Cred ca m-am prins: masoara rotatia axului cu acel encoder si compara cu cea ideala data de quart:
The electronic controller unit compares the signals incoming from the high precision rotary encoder mounted onto the RA shaft with the time signal of its quartz oscillator. Any deviations of the angular velocity of the RA shaft from the prescribed drive rate, are compensated by feedback regulation in real time by accelerating or slowing down the drive.
Dar asta totusi presupune aliniere polara.
