HJTrost Posted May 22 Share Posted May 22 I now have got my Power PMAC 465 Clipper to move my stages smoothly, with one odd feature: I have rotary encoders on the motors of my leadscrew stages with 2000 lines per rev, corresponding to 6 mm/rev of the screw. However, the counts reported by the Power PMAC are off by a factor 3.125 - 100,000 quadrature counts are reported at 24 mm instead of 75 mm. Motor[x].PosSf and its relatives are all set to 1.0. From using other controllers (PMAC2A/PC104, Turbo Clipper) on the same system I positively know that 75 mm is the correct answer. Are there any candidates among the many parameters that could be "used" to create such a discrepancy? Cheers, Jochen Quote Link to comment Share on other sites More sharing options...
