ID #: KETV-001

Required setting accuracy : 50 encoder counts

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

Final Mechanical Assembly and Testing Results

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.

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 the drive the stage towards the forward limit.
