Jet ProMac FX-383V Operating Instructions Manual

FX-383V8. Troubleshooting the inverterPrior to operating all electronic parts, the following aspects should be taken into consideration firstNote: 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 disappearsfrom 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 programdetects an error, the machine will stop immediately and such error will be displayed on the inverter’s digital display. Followthe solutions to correct any errors. Close the electrical cabinet and connect machine to power supply.Code Error description SolutionO.C * The voltage inverter detects theoutput current exceeds the normalvalue.* Check if voltage of the motor matches with thatof the voltage inverter.* Check connection between the voltageinverter & the motor.* Check if the motor is overloaded.O.U * The voltage inverter of the motor isdetected with a D.C. high voltagelateral pressure value thatexceeds the acceptable range.* Check if the circuit input voltage matches withthat of the voltage inverter.* Frequent on/off and switches betweenclockwise and reverse directions result in self-protection from high D.C. high voltagelateral pressures.O.H * The touch pole of the voltageinverter of the motor indicatesoverheat.* Check if the circuit input voltage matches withthat of the voltage inverter.* Ensure the cooling device be free of anyforeign objects or dirt.O.L * The frequency converter detects theoutput exceeds 150% of normalstandards for 1 minute.* Check if the motor is overloaded. Ex:1. Cutters and tools are blunt?2. Spindle diameter, gear, speed andvolume of feeds proper?o.c.Ao.c.dd.c.n* Electric current is too large duringacceleration.* Electric current is too large duringdeceleration.* Electric current is too large duringoperation.* Check if the output connection of the motoradjuster 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 mistakenumbers continuously on the monitor, ask formore information from the after-sales servicecenter.
