Experimental Physics and Industrial Control System

Hi Wolfgang et al,
This is a pretty common issue. At LCLS we use a custom version of the motor record that doesn’t support negative ERES, and neither do our ’smart' motors, so we usually have to fix it in hardware as Mark said. As a rule, if you can make sure
to keep the phases consistent from the beginning, that is the way to go and prevents problems down the road. Just my two cents.
Best regards,
Scott
Hallo,
I am new in epics motor record control and try to configure my first axis with encoder. I am now in trouble with an linear axis with encoder Pro (dex Maxnet Controller). Without encoder. the axis works fine. I activated encoder read out by adding PSE to the
init string, UEIP to yes and ERES to 5e-5, then the RBV field changes negative by the correct absolute value, when I move positive with TWF .1. I tried to set ERES negative to -5e-5 without any effect. Has somebody an idea how to change the sense of the encoder
readout?
Thank you very much
Wolfgang
