I'm not sure what you mean by this:

I don't know how to run it axis office

How you change the rotation direction would depend on how you wire the vfd:

How are you driving the FWD and REV inputs? What interface card? What are your HAL connections?

So far you have:

net spindle-output      => hm2_5i25.0.7i76.0.0.spinout
net spindle-enable      => hm2_5i25.0.7i76.0.0.spinena
net spindle-ccw         => hm2_5i25.0.7i76.0.0.spindir

With your setup you could wire the "hm2_5i25.0.7i76.0.0.spinena"-contact to FW-input on the vfd and
the "hm2_5i25.0.7i76.0.0.spindir"-contact to RV-input on the vfd.

Then you could do a bit of logic in the hal file:

net spindle-output => hm2_5i25.0.7i76.0.0.spinout
net spindle-enable => hm2_5i25.0.7i76.0.0.spinena
net spindle-ccw => hm2_5i25.0.7i76.0.0.spindir
net spindle-enable => and.vfd-fw.in0 =>and.vfd-rv.in0
net spindle-cw => and.vfd-fw.in1
net spindle-ccw => and.vfd-rv.in1

net vfd-fw <= and.vfd-fw.out => hm2_5i25.0.7i76.0.0.spinena
net vfd-rv <= and.vfd-rv.out => hm2_5i25.0.7i76.0.0.spindir

Last edit: 20 Oct 2020 15:04 by Aciera. Reason: hal code suggestion does not work as spinena is connected to spinout in the 7i76

So you did, sorry.

net spindle-output      => hm2_5i25.0.7i76.0.0.spinout
net spindle-enable      => hm2_5i25.0.7i76.0.0.spinena
net spindle-ccw         => hm2_5i25.0.7i76.0.0.spindir
...
net spindle-enable             <=  motion.spindle-on
net spindle-cw                 <=  motion.spindle-forward
net spindle-ccw                <=  motion.spindle-reverse
net spindle-brake              <=  motion.spindle-brake

I think that the issue is that the outputs of the mesa spindle interface are spindle-on and spindle-reverse. So when the spindle is running backwards both the FWD and REV inputs to the VFD are active, and it interprets that as a FWD.

You might need to move the VFD FWD terminal off of the 7i76 spindle connector and use a GPIO pin instead. (I don't think that the spindle connector on the Mesa card is configurable)
An alternative is to use a small relay to disconnect the "FWD" signal when the "REV" signal is high.

Ah, I think Andy could be right. The spinena might be connected to the spinout on the 7i76. So you would use the spindir output to channel the spinena signal to either FW or RV-input of your vfd.

I just checked in the manual:

The SPINENA output is special as it uses the same signal that enables the analog output. When the analog output is enabled, theSPINENA OPTO output is on.

So Andy has it right.
