I checked the diagnostic page, G022/122 don't response to the selection. And I found that Single block/rapid/etc switch which is located below the mode selector switch does change the G022/122 state, which means when i press and hold the rapid button, MDI mode will change to Auto. Holding rapid + single block will change the mode to Edit, and etc.
And I can't enter the PMC timer and counter data, either manually or using RS232. When I enter a 00001100 in N300, data is still kept at 00000000.
Now the machine can go off the emergency state and servo is ready, but none of the axis can move. Machine gives no alarm at all.
I begin to suspect that the parameter backup is not the original backup of this machine. But will any parameter cause the Mode selection problem?
