Hi gang, I have an e/r module last part 1BA02-0CA0 I'm getting intermittent UzK faults. I can cycle the power and it will come up and run for a while. It's really a nuisance because the 840c take so long to reboot. Anyway, the machine is a Hyundai HIT 15 and is running on a phase converter. I know from when I used to do service and installation on these machines, we are not supposed to have more than 400 volts on the input power to the E/R module. I have 440vac. So my question is can what I'm seeing be a regen fault from when the spindle or axis motors stop after a rapid move. That is when I see it, I can say for sure if it is when it starts on stops yet. This ahs always been a problem since I have had the lathe, but it is becoming a problem that needs to be addressed. Thanks Paul Naylor ------------------------------------------------------------------------------------------ |

Please set S1 switch on infeed module to ON position since your case supply voltage is 440 V AC. For more details, please refer attached sheet. |

Try to make correct S1 setting, if you still have trouble, You need to replace power supply module --I think it is 36/47 kw , I have lots of services cases same like yours. your PS module infeed function is good--so machine can running, but reg./feedback function is gone. when spindle running from hi speed to braking and stop--it will will trig DC link over-voltage- Siemens already discontinued your product. I suggest you search online to get some good conditioned or refurbished PS It can be --0CA0 or 0CA1, If you need more information let me know or PM me
