Emcoturn 120 lathe retrofit

PWM and PDM are both the same thing, and in this case correspond to the spindle VFD output. Just leave them as they are.

Like Andy said the PDM is part of the settings for the analog output intended for controling the spindle VFD.
And the encoder is also intended for the spindle encoder.
Like Andy said, just leave those settings alone.
Ditto on the watchdog, pwm generators, and smart serial ports (leave them alone as well).

ok now it gets into the real substance. page 4 io1

Im not sure how these numbers corrospond to the physical pins on the pcba. that would help me with assignments

is I/O1 the first connector in the TB2 row or is this the parallel port pins?

The 7i76 GPIO pins are listed on the 7i76 tab. (the last one).
The other tabs are (effectively) the parallel port pins. These are the step generators and smart-serial extension.

ok thanx, thats why it seemed like there were too many off to the beach

screen 4 7i76e tb4

analog output

seems like it doesn't have enough pins, the plug has 8 pins. how do these match up, do I need to add the other pins in somehow or is it a manual edit in the file later? tb4 connector has the vfd control

also all of the stepper motors connections are on tb2 and tb3 but there is no tb2 or 3 tab. spindle encoder is on tb3 as well.
