Connecting Quadrature Encoder to Single-Ended Channel: Advice

[jxlee]

I have one quadrature encoder with A- A+ and B- B+ Signal, but my driver is a single-ended encoder channel?
Can i just connect either the A+ and B+ or A_ and B- signal to the single-ended encoder channel?
Please advise.
Thanks

Could you please post more details? You don't drive an encoder.

Now i have a motor with quadrate encoder from MicroE-Mecury Model 1510-S with A- A+ and B- B+ Signal, and i want use my Advanced motion controller (BE15A8) to drive the motor. From the driver its only have Single-ended encoder A and B. So can i just connect the A+ and B+ from the encoder direct to the controller?

Beside that is it possible direct connect the encoder signal to amotion controller and didnt go through the driver? Please advise. Thanks

the + and - means that the signals are differential pairs

to me it sounds like it is possible to use it by connecting the - pairs to your encoder... someone sent this to me, i hope that it can help you

Standard polarity signals consist of a “positive” level, pulse or edge in RS-422 input mode. (This
means the + input has a higher, more positive, voltage than the – input.) In single-ended logic-level
input mode, standard polarity consists of a “negative” level, pulse or edge. (This means the input is
at logic zero, about 0.7 volts or less.)
This definition of polarity is by convention. TTL signals have been historically “active low.” Many
sensors and opto-couplers are “active low.”

For as far as I can reproduce from your information, you have an dual channel encoder. basically this means channel A and B are shifted a few degrees from each other. In this way, you can determine the rotation direction (clockwise or counterclockwise).

Try powering the encoder and see if you can get a pulse signal from either A+ and A- or B+ and B-. there's some deviation in the logic signals you get from an encoder, but experience tells me hooking up A+ and A- to an osciliscope should do the trick.
