I had always assumed that machine MPG's generated one state change per click, but following Gene's discussion, I pulled out my 1988 Fanuc MPG, and saw that it was also 4-states per click. Obviously, one 'pulse'/detent
Does anyone know the rationale behind this? I assumed one always wants one step per click, so why not use a 25ppr encoder and use every change? Used as currently is, it would have to be a software /4 to be useful. You could also do a /2 or /1, but no-one ever wants a x2 or x4 on their MPG It's always x10, x100 or whatever, so the count/detent would always have to be n/4 x 1 .. or.. n/4 x10 in software. Alternatively, if I was going to make my own MPG, surely I would just make a 25ppr encoder and make it 1 detent/change? It's far easier for me to make, so surely it would have been for Fanuc too? What am I missing?
