Over-current during constant
speed
(oCn) {08}
Check for possible poor insulation at the output wires
Check for possible motor stall
Replace the drive with the next higher power model.
Over-current during
acceleration
(oCA) {09}
Check for possible poor insulation at the output wires

on again ,If fault code is still displayed please
return to the factory.
IGBT overheat
(oH1) {17}
IGBT temperature exceeds
protection level
Check the cooling fan and clean it
Ensure that the ambient temperature falls within
the specified
Remove any foreign objects on the heat sinks and
check for possible dirty heat sink fins.
Make sure that the ventilation path is not
obstructed.
Provide enough spacing for adequate ventilation.
Environment overheat
(oH2) {18}
