Hello!
Thanks for all of the help so far- this forum is really supportive!
Again, I need help on connecting my bob to the vfd. I cannot find the instructions how to connect this.
Here is my BoB and VFD connections.
All help greatly appreciated!

Please have a look - is this connection correct? Thanks!
You want the 0-10v/GND connections. Not the pwm/m5v ones. GND-acom. 0-10v-vi.
Before connecting vfd:
1. Make sure vfd is set up to accept 10v analog (not 5v).
2. Test the analog connections from the bob give the correct output voltages using a meter.
Get hold of Mactec54 on the forum to give you advice on all your peramiters.
Also read some of the other posts in the spindles/vfd forum section.
There's a couple of recent threads using similar vfd that might serve you well.
I though I replied but the post must be somewhere else
Yes, 0-10v Analog output to VI / ACM is correct for speed control
The Rely connection is FOR / DCM so as per your drawing is correct
Before you connect the 0-10v to the VFD Drive you must have it working at the Breakout Board first to check this use MDI
MDI M3S12000 this should give you around 5v there appears to be a pot on the Breakout Board this will allow you to adjust this voltage
So try different speeds in the MDI to make sure the voltage matches the speed
What spindle are you using as all the Parameters have to be set correct for this to work
Mactec54
Inverter specs - HY04D023B
single&3 phase 220v 50hz
4.0kw
10A output current
suitable motor - 4.0 kw
the inverter came together with the spindle.
I am located in Europe w/household current 220V.
If spindle is only an 18000rpm max unit, you only want to be getting 9000rpm at 5v.
Check your pulley settings and any other settings ralated to max speed in your control.
Remember not to overlook minimum % settings too so spindle can't be overheated by running below minimum rpm spec.
Get your control right first while waiting for Mactec to reply regarding vfd.
OK what does it have at 18,000 RPM and 9,000 RPM, it seems that you need to make some adjustments with the PWM or the Pulley Ratio
What do you have the PWM set too??
Are you using 3Ph power supply or Single Phase??
Does your spindle have an electric fan or fix.??
Your 4Kw spindle can't be 10A it would be a minimum of around 14A up to 16A with a power factor of 0.75 it's normally much better than this for VFD driven motors
Mactec54
Ok, I set the max spindle speed to 18000 in the Spindle/Pulleys window.
Now I get:
m3s9000= 5.3V
m3s18000= 9.43V
I tried tuning the volts w/ the potentiometer to get closer to 5 or 10V, but there was no change when turning the pot.
I am using single phase power supply. Spindle only has the fan on the rotor shaft - no electric fan. Regarding the 10A- that is what is stamped on the plate.
Where do I set PWM values?
Could you please send me the VFD parameters.
Yes, good find on a second look they don't appear to in the correct, 0-10v output, they should be on the (2) screw Terminals closest to the Relays he may have it correct as he has 9.43v so that is close to 10v the other output is 5v, he should check though to make sure.
Mactec54
Make sure you are wired to the 0-10v analog output, I missed it on your drawing which is incorrect that is most likely why the trim pot was not doing anything because you have it wired incorrect.
I hope you have enough juice as that is a bigger than normal spindle for a Single Phase power supply, you will need a 30A supply for it to run on Single Phase and that will be border line.
The spindle amp rating of 10A is incorrect for a 4Kw motor 2.2Kw run at up to 10A
This should get you going

Thanks for the settings.
I moved the VFD jumper from the VR position left to the VI position
I set PD001 to 1
I set PD002 to 1
all else was set as per your settings list
I am unfortunately unable to adjust the speed from Mach3. 0-10V output is working correctly (5v at 9000rpm, 10V at 18000rpm).
The attached photos show my ports and pins settings. The photo of the speed setting shows the setting at 500, but the spindle is turning full speed, at the same time the inverter shows full 300hz.
Also, the RPM in the spindle speed window, only shows 0, it does not show any rpm's.
What am I doing wrong?
Also I am getting "Too fast for pulley. Using max." error
Check the jumper J1 it may need to be in its other position this happens sometimes
Check these Parameters

When connected to the VFD is the 0-10v still changing with the different speed commands.
The wires between the Breakout Board and the drive need to be shielded or Twisted Pairs a tight Twist

Will replace wires- currently neither shielded or twisted.
I tried with the jumper in the original position, same issues.
When connected to the VFD, and I run M3S9000, the volts jump from 5 to 10v, once I engage the spindle.
...and the spindle automatically starts spinning once the computer is turned on and sends power to the bob.
replaced wires with tightly twisted pair. Same behavior.
