How to fix AMA check Unom and Inom error on Danfoss VLT AutomationDrive FC 302 DC Drives?
If you encounter issues with AMA check Unom and Inom on your Danfoss DC Drives, it means the settings for motor voltage, motor current, and motor power are wrong. Check the settings in parameters 1-20 to 1-25.
How to resolve AMA low Inom error on Danfoss VLT AutomationDrive FC 302 DC Drives?
If you encounter AMA low Inom on your Danfoss DC Drives, it means the motor current is too low. Check the settings.
Why am I getting a temperature input error on my Danfoss DC Drives?
If your Danfoss DC Drives displays a temperature input error, the temperature sensor is not connected.
What to do if 24 V supply is low on Danfoss VLT AutomationDrive FC 302?
If the 24 V supply is low in your Danfoss DC Drives, which is measured on the control card, check for a defective control card.
How to fix '10 Volts low' error on Danfoss VLT AutomationDrive FC 302?
If your Danfoss DC Drives shows '10 Volts low', it could be due to a short circuit in a connected potentiometer or improper wiring. Remove the wiring from terminal 50. If the warning clears, the problem is with the wiring. If the warning doesn't clear, replace the control card.
What does '1.8 V supply low' mean on Danfoss VLT AutomationDrive FC 302 DC Drives?
If the 1.8 V DC supply is low on your Danfoss DC Drives, it indicates that the 1.8 V DC supply used on the control card is outside of allowable limits. Check for a defective control card.
What to do if brake check failed on Danfoss VLT AutomationDrive FC 302?
If the brake check failed on your Danfoss DC Drives, it means the brake resistor is not connected or not working. Check 2-15 Brake Check.
What to do if option module configuration has changed on Danfoss DC Drives?
If the option module configuration has changed in your Danfoss DC Drives, verify that the configuration change was intentional and then reset the unit.
What causes DC overvoltage in Danfoss DC Drives and how to fix it?
If your Danfoss DC Drives display a DC overvoltage error, it indicates that the DC-link voltage exceeds the limit. Here are some potential solutions:* Connect a brake resistor.* Extend the ramp time.* Change the ramp type.* Activate the functions in parameter 2-10 Brake Function.* Increase parameter 14-26 Trip Delay at Inverter Fault.If the alarm/warning occurs during a power sag, consider using kinetic back-up (parameter 14-10 Mains Failure).
What does illegal FC configuration mean for Danfoss VLT AutomationDrive FC 302?
If your Danfoss DC Drives displays an illegal FC configuration, it means the control card and power card are incompatible. Contact the Danfoss supplier.
