PACS_Chopper_SFT_Cold_OpenLoop
// Purpose : SFT in Open Loop Mode (cold conditions) // Author : Markus Nielbock // Description : SFT cold 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, chopper is switched off and disabled // Diagnostic HK not running // Comments : Adapted from PACS_SPEC_Chopper_OpenLoop_MoveAbs_OBS.cus // Version : 1.0 // History : 1.0 12-10-2007 - BV: extracted procedure from observation by MN and added mois // comments //
