High levels of electrical noise or improper grounding can disrupt the sensitive digital signals on the control board, triggering a false internal fault.
Check that the drive and motor are grounded to a common, low-impedance ground point. 3. Inspect for Physical Damage
Control card failure or DSP communication error. Danfoss Vlt Error Code 2563
If you encounter this error, follow these steps in order to determine if the drive can be recovered or if it requires a replacement part. 1. Perform a Power Cycle (Cold Boot)
The most frequent cause is a physical defect or component failure on the control card itself. High levels of electrical noise or improper grounding
Ensure that all (motor and control) are properly bonded at both ends with a 360-degree connection.
Since 2563 is often a triplock alarm, a standard reset won't work. Disconnect the AC mains supply to the drive. Inspect for Physical Damage Control card failure or
The drive will "trip lock," meaning it will not allow a simple reset until the power is cycled and the root cause is addressed. Common Causes of the Fault
(this allows the DC link capacitors to discharge fully). Reconnect the power and check if the error persists. 2. Verify Grounding and Shielding
