What does Motor ETR over mean on Danfoss Media Converter?
If your Danfoss Media Converter displays a Motor ETR over error, which indicates that the motor is overloaded by more than nominal current for too long, make sure that the motor par. 1-24 is set correctly.
What to do if there is a ground fault in Danfoss Media Converter?
If there is a discharge from the output phases to ground in your Danfoss Media Converter, turn off the adjustable frequency drive and remove the ground fault.
What to do if Danfoss Media Converter shows overcurrent?
If the inverter peak current limit is exceeded in your Danfoss Media Converter, turn off the adjustable frequency drive and check if the motor shaft can be turned.
How to fix drive overtemperature in Danfoss Media Converter?
If your Danfoss Media Converter is showing a drive overtemperature error, which could be due to a high ambient temperature or a motor cable that is too long, wait until the temperature of the heatsink is below 158°F [70°C].
How to solve brake resistor power limit on Danfoss Media Converter?
If your Danfoss Media Converter indicates a brake resistor power limit issue, which means the power transmitted to the brake resistor is too high, check the brake resistor and parameters.
How to solve no motor issue on Danfoss Media Converter?
Connect a motor to the output of the adjustable frequency drive of your Danfoss Media Converter.
Why do the power fuses open or the circuit breaker trip on my Danfoss Controller?
If the power fuses are open or the circuit breaker trips, it could be due to a phase to phase short; eliminate any shorts detected. Another cause could be motor overload; perform a startup test and verify the motor current is within specifications. If the motor current exceeds the nameplate full load current, the motor may only run with a reduced load. Review the specifications for the application. Loose connections can also cause this, so tighten any loose connections.
Why is the motor speed unstable when using a Danfoss Controller?
If the motor speed is unstable, it may be due to incorrect parameter settings. Check the settings in parameter group 1-6* Analog I/O mode. For closed-loop operation, check the settings in parameter group 20-0* Feedback.
What to do if the motor is not running with my Danfoss Controller?
If the motor is not running, ensure the motor is connected and check the service switch. If you're using a 24 V DC option card, apply mains power to run the unit. If the LCP is stopped, press [Auto On] or [Hand On] (depending on your operation mode) to start the motor. Apply a valid start signal if there is a missing start signal (Standby). If the motor coast signal is active, apply 24 V on terminal 27 or program this terminal to No operation. If the reference signal source is wrong, program the correct settings and check the wiring, scaling of terminals, and reference signal.
