Danfoss Vlt Error Code 2563 Exclusive Jun 2026

and free from conductive dust or excessive moisture by maintaining proper panel ventilation and filtration.

: Look at the Local Control Panel (LCP) on the drive itself. It will likely show a more standard alarm (like "ALARM 13" or "ALARM 14") alongside the 4-digit code.

The system coasts to a stop, or in some cases, the load might drift downward.

Probe the DC link voltage (terminals +UDC, -UDC). Look for: Danfoss Vlt Error Code 2563

The best way to handle an error like 2563 is to prevent it from happening in the first place. An effective preventative maintenance plan can help you protect your valuable drives:

Several factors can lead to the occurrence of Error Code 2563 in a Danfoss VLT drive. Some of the common causes include:

Separate communication lines from motor power cables by at least 20 cm (8 inches). Prevention and Maintenance Tips and free from conductive dust or excessive moisture

One such fault is . Understanding what this code means, why it occurs, and how to systematically troubleshoot it is essential for minimizing system downtime and preventing hardware damage. What is Danfoss VLT Error Code 2563?

When contacting Danfoss support or a local distributor, have the complete drive model number, serial number, and the specific error code 2563 ready. This information is vital for a fast and accurate diagnosis.

Error Code 2563 on a Danfoss VLT drive generally points to a or, in many cases, a "Checksum Error" in the EEPROM, internal memory, or between the control card and power card. The system coasts to a stop, or in

Brake Resistor Shorted Error Type: Critical Fault Applicable Units: VLT AutomationDrive FC 302, VLT HVAC Drive FC 102, VLT Aqua Drive FC 202

If your VLT has an option card installed (e.g., Profibus, Ethernet/IP, CANopen), it might be causing a communication conflict. Power down the drive. Remove the communication option card. Power up the drive again.

Open the drive cover and locate the option card (Slot A, Slot B, or Slot C depending on your VLT model).

When a VLT drive enters a braking state (decelerating a load quickly), it pumps excess energy generated by the motor back into the DC bus. To prevent overvoltage, this energy is diverted to a brake resistor to be burned off as heat. Error 2563 triggers when the drive measures the resistance of the connected brake resistor and finds it is significantly lower than the calculated or expected value, or effectively zero ohms.
