Description:
    Macros for the use of a 17T superconducting magnet controller from Birmingham (????).
Documentation:
    DESCRIPTION
    Use of the Birmingham superconducting magnet controller.

    SETUP
    In the config editor in the "Motor and Counter Device Configuration" page (hit "D") create a motor controller like follows:
    MOTORS          DEVICE          ADDR  <>MODE  NUM             <>TYPE
       YES          BIRMSM             -            1       Macro Motors
    Then create the macro motor: 
    Number: <>Controller           0: MAC_MOT

    
Unit/[Module/]Channel                 0/0 (first num is index num of controller)

    
Name                                 birm

    
Mnemonic                             birm

    
Steps per degree/mm                 10000

    
Sign of user * dial                     1

    
Backlash [steps]                        0

    
Steady-state rate [Hz]                  1

    
Base rate [Hz]                          1

    
Acceleration time [msec]                1

    
Motor accumulator                       0

    
Restrictions <>                      NONE

    


    
Dial = accumulator / steps

    
  High limit                      17.0000

    
  Current                          0.0000

    
  Low limit                      -17.0000

    
User = sign * dial + offset

    
  Offset                           0.0000

    
  `High' limit                    17.0000

    
  Current                          0.0000

    
  `Low' limit                    -17.0000

    It is advisable to set the backlash for the macro motors to 0.

    ATTENTION
    Channel numbers are :
    0 for magnet field
    1 for Current Temp Heat Exchanger
    2 for Current Temp Probe
    3 for Needle Valve Position
    4 for Needle Valve Pressure Target
    5 for Needle Valve Actual Pressure
    6 for helium level
    7 for atto position
