Warnings and Alarms
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 400,
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
117, 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.
No.
