" num_encoders=4 num_pwmgens=1 num_stepgens=4 sserial_port_0=0xxxxx"

loadrt pid names=pid.x,pid.y,pid.z,pid.s

Did I forget something?
I checked every port on my 7i85 with a multimeter and I can not find where Axis turns on or of the spindle / pwm signal.

Would be great if you could help me here again.

Thank you and have a nice sunday.
