  1. What is going on with motion control at DiamondMotion Control Workshop Ronaldo Mercado Controls Group Diamond

  2. Controllers in use • Mostly Delta Tau Geo Brick • A few generations, VME based on some beamlines • Packaged in a different enclosure for Diamond’s electrical standard • Except for insertion devices • Legacy, in the accelerator • OMS maxV • OMS VME58

  3. Drivers in use • Mostly tpmac model 2 • Also tpmac model 3 • oms non-asyn • oms asyn (by Nick Rees/Austen Rose) • pmac driver – support for power pmac • Needed for the mapping applications

  4. Motor record notes (1) • MRES – demands in integers • vs modern controller

  5. Motor record notes (2) • Logic in the motor record • The motor record does not transmit demands if going beyond the limits Biggest problem: • “New Target Monitoring” NTM • Made worse when using jittery motors • Demands from high level are not sent through • Problematic in case of a diffractometer • Current work-around: “Direct transfer” – demands sent to a separate record connected to the asyn port and driver, bypassing the motor record.
