Distributor data for this exact part lists it as a 2 HP drive with an internal control panel and a NEMA 1\/IP21 enclosure, making it suitable for panel installation in industrial environments. The device supports both constant-torque and variable-torque motor control, enabling use in applications such as fans, pumps, conveyors, and machine tools that require precise speed regulation. ABB’s lifecycle documentation designates the ACS501 family as legacy\/obsolete, noting that the product line has been in obsolescence since early 2008, which can affect parts availability and technical support. As part of the older ACS500 series, the ACS501-002-4-00P2 provides core motor control functions, ramping, and protection features with the option to pair with packs that extend communications or functionality. For engineers evaluating replacements, this model represents a historic ABB solution that may be more challenging to source and service today compared with newer ABB drive families offering contemporary diagnostics and modern interfaces.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656861221166,"sku":null,"price":648.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c7eff678-17f5-4fb4-a62a-20cf38a21ae1.jpg?v=1769463870","url":"https:\/\/plgautomation.com\/products\/abb-acs501-002-4-00p2-variable-frequency-drive","provider":"PLG Automation ","version":"1.0","type":"link"}
