Danfoss Vlt Error Code — 2563

If you replaced the control card but did not update the firmware to match the power module, or vice versa, the drive may throw 2563 because it reads incompatible data structures.

The error code is not a standard system-level alarm or warning code for Danfoss VLT drives. Standard Danfoss VLT error codes typically fall within the range of 1 to 255 .
