Hi guys I have many Older Fanuc 420F Robots with RH Controls running through out the shop, But just ran across this new issue with 2 of the same robots I just installed, I hooked them up, mastered them, taught the whole cell everything works the only problem I'm having is:
Every time I lock out the robot cell, and come out and unlock, turn servos back on hit reset (Servo Disconnect Box) I have to re calibrate the robot every time.. We have 16 other robots that work fine, (Unlock the cell turn servos back on reset) No Problems I've been searching for answers and cant seem to find any.. just wondering if any of you Fanuc Experts can guide me in right direction as to why i have to recalibrate every time?
I have Jumped EMG IN1 and EMG INC and EMG IN2, also another Jumper on FN1 and FN2, (FOR TESTING ONLY)
so the only safety left is the Servo 3phase Disconnect Power Wires that go threw a rotary switch
Thanks for any info
Sam
