Generic HEPI Position Loops Installed on HAM4

HughR, HugoP,

We installed the rencently-designed HAM-HEPI generic position loops on HAM4 last Friday. We had tried in the past but there was an issue with the way they were saved as a .mat file, before being loaded by the commissioning scripts. This has been fixed, and the updated controllers, and scripts are available under the SVN:

Generic Position Loops:
/ligo/svncommon/SeiSVN/seismic/HEPI/Common/Generic_Pos_Loops/Position_Loops/HAM_HEPI_Generic_Position_Loops_23_May_2014.mat

Plots:
/ligo/svncommon/SeiSVN/seismic/HEPI/Common/Generic_Pos_Loops/Plots/

Design Scripts:
/ligo/svncommon/SeiSVN/seismic/HEPI/Common/Generic_Pos_Loops/Scripts/

 

 
The related commissioning scripts of HAM4-HEPI (steps) can be used as templates for the installation of the generic position loops on the other HAM-HEPI units.
 
Next step is to try designing similar position loops for BSC-HEPI
