Hi,
We have been receiving this major alarm on 2 of our NX100 cells. More frequently on one specific cell. We have tried various methods to solve the issue such as swapping teach pendants, pendant cables, swapping the I/O circuit board, checking connections to other various circuit boards, but to no avail. It seems that cycling the power is the only way to get rid of the issue and while it works some of the time, other times it has no effect. If anyone has any other options we can try that would be greatly appreciated.
Thanks.
*Now receiving External axes overrun alarm in addition to the safe circuit signal.
