Hi All

I have an encoder with several wires. On the encoder there is a diagram which is showing different pulse shapes with difference of angle. My question is where we use these different signals and how


Thanks

Re: Encoder Working

Hi ibrar. well first two of them are for power supply the encoder; generally black for negative and red for positive in the range of 5 to 12 VDC. The others lines vary from manufacturer and type of encoder but may be two (A signal and A complementary) or four (A and B and A complementary and B complementary).
The meanning of these signals are the A signal is the reference and the B signal is 90 degree delayed from A signal. These delay is for clockwise or counterclockwise direction detect, if the A signal is 90 degrees ahead to B then the direction is clockwise ; but if B signal is ahead then counterclockwise direction is present.
Be happy :D
