Wed Mar 6 15:33:14 2019, Drive Team- Ino&Thierry&Armand, Telescope Operations, General, Test High Speed Drive,
|
Test at 60% maximal speed from -90 to 0
Check of the FW discharge : No error (FW 2 : 95% FW1 : 100%)
Test
at 60% maximal speed from -90 to 270
Check of the FW discharge ==> Error (FW 2 : 90 % FW1 : 100%)
Drive stops at 250
degree.
Power consumption = 60kw

|
On Thrusday :
new movements at 45% from -90 to 270 have been done.
No possible movement at 60% because the FW and UPS
issues are not solved yet
Ino will back on site when HITACHI team will be on site for FW maintenance
Tests at 60% will
be done to validate (or not) the correction applied by Hitachi team.

Fri Mar 8 09:25:22 2019, Drive Team- Ino&Thierry&Armand, PLC + Control Software debugging, Software, Tracking debug and setup,
|
Tracking procedure has been debugged from the GUI-MOS (OPCUA Server with tracking plugin)-PLC
Still some improvments to apply
but globally the procedure is running well.

|
Regulation of the motors (PID) for slow and fast tracking and motor oscillations.
Implementation and Debugging of the Semi-Expert
control software for the drive.
GUIs + MOS plugin (OPCUA Server)
Results are quite encouraging in good wheather
condiftions.
additionnal tests in different (wind) conditions are envisaged to validate completly the process

On Wenesday morning (27/03/19) :
With Holger and Robert (MPI) , many telescope "park in/park out" operations have been
performed in order to refine the positionning in the acces tower and at the elevation locking bolt
Holger and Robert applied many mechanical modifications on the acces tower to make the telescope park operations very smooth |

Thu Apr 18 21:07:20 2019, Drive Team- Ino&Thierry&Alessandro, Telescope Operations, , TESTS Parkout Parkin for fixing the bolt issue,
|
Different ParkOut and Parkin done with different values for testing the torque limitation.
By decreasing the torque and the
position , the parkin failed because we are not in the CSS locking sensor (in locking position)
By setting back the original values, th
parkin is ok but the bolt cannot be properly inserted.

Thu Apr 18 21:21:25 2019, Drive Team- Ino&Thierry&Alessandro, Telescope Operations, Hardware, Elevation limit switch issue, 
|
The 2 swicthes are too far from the target at 56.48 elevation. The sensor have been tuned in parkin position and the distance was
correct (2mm) and at 56.48 is about 10mm. (impossible to tune correctly the sensor and the atrger has to be tuned) |

Debugging of the tracking sequence :
PLC sequence : trajectory tracking data correctly managed
PLC tuning : regulation OK ==> need to refine.
Tracking
algorithm :
Changes in Drive.ccp to allow azimuth negative values.
Tracking duration : even by changing the duration of he tracking |
