Hello,

Just got my Chinese 2.2kw water cooled spindle and VFD connected and put it through some tests. Thanks to all the available information out there everything went smooth and seemed to work well.

However, after successfully testing the unit for a while (20 mins), I stopped it and checked pd177-180 for error codes and each one showed an error code as follows:

pd177: ELu.n
pd178: ELu.d
pd179: ELu.A
pd180: EEr.n

From the manual I understand these to mean a Low Voltage fault during accel/decel/constant run as well as an External Interference fault during constant run.

The VFD is connected to 240V and spindle is connected via shielded 18 AWG wire.

Does anyone know what common causes for these faults would be? Also is there a way to clear the fault codes? I have not discovered a method yet.

Thanks,
Justin
