3.3.1.42. NXpositioner¶
Status:
base class, extends NXobject
Description:
A generic positioner such as a motor or piezo-electric transducer.
Symbols:
No symbol table
- Groups cited:
none
Structure:
@default: (optional) NX_CHAR
Declares which child group contains a path leading to a NXdata group.
It is recommended (as of NIAC2014) to use this attribute to help define the path to the default dataset to be plotted. See https://www.nexusformat.org/2014_How_to_find_default_data.html for a summary of the discussion.
name: (optional) NX_CHAR
symbolic or mnemonic name (one word)
description: (optional) NX_CHAR
description of positioner
value[n]: (optional) NX_NUMBER {units=NX_ANY}
best known value of positioner - need [n] as may be scanned
raw_value[n]: (optional) NX_NUMBER {units=NX_ANY}
raw value of positioner - need [n] as may be scanned
target_value[n]: (optional) NX_NUMBER {units=NX_ANY}
targeted (commanded) value of positioner - need [n] as may be scanned
tolerance[n]: (optional) NX_NUMBER {units=NX_ANY}
maximum allowable difference between target_value and value
soft_limit_min: (optional) NX_NUMBER {units=NX_ANY}
minimum allowed limit to set value
soft_limit_max: (optional) NX_NUMBER {units=NX_ANY}
maximum allowed limit to set value
velocity: (optional) NX_NUMBER {units=NX_ANY}
