Help needed to get my 7i76E + 7i85S + 7i73 on my mill going.

It would be almost identical with a 7i76. Except that the "encoder.N.." pins become "hm2_5i25.0.encoder.00..." and the VFD outputs become hm2_5i25.0.7i76.0.0.spindir / spinena / spinout.

Hello Andy,
I can not do it.
the following error appears:
>>> hal: 86: signal 'spindle-pwm' of type 'bit' can not add pin 'hm2_5i25.0.7i76.0.0.spinout' of type 'float' <<<

What is wrong?

This is my .hal
Code:

That hal file seems like it came from a parallel port configuration so not really suitable for a 5I25/7I76
I would start with a PNCCONF created configuration for the 5I25/7I76

peter: I think the rest is OK, but the spindle pwm is for a parallel port.

Peter: You actually have too _much_ in the HAL file. Delete all references to the pwmgen HAL component, and connect the abs function outputs directly to the 7i76 spindle pins.

You also don't need this section:
Code:
#----------nachgetragen # connect the HAL encoder inputs to the real encoder. net spindle-phase-a encoder.1.phase-A <= hm2_5i25.0.encoder.00.input-a net spindle-phase-b encoder.1.phase-B <= hm2_5i25.0.encoder.00.input-b net spindle-index encoder.1.phase-Z <= hm2_5i25.0.encoder.00.input-index
The only 7i76 encoder pins that you need in the HAL are the position and velocity output pins.

Have today 3D printed some parts for the gearbox discussed earlier.

Attachment not found


Will be glued to housing

Attachment not found


SMC D-Y7P

Attachment not found


Arm to be glued on selector.

Will try to get the inductive sensor for Hi/Lo gear fixed hopefully tomorrow.

Gday Rod, thanks.

I hope it will serve me well.

So now also Hi / Lo gear detector in place. Using Contrinex LHK-3031-303 with adjustable 'focus'.

Time to install the cables to a RJ45 connector

Cabling ready and tested so now it is time to tinker how to get this all working.

Attachment not found



With above I get 100 to 2500 rpm, spindle motor fixed to high speed = 2850 rpm and Hi / Lo + Gears A to E.

So what would be the best way to get this working? Yes there are combinations of settings allowing two ranges.
Any pointers on what to read?

Have a look at lut5 as that gives you 5 bits of input. Its pretty cryptic but I am sure Andy will help you. He's the expert on it.
I think once you resolve lut 5 to a speed, you should be able to use a mux2 to multiply the result by 1 or 2 depending on the hi/lo gear selection.
