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

ATTENTION! All scrapers have a mechanical gearbox (20:1.5); every 20 turns of the axis the Scraper moves by 1.5 mm.
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.

Operative mode
Before making any movement, it is necessary to put the axis in Operational Mode using the "Oper" key 
.
Oper key (similarly to the magnet control); this operation allows to give current to the phases of the single motor.
It also guarantees safety on any unwanted movements once the set has been found.
"Flags for all elements" allows operation on all axes simultaneously....
Enter the value and press "IN" or "OUT" in the desired direction

of the counter (Position [mm]), and of the setting field.
If the procedure is not successful, that is:
1. hourglass (clessidra) removed
2. encoder value is not zero
3. "End Run OUT" in the OFF state
the system warns with an error detectable by the log.
This procedure can be repeated, unless an "overcurrent" state occurs, due to the motor malfunction.
Warning, this procedure misaligns the values written on DBFile relating to the home position of the resistive encoder (absolute),
causing a relative misalignment between the "Position" and "Absolute Position" values.
IMPORTANT! After this operation, it is recommended to report to the Control Group which will update the configuration files.
...
Otherwise contact the Control Group.Save, load, and apply configurations
To recover a configuration (it will be inserted in the Saved column [mm])...
To apply the set in the Saved column [mm] to all the axes simultaneously....
