User-defined fault 1

Hva betyr 25217 ?

This fault indicates that the 'Activate fault 1' function has been triggered within the flexible I/O configuration. The activation specifically occurred via the input trigger selected in parameter 0x2631:043 (P400.43). This fault type typically results in the motor being brought to a standstill.

• External process condition or sensor activated, triggering the input configured for 'Activate fault 1' in Parameter 0x2.
• Incorrect wiring or intermittent connection to the digital input terminal assigned to 'Activate fault 1' (Parameter 0x2).
• Spurious electrical noise on the input line configured in Parameter 0x2, causing an unintended fault trigger.
• Misconfiguration of Parameter 0x2, leading to the selection of an inappropriate or always-active input source.
• Internal hardware fault on the specific digital input channel used for 'Activate fault 1'.

1. 1

   Identify the physical digital input terminal associated with 'Activate fault 1' as configured in Parameter 0x2.

2. 2

   Measure the voltage level at the identified digital input terminal (e.g., 24VDC or 0VDC) to verify its state when the fault occurs.

3. 3

   Verify the status and operation of the external sensor or device connected to this input, ensuring its output is as expected.

4. 4

   Review Parameter 0x2 settings to confirm the correct input source and logic (e.g., normally open, normally closed) are selected.

5. 5

   Temporarily disconnect the external signal from the digital input terminal and observe if the fault clears, indicating an external signal issue.
