h08:30 Check FW#2 su W#1

La FW fa ancora dei rari episodi di stop toccando il connettore sulla FW e i suoi fili adiacenti. Sembra ceh siano i fili che vanno al connettore della board.

Smontiamo e Mike ribatte i punti per vedere se sono uoni i contati.

Disconnettiamo la FW#2 e ribattiamo i contatti

h09:20 Plug AGW#2 test FW#2 new commands

Stacchiamo AGW#1 e ttacchiamo AGW#2. Salviamo i dati della vecchia FW#2:
Parametri del driver MCBL Faulhaber:
grm    15100
gkn     1290
gpc     3000
gcc      410
gac     2000
gdec   30000
gsp     3000
ghosp    2000

gpor       9
gi        22  
gpp        8
gpd       10  
gci       40  

Parametri del processo SimpleMotorCtrl (da filterwheel2.conf):

MotorType: adc
Ratio: 327000   ( 1 filter)
CircleRatio:  1635000 (1 circle)
HomingOffset: 163500
CruiseSpeed: 3000
Acceleration: 2000
HomingSpeed: 2000
Unidirectional: 0

Mettiamo poi il nuovo set fornitoci dai tecnici Faulhaber per poter comandare la FW#2 di ARGOS:
rm      2300    mOhm    Motor resistance
kn      3447    rpm/V   Speed constant
lpc     970     mA      Peak current limit
lcc     970     mA      Cont. current limit
ac      3000    1/s^2   Acceleration
dec     3000    1/s^2   Deceleration
sp      3000    rpm     Maximum speed
hosp    1000    rpm     Homing speed

(die folgenden Werte benoetigten noch Tuning,
sind nur "nach Gefuehl" eingestellt;
mit denen hat Dennis jedoch gemessen ;-) )
por     3               Proportional term
i       5               Integral term
pp      5               Gain of position controller
pd      1               D-term of position controller
ci      40              I-term of current controller

MotorType     argoswheel
Ratio          225958
CircleSteps 1129790
HomingOffset    0

CruiseSpeed  3000
Acceleration   2000
HomingSpeed 1000
Unidirectional  0

L'unica modifica rispetto ai parametri della Faulhaber è il cambio del termine proporzionale da (por) da 5 a 3 per ridurre le vibrazioni durante il funzionamento.

La nuova configurazione funziona con la ruota di Jesper ed ha un'accuratezza di 10 counts su 1200000 (1arcsec*10)

Il pick up del TT è un dicroico che fa passare lambda<laser in foro che trasmette un campo di +/-3asec sul TV col FINZ

HOWTO change filterwheel parameters for a new filterwheel

1) Remove old filterwheel
2) Turn on the WFS including filterwheels. The removed filterwheel will give an error during homing (or maybe it could just report that everything is fine and in position zero).
3) Stop the "Filter wheel ctrl 2" process
4) Open a socket to the controller: on W#1, open a terminal on wfssx and give the following command:

telnet ts8 3106

On W#2:

telnet ts839dx 2106

5) Give a test command on the telnet connection to see if the socket is working:

POS [Enter]

the motor will answer with the current position, probably zero.

6) Give all the commands that start with "g", with no argument. I.e. "grm [Enter]". The controller will reply with the current value. Save all such values into a text file, like it was done above.

6) Give the entire set of commands given above for the new Faulhaberm motor: rm 2300 [Enter], etc. Verify correct entry using the "grm" command. Repeat for all other commands.

7) Save the new command set in the permanent memory, with the EEPSAV command

8) Update the $ADOPT_ROOT/conf/wfs/current/processConf/filterwheel2.conf file with the new parameters (MotorType, etc.)

9) Start the Filter Wheel Ctrl 2 process and test the whell

10) If it works, reboot the entire AGW and test it again (to see if everything has been correctly saved).

h14:20 FW#2 W#2 smontata per sostituzione

Smontiamo la FW#2 dal W#2 e spostiamo i filtri su quella ARGOS

Controlliamo i filtri della vecchia FW:
Pos 0: vuoto
Pos 1: 850-40 (9336)
Pos 2: 800-40
Pos 3:700-10 (Thorlabs FB700-10 1-2-07)
Pos 4: Vuoto

Nella FW di ARGOS replichiamo le stesse posizioni mettendo il pickup di ARGOS su Pos 4
