Scrapers Dafne Layout
Hardware Layout
Hardware Front-end
The motors are controlled by drives called "MOTION SYSTEM INTERFACE DEVICE" assembled by "RAMTRON Computing".
The box is equipped with two Technosoft drives IDM240-5EI or IDM640-8EI , to operate 2 Stepper Motors

Operations on Scrapers assembly with RAMTRON drive
For relative movements, the positive steps (by Technosoft Software, Manual-Controller Labview, or Low-Level Devil) the Scraper must enter the chamber.
Relative movement : positive Steps → Scraper IN

Two operating modes can be used without distinction. One called Absolute Movement and one called Relative Movement (optimized for fine movement).
...
Absolute Movement
Relative Movement
Enter the value and press "IN" or "OUT" in the desired direction
Single-axis homing
The "Home" button is positioned in the Advanced Display as shown in the figure.
During the Homing phase, the Scrapers performs an automatic procedure that brings it into a completely open state, followed by a reset of the relative encoder,
...
After the procedure, which takes a maximum of 2 minutes, see if the situation has been reached as shown in the figure:
Otherwise contact the Control Group.Save, load, and apply configurations
To recover a configuration (it will be inserted in the Saved column [mm])
Per recuperare una configurazione (verrà inserita nella colonna Saved[mm] )
To apply the set in the Saved column [mm] to all the axes simultaneously.End-run

Devil Description "Dante Control System" (DCS)
The system was born to operate with scrapers that have the machine name SCHXXYYY, but the class that manages them is the MOV class,
therefore it has the following MOVXXYNY nomenclature.

Classes: MOV, SER (not implemented; see "Note")

Technosoft IDM module programming
EasyMotion Studio is an integrated development environment for the setup and motion programming of Technosoft intelligent drives and motors.
The output of EasyMotion Studio consists of a set of setup data and a motion program, which can be downloaded to the EEPROM of your Technosoft intelligent drive / intelligent motor,
or saved onto your PC for later use.
