9.6.3 AutoFailReset function
The AutoFailReset function serves to automatically reset the latching "Fault" and "TroubleQSP"
errors as well as the latching "WarningLocked" warning.
The "latching" term means that the effect on the inverter remains active even after the error cause
has been removed.
To reset latching errors and warnings, the following options are available:
• Manual reset
• with device command C00002/19
(activated by Low-High edge)
• by a Low-High edge at the bResetFail input of the LS_DriveInterface
(the "FailReset" control
bit in the control word must be parameterised with a value of "1").
•Automatic reset
• using the AutoFailReset function.
