If the motor does not move in the desired direction, the device switches off safely. Ideal for all applications where a safe direction of rotation is essential, such as automation processes, compressors, machine tools and wind turbines. The device allows up to four operating modes for different configuration of overfrequency, underfrequency, window range and direction of rotation. <\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Simple and time-saving start-up without PC<\/li><li> Direction of rotation monitoring fulfils Cat. 2 \/ PL d while retaining Cat. 4 \/ PL e for frequency monitoring <\/li><\/ul>\n\n\n\n<p>For more information, please visit: <a href=\"https:\/\/www.dold.com\/en\/company\/news\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"https:\/\/www.dold.com\/en\/company\/news\/ (opens in a new tab)\">https:\/\/www.dold.com\/en\/company\/news\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In addition to safe speed monitoring, the sensorless speed and frequency monitor UH 6937 of the SAFEMASTER S series now also offers safe monitoring of the phase sequence resp. direction of rotation [&hellip;]<\/p>\n","protected":false},"author":12,"featured_media":49356,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[8,716,1545],"class_list":["post-49353","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-automation-robotics","tag-automation","tag-monitoring","tag-rotation-motors"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.8.1 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Dold: Now with safe phase sequence resp. rotational direction monitoring - EXPO21XX.com NEWS<\/title>\n<meta name=\"description\" content=\"In addition to safe speed monitoring, the sensorless speed and frequency monitor UH 6937 of the SAFEMASTER S series now also offers safe monitoring...\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.expo21xx.com\/news\/dold-now-with-safe-phase-sequence-resp-rotational-direction-monitoring\/\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"Marcel Huegel\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"1 minute\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\/\/www.expo21xx.com\/news\/dold-now-with-safe-phase-sequence-resp-rotational-direction-monitoring\/\",\"url\":\"https:\/\/www.expo21xx.com\/news\/dold-now-with-safe-phase-sequence-resp-rotational-direction-monitoring\/\",\"name\":\"Dold: Now with safe phase sequence resp. rotational direction monitoring - EXPO21XX.com NEWS\",\"isPartOf\":{\"@id\":\"https:\/\/www.expo21xx.com\/news\/#website\"},\"primaryImageOfPage\":{\"@id\":\"https:\/\/www.expo21xx.com\/news\/dold-now-with-safe-phase-sequence-resp-rotational-direction-monitoring\/#primaryimage\"},\"image\":{\"@id\":\"https:\/\/www.expo21xx.com\/news\/dold-now-with-safe-phase-sequence-resp-rotational-direction-monitoring\/#primaryimage\"},\"thumbnailUrl\":\"https:\/\/www.expo21xx.com\/news\/wp-content\/uploads\/Banner_News_2023_02_600x600@2x.png\",\"datePublished\":\"2023-04-21T13:06:17+00:00\",\"author\":{\"@id\":\"https:\/\/www.expo21xx.com\/news\/#\/schema\/person\/bd95c8756a923fd2192f30b343b9c719\"},\"description\":\"In addition to safe speed monitoring, the sensorless speed and frequency monitor UH 6937 of the SAFEMASTER S series now also offers safe monitoring...\",\"breadcrumb\":{\"@id\":\"https:\/\/www.expo21xx.com\/news\/dold-now-with-safe-phase-sequence-resp-rotational-direction-monitoring\/#breadcrumb\"},\"inLanguage\":\"en-US\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/www.expo21xx.com\/news\/dold-now-with-safe-phase-sequence-resp-rotational-direction-monitoring\/\"]}]},{\"@type\":\"ImageObject\",\"inLanguage\":\"en-US\",\"@id\":\"https:\/\/www.expo21xx.com\/news\/dold-now-with-safe-phase-sequence-resp-rotational-direction-monitoring\/#primaryimage\",\"url\":\"https:\/\/www.expo21xx.com\/news\/wp-content\/uploads\/Banner_News_2023_02_600x600@2x.png\",\"contentUrl\":\"https:\/\/www.expo21xx.com\/news\/wp-content\/uploads\/Banner_News_2023_02_600x600@2x.png\",\"width\":266,\"height\":159,\"caption\":\"E.
