Troubleshooting with the PROFIBUS DP

Overview
There are three types of diagnostic display:
● LEDs
● Alarm Numbers
● Diagnostic parameters.
Diagnostics using alarm numbers
If a Operator Panel (OP) is fitted to the Control Unit and a alarm or fault condition occurs, the
OP will display the appropriate alarm or fault number.
If an alarm occurs, the alarm number will be displayed and the inverter will continue to run,
although it is possible that it may run in an unexpected manner depending upon the alarm
condition.
If a fault occurs, the fault number will be displayed and normally the inverter will be stopped.
