If the output current is close to 25% of the rated current, output phase loss may occur when . Auto-reset faults reset automatically if, after a preset time, the .2018. rooms to rent in gloucester The VFD responds to a fault by coasting to a stop & turning off output power to the motor. Six solutions: first is move drive closer to motor. ![]() It often also shows up eventually as single phasing or current unbalance. ![]() It is obvious on disassembly and will totally fail a surge test. The VFD may it may not show ground fault.Started doing some searching and reading, so I understand the principle of what this fault means but I'm having a hard time believing it's actually a phase loss, because several other VFDs are all running off the same three phases and this is the only drive that's faulting. Hi all, Client with a pretty much brand new AB Powerflex VFD starting throwing Fault 17: Input Phase Loss this afternoon. † Check for a power quality issue, take appropriate corrective actions. † PF Fault Code 3 or 4 † Check that the local disconnect is in the ON position. This is most likely due to a loss of 3-phase power. 24 = Power Loss (3-Phase) 25 = Under Voltage (3-Phase) † The ArmorStart's MCB lost communications with the VFD.
