hello..
any one could give me the actual application and difference of incremental and absolute rotary encoder?
i had encounter a steel rolling machine which uses as what they say an incremental encoder.., the machine now was inoperational due to it was on the alarm display:check machine rotary encoder.
anyone could give me some basic procedures, perhaps a standard procedures to test or diagnose the rotary encoder from defects and abnormalities?
my colleague test the output pulses of the unit, phase a, phase b, phase z and phase a', b' as well..but i doubt that while stall(not in motion)we got pulses on phases..does it mean that the encoder is not defective?
by the way, the unit is rated on 5 voltdc, 500 pulse where the ouput is conected to a control cards..not in PLC.
thanks..
