User-defined fault 2

Hva betyr 25218 ?

This fault indicates that the 'Activate fault 2' function has been triggered within the flexible I/O configuration. The activation specifically occurred via the input trigger selected in parameter 0x2631:044 (P400.44). This fault type typically results in the motor being brought to a standstill.

• An external safety device or process sensor connected to the input (Parameter 0x2) activated, triggering 'Activate fault 2'.
• Incorrect wiring or a loose connection to the digital input specified for 'Activate fault 2' (Parameter 0x2).
• Persistent or transient signal on the configured input due to electrical interference or faulty cabling.
• Misconfiguration of the input trigger in Parameter 0x2, inadvertently selecting a constantly active signal.
• Failure of the digital input circuit on the drive's I/O board associated with 'Activate fault 2'.

1. 1

   Determine the specific digital input terminal linked to 'Activate fault 2' by checking Parameter 0x2.

2. 2

   Monitor the voltage state of the identified digital input terminal (e.g., X1.2) using an oscilloscope to detect unexpected transitions.

3. 3

   Check the operational status of the external sensor or switch connected to the input for proper functioning and physical integrity.

4. 4

   Verify the programming of Parameter 0x2 to ensure the input is configured correctly (e.g., positive or negative logic).

5. 5

   Temporarily disable the 'Activate fault 2' monitoring function in Parameter 0x2 to confirm if the fault originates from the input signal path.
