I have fanuc robot S420F-HT with RJ2. Controller .during robot teaching on my program, robot was stopped .
and at the moment when I select program menu, keys of teach pendent will be locked and 3 error RED LED on the axis controller board will lit.
And also when I push the edit menu or memory status, I can see these 2 error number on the teach pendent:
TPIF-017 WARN Memory read failed
MEMO-103 WARN Check sum error occurred
For this I have pressed and hold the SHIFT and RESET keys and While still pressing the SHIFT and RESET keys, I turned robot controller on but error is not cleared !!!!!
Fortunately I can jog the robot and also I can calibrate it. I guess problem is for the memory of robot !!!!!!!!!
According the fanuc documentation if I Press and hold the PREV and NEXT keys on the teach pendant, and then press the ON button.
The boot monitor prompt, BMON>, is displayed. But I couldn’t.
Does anybody has aide and help me? Why I couldn’t see boot menu?
