1. CEA DSM Irfu July 19th 2013-Françoise Gougnaud - Status of EPICS control for ECCTD 1 Françoise Gougnaud Irfu/SIS

2. CEA DSM Irfu Slow tuning system = stepper motor Chosen motor: Phytron VSS 52 Stepper drive: our requirements –COTS boards –remote intelligence,i.e. not on the IOC –Ethernet communication if possible –easily scalable and configurable for hardware and software –EPICS support –Or possibility to use EPICS streamdevice July 19th 2013-Françoise Gougnaud -2

3. CEA DSM Irfu Only 2 solutions were considered Delta tau –Not convenient Nexeya Midi-ingenierie BMAC –Nexeya is a sound French company –BMAC already used at Irfu –could be used for slits or other motorisations Intent on looking at other solutions in the near future July 19th 2013-Françoise Gougnaud -3

4. CEA DSM Irfu Delta tau: finally not convenient Delta tau: 2 possibilities –UMAC (Power PMAC) Independant system with CPU, Ethernet EPICS support –Geobrick A robust support in the EPICS community A new version with embedded Linux can synchonise complex motions for several motors too sophisticated for our tuning systems Furthermore is too expensive July 19th 2013-Françoise Gougnaud -4

5. CEA DSM Irfu BMAC module version BMAC board version –BMAC crate can accommodate up to 12 boards (or 4 or …) on the crate –possible control of the motor up to 50 m cable –communication through Ethernet Slow tuning system: MIDI-INGENIERIE BMAC July 19th 2013-Françoise Gougnaud -5

6. CEA DSM Irfu BMAC Motion control board or module: some specifications Current 2.5 A (whereas DFMC 1.8A) 256 µsteps Dynamic current adjustment Encoder feedback ROHS Voltage BMAC 45V good speed performances 8 reconfigurable digital I/Os –limit switches, home positioning Automatic limit switch handling July 19th 2013-Françoise Gougnaud -6

7. CEA DSM Irfu BMAC Motion control board or module: some specifications 1 analog input can be used as generic remote I/Os or in order to synchronize motion with another device No external power supply needed Position reset on encoder index July 19th 2013-Françoise Gougnaud -7

8. CEA DSM Irfu An EPICS driver based on streamdevice is in progress but difficulties have been encountered Presentation by Adelino Gomes About EPICS software July 19th 2013-Françoise Gougnaud -8

9. CEA DSM Irfu BMAC prices For instance, for a configuration of 200 axes distributed over 10 crates: 3500 + 9*2000 + 200*300 = 91500 euros ~450 euros per axe July 19th 2013-Françoise Gougnaud -9

10. CEA DSM Irfu Fast tuning system with a NOLIAC piezoelectric actuator NAC2015-Hxx has been chosen by Guillaume Devanz –The piezo controller system has not been chosen yet Requirements –easily scalable and configurable –Ethernet communication –EPICS support already developed –Or simple to develop July 19th 2013-Françoise Gougnaud -10

11. CEA DSM Irfu A multichannels configuration of amplifiers and function generators has to be defined 2 solutions are being studied currently –modified amplifier PI E-508.OE –The modifications made are on the voltage and the current: 220 volts max peak current 2A average current 100 mA –amplifier E-618.20G Solutions for piezo controller July 19th 2013-Françoise Gougnaud -11

12. CEA DSM Irfu These amplifiers modules can be installed on a 19 ’’ crate in twos or fours TCP/IP communication A discussion is in progress with PI to specify the configuration but we encounter some difficulties to get all the precisions and documentation we want Solutions for piezo controller July 19th 2013-Françoise Gougnaud -12

13. CEA DSM Irfu Advantages of Irfu/EPICS solutions for stepper motor and piezo This architecture solution can be controlled by cPCI or µTCA or … : not control boxes dependant Easily scalable solution: – boards on a crate to control motors –modules on a crate to control piezos Not expensive July 19th 2013-Françoise Gougnaud -13

14. CEA DSM Irfu RF power control Specific to Saclay installation We have started some meetings to define the different signals –EPICS control –PLCs control July 19th 2013-Françoise Gougnaud -14

15. CEA DSM Irfu EPICS Communication and Siemens PLCs Siemens PLCs –Architecture defined by Jean S7plc chosen for communication between EPICS and PLCs July 19th 2013-Françoise Gougnaud -15
