I have been getting the E7120 error code in my TA1400 Panasonic Welding Robot. I was told by a technician to replace the servo motor, so I did and the error hasn't changed. The robot won't move and any time I try with the teach pendant, it will throw this error.
Did you get this problem figured out? We're running into an E7120 error on our machine that has had us baffled for months.
