D-line Notes: default motor configuration

As D-line runs in many configurations, but has only 16 channels of motor control available (at best), it makes more sense to program a flexible interface into spec, rather than attempting to run in a static configuration. This is done by chosing suggestive names for the various functions of xz stages, goniometers, etc., saving their parameters in the config file, but only assign actual motor channels to the motors that are used in a specific experiment.

NOTE: check the current settings! Most motors are 4A, however, there are some 1A motors  around !!


Basic Motors

Slit System

The ADC slit system is run on a serial line independent of CAMAC/StepPak and is a given. Both physical and macromotors (for gap and offset) are configured.

• The macro package "slits.mac" contains further essential configuration parameters.
• The macro "mdrive_stat" reads all current motor settings from the MDrives.
  

Sample stages

• xz stage: samx, samz
• heavy duty sample stage with long travel: rockx, rockz
  
• xz stage plus goniometer: samx, samz, samth, samtilt (D1 GISAXS stage)
• precision xz stage plus goniometer: xsam, zsam, thsam, phisam (G1 GISAXS stage)

Flightpath, beamstop, detector

• xz stage for fligh path: fpx, fpx
  
• xz stage for beamstop: bsx, bsz
• xz stage for detector: detx, detz

Capillary set-up

• capillary mount: capx, capz
  
• beam block: blkx, blkz

DAC motors

digital-to-analog converters signals in Volts are treated like motors in SPEC
currently only motor dactest configured

DIO Channels

digital input/output also via motor config
