Project: DEIMOS
Stage: Tent Mirror
ID #: KDTM-001A
Engineer: J. Osborne

Mechanical Description of Stage: Mirror is tilted by +/- 30 arc-seconds.  A piezo-electric linear acutator is used with flex-pivots on the mirror.  No limit switches or fiducials.

Electronic Description of Stage: Piezo controller from PI (Physik Instruments). Part #_____. Interfaces with Lantronix terminal server via RS-232 connection.

Required setting accuracy:

1. Speed, temperature, accuracies, electrical power, pressurized air, lubricant, coolant, N2 purge, ...

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.

NOTES:

Electronic Drawing(s) #

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 towards the forward limit.
