SEW encoder

Dear ,

If you have facility to remove the encoder from the motor then try to remove it along with it's end connector, and then check it on Oscilloscope, check for all the signals coming , first see on what voltage it is working, and then apply it on the appropriate pin number and find out what signals are coming on corrosponding pin number, by rotating the encoder manually. see whether all signals are coming properly or not and then also find out for the reference mark on oscilloscope. Also there is one more instrument from Heideinhain it will be more helpful to you to check about your encoder.
