Drive Fault Detection Overview, Continued
You can configure how you want some situations reported (drive
fault, warning, or ignored), while other situations are always reported
as faults. For the configurable faults, four parameters are provided:
Fault Select 1 (parameter 20), Warning Select 1 (parameter 21), Fault
Select 2 (parameter 22), and Warning Select 2 (parameter 23). For
information about these parameters, refer to Chapter 12,
Troubleshooting.
This section explains how some of the faults are caused and detected.
