MVP 2023 Joe Tauser Posted January 7, 2019 MVP 2023 Report Share Posted January 7, 2019 Generally the first two inputs on the main control can be configured for a quadrature encoder. But you haven't given us any information on your system - do you have which PLC you'll use specified yet? What is the make and model of your shaft resolver? Joe T.

John_R Posted January 7, 2019 Report Share Posted January 7, 2019 Hmmm, No expert here, but years ago I had a couple of machines that used resolvers. If I recall they were not like encoders as they did not have a pulse output, but rather they had a two or three phase AC output and the PLC (old Giddings & Lewis) had special resolver modules. My understanding was that the controls compared the phase differences to "resolve" the rotational position of the device. I mainly remember what a pain they were to keep calibrated. I always thought they were pretty "old school" technology. JohnR Link to comment Share on other sites More sharing options...
MVP 2023 kratmel Posted January 7, 2019 MVP 2023 Report Share Posted January 7, 2019 Direct resolver connection to Unitronics PLС high speed inputs is not possible. Resolver to Digital Converter must be used. Like this: http://www.jvl.dk/files/_2011clean/pdf/ld038gb.pdf Link to comment Share on other sites More sharing options...
