SYSTEM DIAGNOSTICS
8.7.1
Controller Diagnostics
The MV3000e Controller provides diagnostic information which can be accessed by use of the optional Drive
Data Manager
(Keypad). The drive conditions for which diagnostic information is available are:
•
drive status;
•
warning of a problem;
•
fault condition;
•
trips.
The controller includes a group of LEDs (Light Emitting Diodes) shown in Figure 8–1 to provide an indication of
the four statuses listed above. All of the diagnostic information, and some of the helpful hints for fault
diagnosis, are detailed in the MV3000e Getting Started Manuals T1676 or T2002 (for AEM systems).
