Network: user fault 2

What does 0x62A2 mean?

This fault is triggered when the "Activate fault 2" function is activated via the NetWordIN1 data word 0x4008:001 (P590.01). The underlying cause of "user fault 2" needs to be identified and rectified before the error can be reset.

• External control system (e.g., PLC, IPC) intentionally setting the 'Activate fault 2' bit within NetWordIN1 (0x4008:001) due to a detected process anomaly.
• Incorrect logic or programming in the external control system's application code, erroneously triggering the fault bit under normal operating conditions.
• Faulty input signal to the external control system that causes it to incorrectly activate 'Activate fault 2' in NetWordIN1.
• Intermittent communication issue on the industrial network (e.g., Profinet, EtherNet/IP) leading to corrupted NetWordIN1 data and accidental fault activation.

Click steps to track your progress.

1. 1

   Access the inverter's parameter P590.01 (NetWordIN1 mapping) and identify which bit is assigned to the 'Activate fault 2' function.

2. 2

   Review the external control system's (e.g., PLC) program logic that writes to the corresponding bit in NetWordIN1 (0x4008:001); debug and modify logic as necessary.

3. 3

   Use the inverter's diagnostic menu or a network monitoring tool to observe the real-time value of NetWordIN1 (0x4008:001) and identify when the fault bit transitions to active state.

4. 4

   Verify the integrity of the network connection (cables, connectors) and communication settings (e.g., IP address, subnet mask, device name) for reliable data exchange.

5. 5

   Check any external sensors or process conditions that feed into the PLC logic which could trigger 'user fault 2'; verify their calibration and operational status.
