Why Danfoss VLT Micro Drive FC 51 display a live zero error?
A live zero error in Danfoss DC Drives occurs when the signal on terminal 53 or 60 is less than 50% of the value set in parameter 6-10 Terminal 53 Low Voltage, parameter 6-12 Terminal 53 Low Current, or parameter 6-22 Terminal 54 Low Current.
What to do if Danfoss VLT Micro Drive FC 51 DC Drives show mains phase loss?
If your Danfoss DC Drives system reports a mains phase loss, it's likely due to a missing phase on the supply side or a voltage imbalance that is too high. To resolve this, check the supply voltage to ensure it is within the acceptable range.
Why Danfoss VLT Micro Drive FC 51 show short circuit?
A short circuit in your Danfoss DC Drives system is caused by a short circuit either in the motor or on the motor terminals.
What causes live zero error in Danfoss VLT Micro Drive FC 51?
A live zero error in Danfoss DC Drives occurs when the signal on terminal 53 or 60 is less than 50% of the value set in parameter 6-10 Terminal 53 Low Voltage, parameter 6-12 Terminal 53 Low Current, or parameter 6-22 Terminal 54 Low Current.
Why Danfoss DC Drives report brake resistor short-circuited?
A brake resistor short-circuited error in Danfoss DC Drives means that the brake resistor is short-circuited, which disconnects the brake function.
Why Danfoss VLT Micro Drive FC 51 DC Drives report brake chopper short-circuited?
A brake chopper short-circuited error in Danfoss DC Drives means that the brake transistor is short-circuited, thus the brake function is disconnected.
What causes control word time-out in Danfoss VLT Micro Drive FC 51?
A control word time-out error in Danfoss DC Drives indicates that there is no communication to the frequency converter.
