I have a Tachometer input for my spindle that
is looking for input from a Quadrature Encoder.
I do not care about reading the direction of rotation only the speed.
I hooked up a encoder I had here and only used the
output of the A channel and fed it into the A and B inputs.
It did appear to correctly read the speed once I set
the pulse rate that the software was looking for.
Is there a problem hooking it up this way?
I have done some reading on Quadrature Encoders
but have been unable to find an answer.
I could use two sensors but it is double
the parts for a simple speed reading.
Thank you
