Special maintenance operations must be carried out by skilled personnel. However, we advise contacting dealer
and/or importer the term special maintenance also covers the resetting of protection and safety equipment and
devices.

Prior to operating all electronic parts, the following aspects should be taken into consideration first
Note : Only eligible and qualified personnel can make electronic adjustments.
1. Disconnect machine from power supply.
2. Electronic parts are extremely sensitive, do not use hands or metal tools to remove or install such parts.
3. As remaining voltage still exists in the capacitor even after the electric current has been cut off, wait until the
light disappears from the lighted display completely before proceeding with any work to prevent any accidents
or hazards from occurring.
4. Pay close attention to the electronic circuit board so that they are free from any defects.
5. Never connect the alternating current directly to the output connector (U/V/W) of the speed adjuster. The
electronic self-diagnosis program can notify you of situations like motor overloading and too low or too
high voltage, etc. When the program detects an error, the machine will stop immediately and such error will
be displayed on the inverter’s digital display. Follow the solutions to correct any errors. Close the electrical
cabinet and connect machine to power supply.

Code 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.
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 connection between the voltage inverter & the
motor.
* Check if the motor is overloaded.* Check if the circuit
input voltage matches with that of the voltage inverter.
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/quills are blunt? 2. Quill 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.
