What causes 10 Volts low error in Danfoss DC Drives?
A '10 Volts low' error in Danfoss DC Drives can be caused by a short in a connected potentiometer or improper wiring of the potentiometer. Remove the wiring from terminal 50. If the warning clears, the problem is with the customer wiring. If the warning does not clear, replace the control card.
What does parameter error mean on Danfoss DC Drives?
If your Danfoss DC Drives displays a parameter error, it means the parameter is out of range.
How to troubleshoot tracking error on Danfoss DC Drives?
If you're experiencing a tracking error with your Danfoss DC Drives, it means the difference between the set point value and the actual value has exceeded the limit. Investigate the mechanics around the load and motor.
What does it mean if the brake check failed on Danfoss VLT HVAC Drive FC 102?
If the brake check failed on your Danfoss DC Drives, it means the brake resistor is not connected or not working. Check parameter 2-15 Brake Check.
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 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 thermistor over temp in Danfoss VLT HVAC Drive FC 102 DC Drives?
A motor thermistor over temp error in Danfoss DC Drives can be caused by several factors. Check for motor overheating and if the motor is mechanically overloaded. When using terminal 53 or 54, check that the thermistor is connected correctly between either terminal 53 or 54 (analog voltage input) and terminal 50 (+10 V supply). Also check that the terminal switch for 53 or 54 is set for voltage. When using digital inputs 18 or 19, check that the thermistor is connected correctly between either terminal 18 or 19 (digital input PNP only) and terminal 50. Check 1-93 Thermistor Source selects terminal 18 or 19.
How to fix a short circuit in Danfoss VLT HVAC Drive FC 102 DC Drives?
If your Danfoss DC Drives indicate a short circuit, it means there is short-circuiting in the motor or motor wiring. Remove the power to the frequency converter and repair the short circuit.
What causes an external fan fault on Danfoss 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.
What causes inrush fault in Danfoss VLT HVAC Drive FC 102?
An inrush fault in Danfoss DC Drives is caused by too many power-ups occurring within a short time period. Let the unit cool to operating temperature.
