Quicker, easier diagnostics and less downtime in drive investigations
process interruptions in variable- speed drive applications. Drive trips occur to protect the machinery from faults that could cause damage and extended loss of production time. The diagnostic features and displays are designed to provide a highly effective set of monitoring variables which can be programmed to give early warnings to prevent trips happening, or to take evasive action to avoid the problem altogether. They also provide maintenance

triggers based on various operating data to remind operators when servicing needs to be carried out on the motor or machine. When problems occur, the diagnostic features provide clear instructions about the event and how to return the plant to service in the shortest time. The ABB drives’ keypad features
icons, hints, tips and help screens to show users where to look to investigate process events, helping find causes more quickly. The keypad screen displays flashing icons and pictures to attract attention and to show the reason for the event. Scrolling screens on the keypad give the user a better view of multiple events and hints. All events are displayed with help text to identify the probable cause. Advice is given to guide the user to the part of the application likely to have caused the event, or the parameter setting that
range of diagnosis and keypad display features from ABB cuts the time needed to investigate
The PC tool from ABB can generate a full support package, containing all the event data, the parameter files and other useful information
needs to be amended. Useful data from within the drive parameters are collected together for easy viewing. These include fan runtime counters and basic diagnostic words that allow efficient signalling between the drive and the process logic controller. A PC-based support package
allows the maintenance engineer to get further help from ABB when needed. If a drive trips, or the customer is unable to resolve the issue themselves, they will need to contact ABB. The PC tool can generate a full support package, containing all the event data, the parameter files
and other useful information. The support package can be e-mailed to ABB to help it diagnose the issue. It provides all the necessary data in one go, avoiding the need for several visits, saving time and giving a faster diagnosis. More information from www.
