Why Danfoss DC Drives power on with red light?
- JJames ChavezAug 27, 2025
If your Danfoss DC Drives show 'Power On' and the indicator is red, this typically indicates an IP Address Conflict. Resolve the IP conflict.
Why Danfoss DC Drives power on with red light?
If your Danfoss DC Drives show 'Power On' and the indicator is red, this typically indicates an IP Address Conflict. Resolve the IP conflict.
What to do for option detection issues in Danfoss VLT HVAC Drive FC 102?
If your Danfoss DC Drives detects a change in the option layout, enable option layout changes to apply the change.
What to do if the motor is not running on Danfoss DC Drives?
If the motor does not start in your Danfoss DC Drives, check the motor connection and the service switch. Apply mains power if using a 24 V DC option card. Press [Auto On] or [Hand On] to run the motor, depending on the operation mode. Ensure a valid start signal is applied. Deactivate the motor coast signal by applying 24 V on terminal 27 or program this terminal to no operation. Program the correct reference signal source and check the wiring and scaling of terminals.
What to do if Danfoss DC Drives display Live Zero Error?
The 'Live Zero Error' warning or alarm on your Danfoss DC Drives appears if programmed in parameter 6-01 Live Zero Timeout Function and the signal on one of the analog inputs is less than 50% of the minimum value programmed for that input. Check the connections on all analog mains terminals. Also, check control card terminals 53 and 54 for signals, using terminal 55 as common. Ensure that the drive programming and switch settings match the analog signal type.
What causes motor overload temperature in Danfoss VLT HVAC Drive FC 102?
To address a motor overload temperature issue in Danfoss DC Drives: * Check for motor overheating. * Check if the motor is mechanically overloaded. * Check that the motor current set in parameter 1-24 Motor Current is correct. * Ensure that the motor data in parameters 1-20 to 1-25 is set correctly. * If an external fan is in use, check that it is selected in parameter 1-91 Motor External Fan. * Running AMA in parameter 1-29 Automatic Motor Adaptation (AMA) tunes the frequency converter to the motor more accurately and reduces thermal loading.
What to do if brake check failed on Danfoss DC Drives?
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 does a parameter error mean on Danfoss DC Drives?
If your Danfoss DC Drives display a parameter error, it indicates that the parameter is out of range. Set the affected parameter to a valid value.
What causes overload of digital output Terminal 27 in Danfoss VLT HVAC Drive FC 102?
Overload of digital output Terminal 27 is caused by the load connected to terminal 27 or remove short-circuit connection. Check 5-00 Digital I/O Mode and 5-01 Terminal 27 Mode.
How to troubleshoot a motor not reaching maximum speed on Danfoss DC Drives?
If the motor is not reaching its maximum speed using Danfoss DC Drives, program the correct frequency limits. Also, ensure that the reference input signal is scaled correctly by adjusting the settings.
Why is the motor speed unstable in my Danfoss VLT HVAC Drive FC 102?
If the motor speed is unstable in your Danfoss DC Drives, check the settings in parameter group 1-6* Load Depen. Setting. For closed loop operation, check settings in parameter group 20-0* Feedback.
