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

I can hear that motor relay is activated so it seems VFD is not getting any voltage from 7i76e output.

From the figure in the previous post, speed_out is zero, so it should not run. See above.

if (inputs_sum > 0 && geartouse == gearengaged) { // Everything ok
gearshift = 0;
wantedgear = gearengaged;
speedratio = ratios[gearengaged-1];
enable_out = enable_in;
} else { // Should change gear
gearshift = 1;
wantedgear = geartouse;
speedratio = ratios[geartouse-1];
enable_out = 0;
speed_out = speed/speedratio;
speed_out = 0.0;
}
}

I moved the speed_out speed calculation to the right place. Now it should work. Remove the arrow.

OK, will go down to the workshop and try y´this out now.

I think I still prefer my switch{} as a way to determine the gear, it can detect invalid combinations.

It might be better to multiply by speedratio, just so that there is no chance of a divide-by-zero if a config mistake makes speedratio=0

You have a good point. The way it is done now is not very error-proof.
One way to ensure only one input is active is to
if (input_a + input_b + input_c + input_d + input_e != 1) .......

I also have a feeling there are other erroneous combinations possible,
especially in combinations with the Glade input that is coming.

I don't mind if like you to bring back the switch-case.
