Gentlemen,
We are recovering from a failure on a Seiken windingmachine.
This particular machine has three Fanuc PowerMatecontrollers [A028-0211-B501] attached to 10 different Fanuc amplifiers[A068-6093-H101]. These amplifiers drive Beta series servos. PowerMates 1 & 2 were sent out to be rebuilt. The OEM parameters were not available, so we have re-engineered the parameter settings. Myself and another engineer are confident these parameters are correct.
We get no faults onthe handheld programming unit. Controller #3 functions, and its amplifier, [it only has one] has the “Ready” LED illuminated. The two controllers that we have had to reprogram are connected to the remaining 9 amplifiers and none of theseamplifiers have the “Ready” LED illuminated.
All three PowerMates have the EN LED illuminated. The two nonfunctioning PowerMates also have the S0 LED illuminated.
The system is not in Estop mode.
Any advice is appreciated.
Best Regards,
Joe
