Alarms, faults and system messages
9
The converter has the following diagnostic types:
• LED
The LEDs at the front of the converter immediately inform you about the most important
converter states.
• Alarms and faults
Every alarm and every fault has a unique number.
The converter 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
• Identi󹪝cation & maintenance data (I&M)
If requested, the converter sends data to the higher-level control via PROFIBUS or PROFINET:
– Converter-speci󹪝c data
– Plant-speci󹪝c data
