7i76E Spindle configuration

The OP was supplied with a config as requested for 4axis and a spindle, to 24k I think, by PCW. Even with is he could not get an output, taking this into account PncCONF is not the issue.
If the OP could be so kind as to supply a picture of the wiring of the actual spindle connector and a diagram as well of how he wired it I think that would be quite helpful. This is the second time I have made this request.
To OP seems to have missed or ignored the bit about PWM not being involved in configuring the spindle.
Just making a guess I suspect that spindle + and spindle - are not being supplied with an isolated voltage. If this is the case spindle out with not have a voltage that is in line with the selected spindle speed.
Wiring of the opto isolated outputs can be tackled later.
To reiterate the OP has a config supplied by PCW, which we can take as being gospel and if the board is wired correctly will work.
For testing I would not have the spindle connected, I would just be monitoring the spindle output with a multimeter referenced to spindle - .
This is actually how I went setting up my spindle, but using a smart serial board as I required the servo driver to be some distance from my 7i76 and did not want a small analogue voltage being transmitted over a long cable. Paranoia may have had been high that day.

There is no tension on pins (1-2) (1-3) of the TB4
That means no Spindle output is possible.
The 7I76/7I76E/7I76EU do not supply the 10V.
The spindle output on these cards works as a
potentiometer. Typically the 10V is supplied by
the VFD.

Thank you all for the responses. The VFD GA500 is already installed in the machine and I don’t have it here. I have an LS600 on my work desk which I am using for the tests. I will try to send you the information you are requesting as soon as possible.
PCW !. Thank you for coming back! From the heart!
I advance the board that I am using in the TB4 connector, I believe, as PCW explains, that I am not supplying the 10vcc. I am going to check the LS600.

I'm a bit concerned about the STEP/DIR wiring.
It appears that the thick white wires are grounding the STEP- and DIR- pins
This should never be done as it shorts out the STEP- and DIR- pins
possible damaging the driver chip.
If STEP- / DIR- are unused, they should be left unconnected.

I am going to check the connection, I should have connected TB2 pin 2-4 with the white wires [ Pulse - ] [ Dir - ] from the Driver.
the pink cable from the X connector seems to enter pin 2, I need to check!!
thank you very much for the observation !!!!!!!!!!
