Fault - Analog input 1
Lenze · i550 Protec Drive
Hva betyr 28801 ?
The monitoring function for analog input 1 has been triggered, as configured via parameters 0x2636:008 (P430.08) and 0x2636:009 (P430.09). This indicates an issue with the signal connected to analog input 1, potentially an out-of-range or missing signal.
Vanlige årsaker
- Analog input signal (e.g., 0-10V, 4-20mA) from the external sensor connected to Analog Input 1 is outside the configured limits (P430.08, P430.09).
- Open circuit in the wiring to Analog Input 1 (e.g., a broken wire, loose terminal), causing the signal to drop below the lower threshold.
- Short circuit or incorrect wiring to Analog Input 1, leading to a signal above the upper threshold or an invalid signal.
- Faulty external sensor or transducer providing an incorrect or out-of-range analog signal to Analog Input 1.
- Damage to the Analog Input 1 hardware on the drive's I/O board, preventing accurate signal interpretation.
Reparasjonssteg & Sjekkliste

- 1
Disconnect the external signal from Analog Input 1 terminals (e.g., X3.1, X3.2) and measure the voltage or current at the terminals.
- 2
Measure the output voltage or current of the external sensor directly at its terminals to verify its function and output range.
- 3
Using a calibrated multimeter, measure the resistance of the wiring from the sensor to Analog Input 1 to detect open or short circuits.
- 4
Check parameters 0x2636:008 (P430.08) and 0x2636:009 (P430.09) to ensure the analog input monitoring thresholds are set correctly.
- 5
Apply a known, stable reference signal (e.g., 5VDC, 12mA) to Analog Input 1 to test the drive's input circuit response.
