STEUERSCHALTUNG ZUM ERZEUGEN EINER SCHNELL ZU VERAENDERNDEN ANALOGEN AUSGANGSSIGNALSPANNUNG UND MIT AUTOMATISCHER RUECKSTELLUNG IN EINEN NEUTRALEN BETRIEBSZUSTAND |
摘要 |
<p>A control circuit generates a variable analog output voltage in response to momentary closure of touch control means by an operator. The control level selected via the touch control means is sampled, digitized, digitally stored and reconverted to the analog output voltage for driving a motor at a commensurate speed. Selection of a different control level generates a correspondingly different digital value and thus a different analog output voltage. The selected control level and the corresponding analog output voltage may be maintained for an extended period of time until a new selection is made, or a different operating mode is entered. A mode change causes an automatic reset to a neutral operating condition (e.g., zero analog output voltage).</p> |
