Our Bridgeport Hardinge machine keeps flashing up "Error 291 PLC-Modul 9091" and "Error 293 PLC-Modul 9093" on the controller. Otherwise working ok.
Have tried asking our normal CNC maintainance guy what they mean and what the to-do is but he hasn't encountered them before so asking here in case anyone here knows what my problem is or might be?
The machine is a Bridgeport Hardinge Heidenhein iTNC530
