Danfoss Vlt Error Code 2563 May 2026

There is no standard "Error Code 2563" listed in official Danfoss VLT manuals for common series like the FC 101, FC 102, or FC 302. Most Danfoss VLT alarms use a 1 or 2-digit format (e.g., Alarm 13 for Overcurrent).

Manual Initialization: If the code persists and prevents operation, you can perform a factory reset by holding [Status], [Main Menu], and [OK] while powering up. Danfoss Vlt Error Code 2563

1. Intermittent "A2563" on the LCP (Local Control Panel) that appears only during heavy load ramping.
2. The drive suddenly trips and displays "Alarm 2563" immediately after a power blip or brownout.
3. The LCP screen freezes or shows garbled characters before the alarm triggers.
4. Parameter changes are not saved. You set P-04 to a value, but after power cycle, it reverts.
5. The drive hums or oscillates strangely before tripping, but no external motor fault exists.

Is Error 2563 Field Repairable?

The short answer is no for most facilities, unless you have SMD rework stations and access to Danfoss service parts. Here’s why: There is no standard "Error Code 2563" listed

It is important to distinguish the Danfoss industrial drive error from the automotive P2563 code. If you are seeing "P2563" on an OBD-II scanner, it refers to a Turbocharger Boost Control Position Sensor issue in a vehicle engine, not a fault in a variable frequency drive.

Step 3: Parameter Review (If the drive will power up without running)

2. Loose or Oxidized Control Card Connectors

The Danfoss VLT architecture uses a stackable design: the control card (MK102) plugs into the power card via two 20-pin ribbon connectors. Vibration or thermal cycling loosens these connectors. Oxidized pins cause intermittent SPI bus errors, which manifest as Code 2563.
