Charlie, Hrand and Matt looked into the reasons why some positioners were not working during some of the cold tests.
Previous investigations had shown that the positioners had a frequency of 0.0000 set.
It was not clear when and why this happened.
After restarting the system the error would occure sometimes and sometimes not.
Since Number 1 was not working at all before these actions (despite Msim restarts and setFrequenciesAll script) it is concluded that the failure lies outside of MSIM.
No further action to debug electronics since we are waiting on new FPGA version.
