For each setting, performs nturns *OPEN LOOP* movements of 360 degrees (default = 3). Open loop movement means that the wheel is driven for a given time, depending on the size of the movement and the rate. Consequently, the movement might finally not be of the expected size. === Photometer filter wheel === || || Script || TCL || Parameters || Comments || || 1 || PACS_Phot_HK_Setup_OBS || || || || || 2 || PACS_Phot_Fil_Diaghk_Setup_OBS || || || || || 3 || CONF_phot_fltw_param_OBS || Yes || rate,drive_current,threshold || || || 4 || PACS_Phot_Fil_Current_Loop_OBS || No || nturns : #turns of the FW/current setting || || || 5 || PACS_Diaghk_Reset_OBS || || || || || 6 || PACS_SAFE_MODE.tcl || || || || == Rate == The following test aims at checking the feasability and behaviour stability of the FWs operated at higher rates (= higher speed).
