8 Warnings and Alarms

8.1 System 

Monitoring

The monitors the condition of its input power, output, and
motor factors as well as other system performance
indicators. A warning or alarm may not necessarily indicate
a problem internal to the itself. In many cases, it indicates
failure conditions from input voltage, motor load or
temperature, external signals, or other areas monitored by
the frequency converter’s internal logic. Be sure to
investigate those areas exterior to the as indicated in the
alarm or warning.

8.2  Warning and Alarm Types

8.2.1 Warnings

A warning is issued when an alarm condition is impending
or when an abnormal operating condition is present and
may result in the issuing an alarm. A warning clears by
itself when the abnormal condition is removed.

8.2.2 Alarm Trip

An alarm is issued when the is tripped, that is, the 
suspends operation to prevent or system damage. The
motor will coast to a stop. The logic will continue to
operate and monitor the status. After the fault condition is
remedied, the can be reset. It will then be ready to start
operation again.

A trip can be reset in any of 4 ways:

•

Press [RESET] on the 

•

Digital reset input command

•

Serial communication reset input command

•

Auto reset

8.2.3 Alarm Trip-lock

An alarm that causes the to trip-lock requires that input
power be cycled. The motor will coast to a stop. The logic
will continue to operate and monitor the status. Remove
input power to the and correct the cause of the fault, then
restore power. This action puts the into a trip condition as
described above and may be reset in any of those 4 ways.

8.3  Warning and Alarm Displays

Figure 8.1

An alarm or trip-lock alarm will flash on display along with
the alarm number.
