Spindle Reverse using 7i76e Mesa card not working

Hi Everybody,

I have a PathPilot system running for a Non-Tormach lathe using a 7i76e Mesa card. All seems to be working but I cannot get the Spindle DIR - pin to be activated.

I have connected the TB4 Spindle connector as described in the standard Mesa documentation - for simplicity and test purposes I'm connected to a 10V power supply.
Pin 1: Spindle GND
Pin2: 0 - 10 V output from Mesa card
Pin 3: Spindle 10 V
Pin 4: not connected
Pin 5: Spindle Enable -
Pin 6: Connected to Spindle 10V
Pin 7: Spindle DIR - (the one I cannot get to work)
Pin 8: Connected to Spindle 10V

The 0-10V output and Spindle Enable work fine.

The HAL file contains the following Spindle information:

##-- spindle speed control

net spindle-enable <= motion.spindle-on
net spindle-enable => hm2_7i76e.0.7i76.0.0.spinena
net spindle-cw <= motion.spindle-forward
net spindle-ccw <= motion.spindle-reverse
net spindle-cw => hm2_7i76e.0.7i76.0.0.output-14
net spindle-ccw => hm2_7i76e.0.7i76.0.0.output-15

Any help would be greatly appreciated

Regards Danie

How is your vfd setuped to interpret those two signals. Probably you should consult that manual and change pins behaviour. Does it work when set by 'wires'?

If spindle is stoped, can you go reverse

Try
net spindle-cw => hm2_7i76e.0.7i76.0.0.spindir

Although you don't show how you have done it you may also want to use the "abs" version something like spindle-vel-rpm-abs for the spindle speed.

Thank you for the feedback.

To keeps things uncomplicated I'm currently testing without a VFD, the GND and 10V is connected to standard power supply and I monitor the Spindle OUT (0-10V signal), Spindle enable - and Spindle DIR - with a multimeter. Spindle OUT and Spindle Enable - works perfectly and I can start, stop and change the speed of a DC motor with 0-10V input but it does not matter what I do on the PathPilot interface I cannot get the Spindle DIR- to make a change from 0V to 10V or vice versa.

Sorry, but i'm not in the pathpilot varation. In stock lcnc the spindle gets instantiated now, means spindle.0.xxx, spindle.1.xxx, etc.

As Hakan said, try connecting "spindir" in your HAL. If you don't do that there won't be much happening on the Spindle DIR pin of the mesa card.

Yes, spindir on a 7I76/7I76E is a completely independent output, it
neither affects nor is affected by the other spindle signals

I have included the line in my .HAL file and now the DIR pin is 10V for CW and 0V for CCW. Thank you very much for your help
