Warnings/alarm messages and corrective actions

The table below gives the drive's warnings and
alarms and indicates whether the fault trip locks the
drive. After a Trip Lock Fault, the input power must
be removed, the cause of the fault corrected, and
input power restored to reset the drive. A Trip can
be reset manually in any one of three ways.
1. Pressing the keypad key RESET
2. A digital input
3. Serial communication
In addition, an automatic reset may be selected
in parameter 405, Reset function which will
reset all non-trip lock faults.

Wherever an "X" is placed under both Warning and
Alarm in the table below, this means that a Warning
precedes the Alarm. It can also mean that it is possible
to program whether a given fault is to result in a
Warning or an Alarm. This is possible, for example,
through parameter 128, Motor thermal protection.
After a trip, the motor will be coasting and the drive's
Alarm and Warning indications will flash. If the fault is
removed, only the Alarm will flash. After a reset, the
drive will be ready to start operation again.
In the following detailed descriptions of warning
and alarm messages, corrective actions to resolve
the condition are recommended.
