A782

FEN temperature

ABB · ACS880 Primary Firmware

What does A782 mean?

An error in temperature measurement from a KTY or PTC sensor connected to encoder interface FEN-xx has occurred. This could be due to incorrect parameter settings or using an unsupported sensor type (e.g., KTY on FEN-01). Inaccurate temperature feedback risks motor overheating or improper thermal protection.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Use parameter 91.10 (Encoder parameter refresh) to validate any changes in the settings.

  2. 4

    If using a KTY sensor on FEN-01, switch to a PTC sensor or a different encoder interface module, as FEN-01 does not support KTY.
