What to do for an inrush fault in Danfoss DC Drives?
If your Danfoss DC Drives are showing an inrush fault, it means too many power-ups have occurred within a short time period. Let the unit cool to operating temperature.
What does a parameter error mean on Danfoss VLT AutomationDrive FC 301 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 an external fan fault on Danfoss VLT AutomationDrive FC 301 DC Drives?
If you are experiencing an external fan fault with your Danfoss DC Drives, the fan warning function checks if the fan is running/mounted. Check for proper fan operation. Cycle power to the frequency converter and check that the fan operates briefly at start-up. Also, check the sensors on the heat sink.
How do I fix an internal fan fault on Danfoss VLT AutomationDrive FC 301 DC Drives?
If your Danfoss DC Drives are showing an internal fan fault, the fan warning function is a protective function that checks if the fan is running/mounted. Check for proper fan operation. Cycle power to the frequency converter and check that the fan operates briefly at start-up. Also, check the sensors on the control card.
What to do if Danfoss DC Drives reach a torque limit?
Regarding torque limit issues with Danfoss DC Drives, if the motor torque limit is exceeded during ramp-up, extend the ramp-up time. If the generator torque limit is exceeded during ramp-down, extend the ramp-down time. If torque limit occurs while running, increase the torque limit. Also, check the application for excessive current draw on the motor.
What to do if Danfoss DC Drives show an over current error?
If you are experiencing an over current error with your Danfoss DC Drives, it might be due to shock loading or quick acceleration with high-inertia loads. First, remove the power and check if the motor shaft can be turned. Also, verify that the motor size matches the frequency converter and that the motor data is correctly set in parameters 1-20 to 1-25.
Why is the heat sink temp high on my Danfoss DC Drives?
If your Danfoss DC Drives are reporting a heat sink temperature issue, it means the maximum temperature of the heat sink is exceeded. Check for the following conditions: * The ambient temperature is too high. * The motor cables are too long. * Incorrect airflow clearance above and below the frequency converter. * Blocked airflow around the frequency converter. * Damaged heat sink fan. * Dirty heat sink.
What does control word timeout mean on Danfoss DC Drives?
If you're experiencing a control word timeout with your Danfoss DC Drives, it means there is no communication to the frequency converter. To resolve this, check the connections on the serial communication cable, increase parameter 8-03 Control Word Timeout Time, check the operation of the communication equipment, and verify that proper EMC installation was performed.
How to troubleshoot motor thermistor overtemp in Danfoss VLT AutomationDrive FC 301 DC Drives?
If you are getting a motor thermistor overtemp warning on your Danfoss DC Drives, check whether the thermistor is disconnected. Also, check for motor overheating and if the motor is mechanically overloaded. When using terminal 53 or 54, ensure the thermistor is correctly connected between either terminal 53 or 54 (analog voltage input) and terminal 50 (+10 V supply), and that the terminal switch for 53 or 54 is set for voltage. If using terminal 18, 19, 31, 32, or 33 (digital inputs), ensure the thermistor is correctly connected between the digital input terminal used (digital input PNP only) and terminal 50.
What causes DC under voltage in Danfoss VLT AutomationDrive FC 301?
If you are experiencing a DC under voltage error with your Danfoss DC Drives, check that the supply voltage matches the drive voltage. You may also need to perform an input voltage test and a soft-charge circuit test.
