I believe you can hold down the "P" and "CAN" buttons while powering up the machine. This should temporarily ignore the overtravel alarms and allow you to move (HANDLE or JOG) the offending axis away from it's limit. I haven't done this myself in a loooooong time, so "caveat emptor".
Mankoo43 says he has + AND - O.T. alarms in both axes. I don't believe you can move an axis with both + and - O.T. alarms.
506 & 507 are HARD overtravel and P CAN will not work on these alarms. You lost your 24V that feed these switches. You will need your electrical prints to see where you lost it.
P-Can is for Soft over travel.
Alarm 506 = Over Travel: +n (Hardware)
Alarm 507 = Over Travel: -n (Hardware)
Content: Exceeded the n-th axis hardware OT. Check 24v to overtravel limit switch. Move off of hard limit switch. The signal is active-low, requiring 24v applied to deactivate, so a loss of 24v or tripping of the switch causes the alarm.
Troubleshooting:
Check 24v to overtravel limit switch. Move off of hard limit switch.Check function of switch.
Specific to your case: Press and hold the Blue Alarm RESET button, if Machine Ready is allowed and hydraulics are able while blue button is pressed, then the problem is in the switch/switches. (the blue button only provides a path around the switches and over-torque clutch inputs...it uses the same 24v. If blue button does nothing, check the voltage supplied to switches as well as the input they arer being read at.

If given a serial number, I can describe where to check, via the electrical print.
