Error description
Solution
O.C
* The voltage inverter detects the
output current exceeds the normal
value.
* Check if voltage of the motor matches with that of
the voltage inverter.
* Check connection between the voltage inverter &
the motor.
* 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 with that
of the voltage inverter.
* Frequent on/off and switches between clockwise
and reverse directions result in self-protection
from high D.C. high voltage lateral pressures.
O.H
* The touch pole of the voltage inverter
of the motor indicates overheat.
* Check if the circuit input voltage matches with that
of the voltage inverter.
* Ensure the cooling device be free of any foreign
objects or dirt.
O.L
* The frequency converter detects the
output exceeds 150% of normal
standards for 1 minute.
* Check if the motor is overloaded.
Ex:
1. Cutters and tools are blunt?
2. Spindle diameter, gear, speed and volume of feeds
proper?
o.c.A
o.c.d
d.c.n
* Electric current is too large during
acceleration.
* Electric current is too large during
deceleration.
Electric current is too large during
operation.
* Check if the output connection of the motor
adjuster is insulated improperly.
C.F.F
* Grounding or safety wire mistakes
* Check if grounding is proper.
* Replace safety fuses.
* When the diode shows the same mistake numbers
continuously on the monitor, ask for more
information from the after-sales service center.
C.F 1~3 or
others
Abnormal detection inside the frequency
converter
* Place the machine outside the circuit.
* Restart the machine.
* When the diode shows the same mistake numbers
continuously on the monitor, ask for more
information from the after-sales service center.
