Title: Double HSC on single encoder Fx2424
Post by: cch1955 on April 22, 2015, 03:49:00 PM

I have an application where it would be helpful to have two separate quadrature HSC channels counting from the same encoder input.

One counter would maintain absolute position and the other an incremental resetting counter. I could reset either without effecting the other.

I am thinking just putting the A/B signals into pins 1&2 for HSC1 and jumpering the inputs from HSC1 to the inputs of HSC2.

Any problem with this?

Thanks.

It does sound like a workable connection as long as the NPN outputs from the encoder is able to sink at least 10mA of current in order to properly drive the two NPN inputs in parallel to low voltage to turn the inputs on.
