Smaract Motion Controller

Driver module for Smaract SCU controller.

This module allows controls of linear SLC stages or rotary ones using the SCU controller

The smaract libraries must be known by the system, adding their location on the system path

class instrumental.drivers.motion._smaract.scu.SCU(inst=None, **kwds)

Class for controlling actuators from smaract using the SCU controller

Takes the device index and channel index as init parameters

move_to(value, move_type='rel')

Parameters:

• value ((float) position in steps) –

• move_type ((str) without sensor can only be 'rel' for relative motion fro a given number of steps) –
