Original Press Release:
Anti-Hunt(TM) Eliminates Servo Dithering
QuickSilver Controls, Inc. in Covina, California announces advances in their Anti-Hunt feature. When Anti-Hunt is used, the SilverMax(TM) will go from closed loop (servo) to open loop after it reaches its target position. Think of it as "turning itself into a step motor." Anti-Hunt allows users to take advantage of a step motor's ability to stay still (not dither) while at rest, simultaneously providing servo control when moving. Although QuickSilver has had this feature for years, users now have the option of keeping the SilverMax in Anti-Hunt mode while it is moving. At low speeds, SilverMax can stay in Anti-Hunt mode as long as position errors are low.
Anti-Hunt is ideal for applications such as positioning a microscope, an antenna or a camera; when smooth control is required while stopped or at low speeds. Visit www.qcontrol.com for more details.
