Error
Code
Input Phase Loss
A function that detects phase loss in the input AC source. Detection is
performed using the fluctuation in the main circuit's DC voltage. Also, in
the case of degradation of main capacitors it could be occurred.
PF
Ground Fault
When ground fault is detected on running condition, the output is cut
off.
GF
Fan Fault
The Fan fault is indicated when the fan is not rotated
FF
OVS control fail
The OVS output frequency is higher than maximum OVS output
frequency during the setting time when the OVS function is enabled
ovSF
External Event
When the external equipment or unit has an error, the VFD receives the
corresponding signal and cuts off the output.
EE1~EE5
Safety input trip
When the terminal of safety has opened
SAFE
System Overload
Detection Fault
The output current of the drive is greater than the detection level set for
this feature when it enabled
oLdt
System Underload
Detection Fault
The output current of the drive is less than the detection level set for this
feature when it enabled
uLdt
Braking Resistor
Overload Trip
When DBR exceeds the duty cycle of the braking resistor this fault will
occur. The circuit is designed to calculate and protect the braking
resistor from thermally overheating
