Alarms, Faults And System Messages; Operating States Indicated On Led - Siemens Sinamics CU240D-2 DP Operating Instructions Manual

Alarms, faults and system messages

The inverter has the following diagnostic types:
● LED
The LEDs at the front of the inverter immediately inform you about the most important
inverter states.
● System runtime
The system run time is the total time that the inverter has been supplied with power since
the initial commissioning.
● Alarms and faults
Every alarm and every fault has a unique number.
The inverter signals alarms and faults via the following interfaces:
– Fieldbus
– Terminal strip with the appropriate setting
– Interface to the BOP-2 or IOP-2 operator panel
– Interface to STARTER or Startdrive
● Identification & maintenance data (I&M)
If requested, the inverter sends data to the higher-level control via PROFIBUS or
PROFINET:
– Inverter-specific data
– Plant-specific data
