If you are seeing this code, follow these steps to narrow down the issue:
This guide was compiled by industrial automation engineers with 15+ years of experience troubleshooting Danfoss VLT, PowerFlex, and Altivar drives in critical infrastructure.
A municipal water utility operated a Danfoss VLT HVAC FC 102 controlling a 75 HP pump. After a lightning storm nearby, the drive displayed Alarm 2563 every 2–6 hours.
Ensure that motor cables are properly shielded and grounded. Check that signal cables (0–10V or 4–20mA) are separated from high-voltage power lines to minimize EMI.
Probe the DC link voltage (terminals +UDC, -UDC). Look for: Danfoss Vlt Error Code 2563
For further assistance, you can download specific manuals from the Danfoss Service and Support page.
Inspect interlock wiring and safety switch contacts annually.
If you have a remote reset configured (e.g., terminal 18 or 29), trigger it. If the drive resets but fails again within 10 seconds, the corruption is persistent.
(often labeled as "IMC position error") within the drive's internal motion control logic. Understanding Error 2563: The Position Error If you are seeing this code, follow these
If the error clears, the cause was likely a one-time power glitch or ESD event. If it returns immediately or after a few minutes, proceed to the next steps.
To effectively troubleshoot Error Code 2563, follow these steps:
Disclaimer: Troubleshooting VFDs requires electrical knowledge. Always disconnect power and follow local safety regulations.
The remaining 10% involve systemic power quality or grounding issues that require professional on-site analysis. Ensure that motor cables are properly shielded and grounded
: If your drive is part of a larger system (like a REMAK HVAC unit), 2563 might be a proprietary system error rather than a native drive alarm.
There is no standard "Error Code 2563" listed in official 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).
A simple reset might get you running for a few hours, but without addressing the cooling or loading issue, you risk a catastrophic failure that takes down your entire line and produces expensive meltdown damage.
If you've followed these steps and the Danfoss VLT error 2563 persists, it is recommended to contact technical support or check the VLT documentation for your specific series. If you'd like, I can:
