    Hi, I am new to this forum and pretty new to programming fanuc robots. I do have one program that is working in production under my belt. The company I work for recently bought a used M-20iA with a R-30iB controller. The robot was tested and worked before it was shipped to our facility. However, not upon start up the robot faults out and gives the error messages:

    SPOT-474 NM&OUT24v shorted after MCC

    SPOT-476 Fix Pwr short & then cycle

    I am wondering if a wire was vibrated loose during the shipment, however I have not been able to find anything in the cabinet. It looks like all of the boards are lighting up and working fine. I have been unable to find any documentation on these particular SPOT errors.

    Has anyone experience this error and knows how to fix it? Or does anyone have resources that may shed light on the situation? Thanks!

    Looks like 24V output fuse is blown. Check all fuses FS1 FS2 FS3 fuse. You can use multimeter , Check with continuity function.

    I hope it will sort out

    Thank you for the help. However, I just checked all of the fuses on the servo amplifier as well as on the e-stop circuit and they were all good. Any other ideas?

    jnelson I'm currently facing your same issue and keep hitting dead ends when looking for information.

    Did you ever resolve this?
