We are having, here in at our plant of Brazil, frequent failures by IOC and Overspeed (mainly on 10/10/2016 and 05/10/2017) in SIEMENS / ROBICON PHGH180 / GEN3E Frequency Converter. The Motor voltage = 6600 V and Full load current = 294.8 A We have not come to a conclusion about the cause. We change the system I / O and the equipment returns the operation but the premature failure is doubtful if it is the real cause of the problem is something with respect to noise, grounding and the System I / O board. The following are the logs of the last fault and the register of pick zero sequencie voltage.
