Alarms, faults and system messages
9
The inverter has the following diagnostic types:
● LED
You can obtain an overview of the inverter state locally at the Control Unit LED.
● Alarms and faults
Alarms and faults have a unique number. The inverter displays the numbers on the
Operator Panel and via STARTER - or signals them to a higher-level control.
If the inverter no longer responds
Due to faulty parameter settings, e.g. by loading a defective file from the memory card, the
inverter can adopt the following condition:
● The motor is switched off.
● You cannot communicate with the inverter, either via the Operator Panel or other
interfaces.
In this event proceed as follows:
● Switch-off and switch-on the Control Unit power supply three times.
● If the inverter signals the fault F01018, carry out the corrective actions for this fault shown
in section List of faults (Page 256).
F0101
8 can only be acknowledged by switching the CU on and off again.
