Code Error Description Solution
O.C.
* The voltage inverter detects
that the output current exceeds
the normal value.
* Check if motor voltage matches that
of the voltage inverter.
* Check connection between the
motor and the voltage inverter.
* Check if the motor is overloaded.
O.U.
* The voltage inverter of the
motor is detected with a D.C.
high voltage lateral pressure
value that exceeds the
acceptable range. * Check if the circuit input voltage
matches that of the voltage inverter.
* Frequent on/off and forward/reverse
directions result in high voltage self-
protection.
O.H.
* The touch pole cooling device
of the motor voltage inverter
indicates an overheat condition.
* Check if the circuit input voltage
matches that of the voltage inverter.
* Make sure the cooling device is free
from dirt and foreign objects.
O.L.
* The frequency converter
detected an output exceeding
150% above normal for 1
minute. * Check if the motor is overloaded.
Tooling may be dull. Check for proper
sized tooling, gear speed, and feed
rate.
o.c.A
o.c.d
o.c.n
* Electric current is too large
during acceleration.
* Electric current is too large
during deceleration.
* Electric current is too large
during normal operation.
* Check if the output connection of the
motor adjuster is insulated improperly.
G.F.F
* Grounding or safety wire
issues. * Check if grounding is adequate.
* Replace safety fuses.
C.F1~3 or others
* Internal EEPROM cannot be
read or programmed.
* Current sensor error.
* U-phase error.
* W-phase error
* Replace Variable Frequency Drive
