What does 2 mean?

The voltage or current signal on terminal 53 or 60 has dropped below 50% of its preset minimum scaling value (parameter 309 or 315). This indicates a problem with the analog input signal that the drive uses for control or feedback.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3
