ICD_FSSTranslationStage

FSS Translation Stage

Control of the XY translation stage used as support for the FSS Detector, including motor, tachometer, encoder and reference switches.

The control is deployed on the Sensor LCU.
The device is connected to the Terminal Blocks Z16 for the X-axis and Z17 for the Y-axis.

The motor control is a pure SW interface: the target position and velocity are passed to the Motion Controller via the VME bus. The motor control software is provided by ESO.

FSS Translation Stage interfaces:

The connection layout and pin assignment is given in Annex 1 VLT-DWG-ESO-15154-1787
