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
