Spindle indexer help please

[Len-Tikular]

Thanks Adrian,

I have amended my sketch and I think it is now correct,
Blu = In1
Red = In2
Green = Gnd
Yellow = Vcc What would you recommend the supply voltage ?? Specification attached.
How do I configure MAch3 turn to read both these signals ?


However
Just in case we cant get this working I have fitted a single inductive pickup which gives a spindle out as follows.

M3 S1000 = Indicated True Speed = 60
M3 S5000 = Indicated True Speed = 360
M3 S10,000 = Indicated True Speed = 740
M3 S15,000 = Indicated True Speed = 1120
M3 S20,000 = Indicated True Speed = 1500
M3 S25,000 = Indicated True Speed = 1888

It looks fairly linear. But how do I get the requested M3 speed to be equal to the Indicated true speed ?
The output from my BOB is a 0-5Vdc
I have set pulley No1 to min speed to 0 and Max speed to 25,000
Spindle feedback and Spindle averaging are both checked.
