Hi Frank,

You would want the digital encoder outputs not analog. Differential signals (A+,A-,B+,B-) are preferred because they are less noise sensitive and can be connected right to Kanalog's screw terminals. If you only have single ended signals (A,B) they can be connected directly to KFLOP (bypassing the differential to single ended receivers on Kanalog). Unplug JP5 from Kanalog and feed the encoders into KFLOP there. A terminating resistor to ground of around 150 ohms will help dampen signal ringing. Another option is to use cable modules that convert single ended signals to differential signals. I think USDigital and Digikey sell these for $10~15.

KFLOP's encoder inputs count at a maximum of 1.25 MHz. Configure the Axis Channel as input type Encoder and set the InputChan0 setting for the encoder input that it is wired to. JP5 has encoder inputs 4 through 7.

Regards

Hey,

I found a match cheaper one;
http://www.stappenmotor.nl/Datasheets/CNC%20lineare%20encoder/CNC%20lineare%20encoder.pdf

But it has only a A and B signal no - signals.
Can you give me the settings for those 3 options?

Thank you,
