YASKAWA inverter maintenance
Model: CIMR-G7-75
Failure phenomenon: the main circuit of the cable fault
Failure analysis: inverter G7-75KW customer reaction that the inverter is used for crane unloading, in the use of sudden alarm. The company‘s engineers measurement module to damage a group of W phase. The driving part also see the obvious traces of burning. Main circuit two 350A insurance to burn. Remove module test board CPU detection alarm CPF00, detection for the motherboard connection error alarm. Repair W driver for the motherboard driver after the test drive are normal. Description CPU motherboard problem. Re detection of CPU motherboard made a significant power supply and detection problems. Replace the detection of IC, LM358 and 3315 after the display is normal. Re install the module and insurance test everything is normal.
