Project: DEIMOS
Stage: CCD Focus
ID #: KDCF-001A
Engineer: D. Cowley (T. Freeman)

Mechanical Description of Stage: UHV linear Drive driven by Galil motor through a Berg slip clutch. Estimated travel +/- 1mm.

Electronic Description of Stage: Driven by Galil Controller #1 - Stage "E"

Required setting accuracy :

1. Speed, temperature, accuracies, electrical power, pressurized air, lubricant, coolant, N2 purge, ...
2. Primary (inner) and secondary (outer) limits. These can be magnetic, optical, or physical contact

1. Uphill defined as motor (or driven end of shaft) in lowest position

1. "Coarse" if from optical interupter, "Fine" if from an encoder index pulse. Home is defined as zero counts.
2. Primary limits signal the controller to stop motion. Secondary limits cut motor power and require intervention to move out of them.
3. Positive (+) motor drive moves focus stage toward the front of the dewar.

Sign conventions are such that a positive motion of the motor turns the motor in a CW direction as viewed from the drive shaft looking back into the motor, and will drive the stage to the forward limit (toward the window).
