A06401 — Infeed: Transformer data identification/test mode selected/active

Alarm A06401 tells you that a transformer data identification type or a transformer test operation has been selected or is currently active on the infeed. It accompanies the selected or running function rather than reporting a hardware problem. Which identification or test the drive means is encoded in the alarm value the drive writes to r2124.

• A transformer data identification run or a transformer test operation has been selected, or is currently being executed on the infeed.

1. No measures are necessary: the drive withdraws this alarm by itself once the transformer identification has expired.

• The drive stores the alarm value in r2124; the manual instructs you to interpret it as a decimal number.
• 11 — identification type 1 selected for transformer data (automatic determination of the magnetizing inductance).
• 12 — identification type 2 selected for transformer data (automatic determination of transformer phase shift and gain correction).
• 13 — identification type 3 selected for transformer data (determination of the total leakage inductance of the transformer during line data identification).
• 101 — test mode 1 selected.
• 102 — test mode 2 selected.

• r2124 — alarm value: read it as a decimal number to see which transformer identification type or test mode is selected or active.
• p5480 (Transformer magnetization mode) — the related transformer magnetization setting to which the manual cross-references under this alarm.

No acknowledgement and no restart are required. The manual states that the alarm is automatically withdrawn after the identification has expired, so it disappears by itself once the transformer data identification finishes.
