Chapter 12 Checking and Troubleshooting 12-5 E-Thermal Type Cause of Trouble Solution Out Phase Open In Phase Open Inverter OLT Over Heat Over Current2 NTC Open FAN Trip IP54 FAN Trip � The motor is overheated. � The load of the inverter is bigger than its rated load. � The electronic thermal level is set too low. � The inverter has operated for a long time at a low speed. � Contact trouble of the electronic contactor of the output side. � Bad distribution of output � Contact trouble of the electronic contactor of the input side � Bad distribution of input � The DC condenser of the inverter needs replacing. � The load of the inverter is bigger than it’s the inverter rating. � Torque boost is too high. � There is a problem with the cooling system. � The inverter has been used longer than the replacement cycle of the cooling fan. � The surrounding temperature is too high. � Earth of the output cord of the inverter � There is a problem with the inverter power switch(IGBT). � The surrounding temperature is out of the prescribed range. � There is a problem with the internal temperature sensor of the inverter. � There is foreign substance in the inverter vent where the fan is. � The cooling fan of the inverter needs replacing. � Internal fan connector is not connected. � Internal fan PCB board’s power connector is not connected. � Inverter cooling fan become to change period time. ☞ Reduce the load or frequency. ☞ Raise the capacity of the inverter. ☞ Set the electronic thermal level properly. ☞ Replace the motor for one that can separately supply power to the cooling fan. ☞ Check the electronic contactor of the output side of the inverter. ☞ Check the output distribution. ☞ Check the electronic contactor of the input side of the inverter. ☞ Check the input distribution. ☞ You should replace the DC condenser of the inverter. Get customer service from an agency. ☞ Raise the capacity of the inverter and motor. ☞ Reduce the torque boost amount. ☞ Check whether there is any foreign substance in the vent, air duct or outlet. ☞ Replace the inverter cooling fan. ☞ Keep the temperature around the inverter below 50°C. ☞ Check the output terminal distribution of the inverter. ☞ Inverter operation is impossible. Contact a near service provider. ☞ Keep the temperature around the inverter below the prescribed degree. ☞ Contact a near service provider. ☞ Check the vent or air outlet. ☞ Replace the cooling fan of the inverter. ☞Connect internal Fan connector. ☞Internal fan PCB board’s power connector is connected. ☞Inverter cooling fan have to changed.
12.1.4 Replacement of cooling fan Chapter 12 Checking and Troubleshooting 1) Replacement steps of the product below 7.5kW Push the bracket on the bottom to the arrow direction and pull it forward. Disconnect the connector of the fan, then you can replace the fan. 2) Replacement steps of product of 11~15kW 200V/400V, 18.5~22 kW 400V Release the volts under the In-Out put terminals and disconnect the connector of the fan, then you can replace the fan. 12-6
