Fault handling
To reset a fault manually, use the [FAULT RESET] key on the keypad. Return the drive to the run
condition by performing manual start or by forcing the RunRequest_I equal to "true".
Certain faults can be reset automatically if enabled by the auto fault reset enable (7120). Refer
to Table Auto resettable faults, for a list of auto resettable faults. These are fixed and not
adjustable. If reset is successful, the drive will return to the run state automatically only if the
RunRequest_I is maintained at the value "true". The [FAULT RESET] key of the keypad is also
used to acknowledge alarms.
