PACS Chopper_SFT_Warm_OpenLoop
// Purpose : SFT in Open Loop Mode (warm conditions) // Author : Markus Nielbock // Description : SFT warm for FM1 chopper in open-loop mode. All 3 coils are // operative. The chopper is commanded between -20 mA and +20mA // in steps of 4 mA. // The first part consists of chopper deflections equivalent to // commanded chopper coil currents between 0 and +/-20 mA, // alternating between positive and negative values. Absolute // position commanding is used. // The second part consists of a ramp of chopper deflections // between -20 and +20 mA, commanded in relative steps of 4 mA. // Finally, the chopper returns to its zero position. // Preconditions : PACS switched-on in spectroscopy mode, chopper is switched // off and disabled, diagnostic HK not running // Comments : Adapted from PACS_Chopper_SFT_Cold_OpenLoop_OBS.cus // Version : 1.0 // History : 1.0 12-03-07 creation by MN // : 2.0 13-02-08 Made into a proc to be called by // "obs" PacsEng_Chpper_SFT_Warm_OpenLoop // Removed declaration of myOBSID
