10 Warnings and Alarms
10.1 System Monitoring
The frequency converter 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
frequency converter 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 frequency converter as indicated in the
alarm or warning.
10.2 Warning and Alarm Types
Warnings
A warning is issued when an alarm condition is impending
or when an abnormal operating condition is present and
may result in the frequency converter issuing an alarm. A
warning clears by itself when the abnormal condition is
removed.
Alarms
Trip
An alarm is issued when the frequency converter is
tripped, that is, the frequency converter suspends
operation to prevent frequency converter or system
damage. The motor will coast to a stop. The frequency
converter logic will continue to operate and monitor the
frequency converter status. After the fault condition is
remedied, the frequency converter 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 keypad
•
Digital reset input command
•
Serial communication reset input command
•
Auto reset
An alarm that causes the frequency converter to trip-lock
requires that input power is cycled. The motor will coast to
a stop. The frequency converter logic will continue to
operate and monitor the frequency converter status.
Remove input power to the frequency converter and
correct the cause of the fault, then restore power. This
action puts the frequency converter into a trip condition as
described above and may be reset in any of those 4 ways.
