EXTERNAL FLT
ABB · ACS800
What does 9000 mean?
A fault condition has been reported by an external device connected to the ABB ACS800 drive. This information is typically transmitted via a programmable digital input to the drive. This protection is linked to programmable Fault Function 30.03.
Common Causes
- An actual fault condition in an external device (e.g., external overload relay trip, safety gate open, pressure switch activation).
- Incorrect configuration of parameter 30.03 (EXTERNAL FAULT), leading to misinterpretation of the digital input signal.
- Wiring issue on the digital input used for external fault monitoring (e.g., loose connection, broken wire, incorrect voltage level).
- External device fault contact chattering or intermittent operation.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Check all external devices connected to the drive's digital inputs for faults and resolve any issues (e.g., reset external overloads, close safety gates).
- 2
Verify parameter 30.03 (EXTERNAL FAULT) setting to ensure the correct digital input is selected and the fault logic (normally open/closed) matches the external device.
- 3
Check the wiring of the digital input associated with the external fault for continuity, secure connections, and correct voltage level (e.g., 24VDC) when the external device is healthy.
- 4
Clear the fault on the external device before attempting to reset the drive.
