How to reduce acoustic noise or vibration in Danfoss DC Drives?
Acoustic noise or vibration can be caused by resonances in the motor/fan system. Check if noise and/or vibration have been reduced to an acceptable limit. Also, turn off overmodulation in parameter 14-03 Overmodulation. Increase resonance damping in parameter 1-64 Resonance Dampening.
What to do if there is a mains phase loss in Danfoss DC Drives?
If you're experiencing a mains phase loss with your Danfoss DC Drives, it's likely due to a missing phase on the supply side or a voltage imbalance that's too high. To resolve this, check the supply voltage to ensure all phases are correctly connected and balanced.
What causes short circuit in Danfoss VLT AutomationDrive FC 360 DC Drives?
A short circuit error in Danfoss DC Drives usually means there's a short-circuit either in the motor itself or on the motor terminals.
