By following this guide, you minimize downtime, avoid unnecessary drive replacement, and restore reliable motor control. If you’ve successfully resolved Error 2563 using this article, leave your experience below to help other technicians in the field.

Because Error 2563 is an internal hardware-level fault, the causes are usually found within the drive’s internal circuitry rather than the external motor wiring:

Use a multimeter set to AC voltage:

Error code 2563 on a Danfoss VLT drive indicates a "Measurement error" or "Measurement fault" in the drive's control card. This error typically occurs when the drive's control card is unable to perform accurate measurements, which can affect the drive's ability to control the motor.

In plain English: The brain of the drive (control card) and the muscle of the drive (power card) cannot agree on the rules of operation, so the drive shuts down to prevent erratic switching which could destroy the IGBT module.
