What to do if Danfoss DC Drives show mains phase loss?
If Danfoss DC Drives experience a mains phase loss, it means a phase is missing on the supply side, or the mains voltage imbalance is too high. You should check the supply voltage and supply currents to the frequency converter.
What to do if Danfoss DC Drives show DC over voltage?
To address a DC over voltage issue in Danfoss DC Drives, consider these steps: * Select Over Voltage Control function in 2-17 Over-voltage Control. * Connect a brake resistor. * Extend the ramp time. * Activate functions in 2-10 Brake Function. * Increase 14-26 Trip Delay at Inverter Fault. Selecting OVC function will extend the ramp times.
Why is there acoustic noise or vibration from my Danfoss Media Converter?
Acoustic noise or vibration could be due to resonances in the motor/fan system; check if the noise and/or vibration have been reduced to an acceptable limit. Also, turn off over-modulation in 14-03 Overmodulation. Try changing the switching pattern and frequency in parameter group 14-0*. Finally, increase Resonance Dampening in 1-64 Resonance Dampening.
Why won't my Danfoss Media Converter motor brake?
If the motor will not brake, it could be due to incorrect settings in the brake parameters or too short ramp-down times. Check parameter group 2-0* DC brake and 3-0* Reference limits.
Why does my Danfoss Media Converter motor run rough?
If the motor runs rough, it could be due to possible over-magnetization. Check the motor settings in parameter groups 1-2* Motor data, 1-3* Adv motor data, and 1-5* Load indep. setting.
Why is the Danfoss Media Converter motor speed unstable?
Unstable motor speed can be caused by incorrect parameter settings. Check the settings in parameter group 1-6* Analog I/O mode. For closed-loop operation, check settings in parameter group 20-0* Feedback.
Why is my Danfoss Media Converter motor not reaching maximum speed?
If the motor isn't reaching its maximum speed, it could be because the frequency limits are set incorrectly; program the correct limits. Also, the reference input signal might not be scaled correctly, so program the correct settings.
Why is the Danfoss Controller display dark and not functioning?
A dark or non-functioning display on your Danfoss Controller can result from several causes. It could be due to missing input power, so check the input power source. Also, check for missing or open fuses, or a tripped circuit breaker. Ensure there is power to the LCP and that the terminals are wired properly, addressing any shortcuts on the control voltage. Verify you're using the correct LCP (LCP 102, P/N 130B1107). Adjust the contrast by pressing [Status] + [?]/[?]. If the display is defective, replace the LCP or connection cable. For internal voltage supply faults, contact your supplier.
Why is my Danfoss Media Converter motor running in the wrong direction?
If the motor is running in the wrong direction, it could be due to a motor rotation limit, so program the correct settings. It may also be caused by an active reversing signal, so deactivate the reversing signal. Check the motor phase connection.
Why does my Danfoss Media Converter keep tripping the circuit breaker?
If the power fuses keep opening or the circuit breaker trips, it could be due to a phase to phase short, so eliminate any shorts detected. It may also be caused by motor overload, so perform a start-up 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. Also, check for loose connections and tighten them.
