Hi, today my VS50 (18M control) came up with a F500 Over travel +X alarm after doing a tool change so I pressed the E stop & tried to move the spindle away from the tool changer manually, but it wouldn't move. I then turned the machine off a climbed up top & screwed the ball screw by hand to move it away (its now well away from the ATC position). While I was there I checked the limit switches & they are fine. I am still getting the over travel alarm on powering up & can not move any of the axis...I can not even remove the tool from the spindle.I read on the web that pressing PCAN on power-up will clear the over travel alarm & it does, but then I get D408.6 Escape X axis from ATC area & still can not move any of the axis.I then tried PCAN with the maintenance switch turned on & am now getting D408.3 Interlocked by ATC area, but can still not move anything.Any help would be greatly appreciated.
