AI<MIN FUNC
ABB · ACS800
What does 8110 mean?
The analogue input signal to the ABB ACS800 drive has fallen below its set minimum limit. Depending on parameter 30.01 (AI<MIN FUNCTION), this condition can cause the drive to trip on a fault and coast to a stop, or generate a warning while setting speed to a constant value or the last operating speed.
Common Causes
- The analogue input signal (e.g., for speed or torque reference) drops below the configured minimum limit, such as 0.5V or 1mA.
- Breakage, loose connections, or short circuits in the analogue input signal wiring.
- Faulty sensor or transducer providing the analogue input signal to the drive.
- Incorrect setting of the analogue input minimum limit in parameter group 13 ANALOGUE INPUTS (it must be 0.5V/1mA or above).
- Incorrect setting of parameter 30.01 (AI<MIN FUNCTION) for the desired drive reaction.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Measure the actual analogue input signal (voltage or current) at the ABB ACS800 drive's input terminals (e.g., AI1, AI2) and verify it is above the set minimum limit.
- 2
Check the integrity of the wiring from the sensor/source to the drive's analogue input terminals; look for loose connections, breaks, or shorts.
- 3
Verify parameter 30.01 (AI<MIN FUNCTION) is set correctly for the desired drive reaction (FAULT, CONST SP 15, LAST SPEED, or NO).
- 4
Inspect the sensor or transducer providing the analogue input signal for proper operation, calibration, and its own power supply.
- 5
Ensure that the analogue input minimum setting in parameter group 13 ANALOGUE INPUTS is set to 0.5 V (1 mA) or above, as specified.
