Analog Input Below Minimum Function

Hva betyr 8110 ?

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).

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.
