5. Fault Diagnostic Methods
5-5
Displayed Code Description of Failure Solutions
The output current is higher than the
withstand current of the Hybrid
servo drive.
Check if the motor for overload.
Increase the output capacity of the Hybrid servo drive.
Motor overload
Change the product condition
DC side fuse (FUSE) burns for
models of 30HP and below.
Check if the fuse of the transistor module is burning.
Check the load side for any short circuit
Memory write error.
Memory read error.
Press the RESET button to reset the parameters to
factory default settings.
If this method does not work, return to factory for
repair.
Error of the sum of the three-phase
output current is detected
Error U-phase current is detected.
Error V-phase current is detected.
Error W-phase current is detected.
After restart the power supply, if the error still exists,
return to factory for repair.
When the external EF terminals
close, the Hybrid servo drive stops
output.
After clearing the cause of the error, press the
“RESET” button.
When the external EMG terminals
close, the Hybrid servo drive stops
output.
After clearing the cause of the error, press the
“RESET” button.
The Hybrid servo drive detects
errors from the braking transistor.
After press the RESET button, if the message bF still
exists, please return to factory for repair.
OH1 hardware circuit error
Return to factory for repair.
OH2 hardware circuit error
Return to factory for repair.
cc protection hardware circuit error
oc protection hardware circuit error
ov protection hardware circuit error
GFF protection hardware circuit
error
After restart the power supply, if the error still exists,
return to factory for repair.
