sutty Posted October 31, 2018 Share Posted October 31, 2018 Hi! We are running a PPMAC ARM V2.3.2.5 on Phase/Servo/RTI 32/16/2 kHz, 2x3 cascaded motors (6 motors) Running the application w/o Lookahead doesn't cause any problems. But with Lookahead active (10ms Segmentation, 130 Segments) once in a while (every several minutes up to every several hours) run-time error occurs. Unfortunately, Coord[x].Ldata.Status always tells a 1 after such run-time error - it does not give any useful information. What is very confusing to us is that a few milliseconds before run-time error occurs Sys.RtIntTime peaks for the duration of only 1/16 of a millisecond!! Another characteristic is that as long Sys.RtIntTime stays below 750 us run-time error does not show up at all. Augmenting Sys.PreCalc does not help. Removing RtiCplc does not help neither. At last whenever a run-time error happens it almost always shows this kind of pattern. Today we started testings with V2.4.1.2 - results will follow. Questions: 1. Why would Sys.RtIntTime peak for less than 70us?! 2. Any suggestions which PPMAC-Variables to trace to get more useful data?
