Comment to ETMY IP position check (8453)

[Takahashi, Lucia, Eleonora]

Today we went at the Y-end station to finalize the IP recovery position. 

Here a brief report of what was done:

1) we swapped the stepper motor driver and we verified that H1 motor was working properly. 

2) we put back  the IP close to (0,0,0) by using the motors

3) Since the malfuntioning of H1 motor was due to the driver, we changed the channel assigned to H1 motor from Ch1 to Ch5.

4) we close the IP loops and we recovered  the OPLEV signal by movin g the BF_Y.

 

Next to do: we have to reconfigure the motor script to give the correct assignement of the motors.
