VIA Signal Fault

Hva betyr E-18 ?

This fault signifies that the analog input signal at terminal VIA has dropped below the minimum level defined by parameter F633 ([Loss of VIA]), indicating a potential loss of speed reference signal or sensor input.

• The analog signal at terminal VIA is below the configured threshold.
• Incorrect setting of parameter F633 ([Loss of VIA]).
• Loss of signal from the sensor connected to VIA.

1. 1

   Measure the analog signal voltage/current at terminal VIA.

2. 2

   Rectify the cause of the signal loss (e.g., sensor, wiring).

3. 3

   Check parameter F633 ([Loss of VIA]) and verify it is set correctly for the application.
