After the fault is reset,the drive can be restarted. Note that some faults require a reboot of the control uniteither by switching the power off and on, or using parameter 96.08 Control board boot– this is mentioned in the fault listing wherever appropriate.Warning and fault indications can be directed to a relay output or a digital input/outputby selecting Warning, Fault or Fault (-1) in the source selection parameter. Seesections• Programmable digital inputs and outputs (page 30)• Programmable relay outputs (page 30), and• Programmable I/O extensions (page 31).

The logs can also be accessed (and reset) using the Drive composer PC tool.One of the logs contains faults and fault resets. The other log lists warnings and pureevents, as well as clearing entries. Both logs contain 32 most recent events. Allindications are stored in the event logs with a time stamp and other information.Auxiliary codesSome events generate an auxiliary code that often helps in pinpointing the problem.The auxiliary code is displayed on the control panel together with the message. It isalso stored in the event log details. In the Drive composer PC tool, the auxiliary code(if any) is shown in the event listing.Factory data loggerThe drive has a data logger that samples preselected drive values at 500-microsecond (default; see parameter 96.65 Factory data logger time level) intervals.Approximately 7000 samples recorded immediately before and after a fault are saved
