The 'eatDrives - VFD help' app provides quick access to alarm descriptions of Eaton drives. In a second you get a full alarm description, troubleshooting guide and even a link to the latest user manual. App greatly helps by commissioning and service giving you the necessary information when you need it and where you need it. It is small but really feature-full application. A professional tool for professionals, must have in your First Aid Kit. Currently supported drives: H-MAX, HVX9000, LCX9000, M-MAX, MVX9000, NFX9000, PowerXL DA1, PowerXL DC1, PowerXL DE1, PowerXL DG1, SC9000, SLX9000, SPX9000, SVX9000. The app is in English. For most popular drives the main alarms descriptions are also available in Chinese, French and Spanish. Free version is fully functioning but is limited with only one randomly chosen drive. If you like the app, you can unlock all the drives by means of in-app purchase. DISCLAIMER This app IS NOT affiliated with Eaton Corporation or any of its affiliates.
