Product Details
Siemens S120 Driver IGBT Module Report F30021 Grounding RepairThe possibility of grounding faults in Siemens S120 power cables and motors, as well as faults in frequency converters. Suggest checking the power cable connection and motor insulation status, 828D system alarm 230021 power unit grounding, Siemens 802DSL CNC system alarm grounding fault code 230021, Siemens 840D CNC detection motor shaft alarm 230021 maintenance, overcurrent, cable grounding, motor grounding, drive grounding, RDY red light on, no output from frequency converter, unstable operation of output phase loss motor.
Check the appearance of the power cable for damage, aging insulation layer, or water immersion, with a focus on investigating the risk of short circuit between the U/V/W phase line and the grounding wire.
Insulation testing of motors and cables
Use a multimeter to measure the output signal of the driver (such as whether the 2.2V output of the 786J module is normal). If it is abnormal, replace the IGBT module.
Check the resistance value of the current detection resistor (such as the resistance value of pins 2 and 3 of 786J should be around 78 Ω). If the deviation is too large, it needs to be replaced.
Trigger board and power unit:
Check if the trigger board power supply voltage (such as 24V) is stable and if the trigger pulse waveform is normal.
Test whether the IGBT module is broken down, observe the waveform of the output terminal to ground voltage with an oscilloscope, and exclude the grounding of internal power devices
