Analog Input Below Minimum Function

What does 8110 mean?

An analogue input signal has fallen below its set minimum limit, which can cause the drive to react by either tripping or setting the speed to a predefined value. This warning indicates a potential loss of critical feedback or reference signal, which could lead to unsafe or unintended operation if not addressed.

• Broken wire or loose connection in the analog input signal circuit (e.g., 4-20mA loop, 0-10VDC source).
• Faulty external sensor or transducer providing the analog input (e.g., pressure sensor outputting 0mA).
• Incorrect scaling of the analog input parameter (e.g., P09-01, P09-02 for minimum/maximum limits).
• External power supply for the analog sensor failed (e.g., 24VDC supply for current loop).
• Incorrect configuration of the analog input type (e.g., P09-00 set for current input when voltage input is used).

Click steps to track your progress.

1. 1

   Measure the voltage or current at the drive's analog input terminals (e.g., AI1, AI2) using a multimeter.

2. 2

   Verify the external sensor or transducer connected to the analog input is powered and producing its expected output signal.

3. 3

   Check drive parameters P09-00 (Analog Input 1 Type), P09-01 (Analog Input 1 Minimum), and P09-02 (Analog Input 1 Maximum) for correct configuration.

4. 4

   Inspect the wiring from the analog sensor to the drive's analog input terminals for continuity and secure connections.

5. 5

   Temporarily bypass the external sensor and apply a known, stable analog signal (e.g., 5VDC from a power supply) to the drive's input to test the drive's response.
