The inverter is placed on the repair table, connected to 380 volts, the display panel displays F0001, and Fn cannot be reset. After the power is turned off, remove the power input and disassemble. It was found that the inverter part was stuck with a lot of oil. Clean the board of the module with the wash water. After the board is dried with hot air, it is tested. Inverter module fs100R12KS4, DC input and inverter three-phase output are not short-circuited, measuring the resistance of the six-way drive input 11 and 12 feet is abnormal. Carefully check the sot23 package Y4 (15 volts) with a drum kit to determine its damage; the resistance of the 3.3 ohm 1206 package becomes larger, and replace it with the same package of voltage regulator and resistor. Follow this lead to check the drive circuit, the diaphragm 4506, Y7 (20 volts), Z2 (5 volts), fzt651 damage, all replaced. Replace the module as well. After checking, the power is connected to 380 volts, the display panel displays F0001, and Fn cannot be reset.

Adjust the idea, since it is reported to F0001, then check the current detection circuit.

The current detection circuit of this machine is completed by three pieces of A786, and the A786 is normal. The peripheral inputs and outputs are also normal.

Had to find the power supply, driver board 540 volt input wiring, connected to the line power measurement A786 input measured Z2 voltage, the middle of the road Z2 no voltage, along the line to find the hole break, fill. The recovery circuit is energized normally.
