LIMIT STOP SERVOCONTROL SYSTEM

Unidirectional feedback around a servoamplifier clamps the gain of the amplifier when the position feedback potential indicates the approaching of a stop. The clamping is in response to an amplifier output potential of a polarity that drives the servoed device into the stop, and is inoperative when...

Zusammenfassung:	Unidirectional feedback around a servoamplifier clamps the gain of the amplifier when the position feedback potential indicates the approaching of a stop. The clamping is in response to an amplifier output potential of a polarity that drives the servoed device into the stop, and is inoperative when the amplifier is of a polarity to drive the servoed device away from the stop. Full gain is therefore available when driving away from the stop. Increased accuracy is achieved, eliminating all position loop errors, by utilizing position feedback potential as a summing potential to control the operation of the clamping loop.
