Automatic storage of event codes
The Micro-Speed® Smart-Move, Micro-Speed® CX™ and Micro-Speed® MX/MV™ models all automatically store the last four different types of event codes the drive has seen. They are stored in the Diagnostics memory locations E1, E2, E3, E4. Memory location E1 contains the most recent trip code (newer models also have a number in front of the code, indicating the number of times that type of trip has occurred). This history can help diagnosis a problem – including motor and other mechanical conditions.
