Alarms, Faults And System Messages; Operating States Indicated On Leds - Siemens SINAMICS G120 Function Manual

Alarms, faults and system messages

The inverter has the following diagnostic types:
● LED
● Alarms and faults
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
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
F01018 can only be acknowledged by switching the CU on and off again.

Operating states indicated on LEDs

The LED RDY (Ready) is temporarily orange after the power supply voltage is switched-on.
As soon as the color of the LED RDY changes to either red or green, the LEDs on the
Control Unit indicate the inverter state.

You can obtain an overview of the inverter state locally at the Control Unit LED.
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.
