Stone engraving machine fault code: DL output short circuit check whether the motor and cable line are short-circuited, OL1OL2 load is too large, the motor is blocked, the blockage phenomenon is eliminated, and the load is reduced.
. LU undervoltage input voltage abnormality check input power supply, OH overheating load is too large, cooling fan is damaged, reduce load, replace fan (Note: When the inverter displays DL, the reset button is invalid, please power off and restart the inverter to eliminate the fault), TALENT series inverter is common Fault and handling (2.2 kW)
Fault code: EOCD output short circuit Check whether the motor and cable are short-circuited, EOU input voltage is too high Check voltage, EOCN output circuit phase-to-phase short circuit or short circuit to ground check wiring and motor, ELU has large starting current load in the same power system The wiring avoids the load, and the TL external interference separates the control line from the strong power.
