At least that agrees with the Sauter table in your image above.

It looks like it's connected to a switch in the motor, so my guess is thermal overload protection, and that symbol is an signal isolator connected to a fault circuit.

If you do a bench test, that will verify the Acorn is outputting the full 0-10v range, and narrow down the problem between the Acorn, or more likely, the VFD.

What voltage values did you get during the spindle bench test?

Unfortunately, you can't buy MAPP gas anymore in NA. The crap being sold as MAP-Pro barely burns hotter than Propane: 3730 vs 3600°F but costs twice as much.

Most likely it is a broken cable, or a blown probe fuse. The cable is detailed in the DP-4 manual so you can a multimeter to check continuity on the wires. The fuse is F13 on the AllIn1DC board.

RealVNC is free for up to 3 computers. Great idea Uwe.

Depending on the pulse characteristics (it would need to be a differential 5V signal or converted into one), you could wire this into the spindle encoder Z (index) channel. You could then use a T flip flop to remove every other pulse, or possibly program a 2.0 gear ratio.

Since there is no parallel port involved, it's going to be a little tough to set it to enhanced mode.

Shawn - send them to me. I'm happy to help you clear out some of your junk.
