Chapter 9 Troubleshooting and
Countermeasures
There are two types of messages that appear under abnormal conditions in a variable frequency
speed control system, one is an alarm message and the other is a fault message. When there is an
alarm, the system can still continue to work, but will light up the alarm indicator and trigger an
audible and visual alarm. When a fault occurs, the system will automatically shut down, while
lighting the fault indicator and triggering an audible and visual alarm. Only after the fault is
completely removed and the "Fault Reset" button is pressed, the fault can be removed and the system
can be turned on again. All alarms and faults are recorded in the information system and can be
viewed by clicking on the "History" button.
