matt.briciugeorgfischer.c Posted January 24, 2018 Share Posted January 24, 2018 Hello, I am running a program which gathers data through the Delta Tau Plot feature. Once I upload the data, I made a plot of motor(1) Actual position and motor(1) cmd position on the left axis and time on the horizontal axis. When I save the data into a .txt file, the file gives a list like: Time(sec) Motor[1] Act Position Motor[1]CmdPosition 0.00000000000000000 -1806515.47722567000000000 -1806520.06591749000000000 0.00250000000000000 -1806519.47722567000000000 -1806520.06591749000000000 0.00500000000000000 -1806519.47722567000000000 -1806520.06591749000000000 0.00750000000000000 -1806517.47722567000000000 -1806520.06591749000000000 0.01000000000000000 -1806520.47722567000000000 -1806520.06591749000000000 Can someone please explain what units the actual and command position are in? Thanks, Matt Link to comment Share on other sites More sharing options...
Faraday MC - Tony Posted January 25, 2018 Share Posted January 25, 2018 They are in PMAC Motor Units. It will be encoder counts with the default settings, but they might have been scaled into engineering units with one of the scale factors. You need to subtract Motor[x].HomePos to get the correct positions. Link to comment Share on other sites More sharing options...
