Fanuc RB how to set a slow start after RB's stop mid program.

  • Hello,

    Fanuc 420iW 175 Rbs, R J2 controllers

    Fanuc RB spot weld cell, using pneumatic spot guns

    I'm wondering if it is possible to set up my Robots to have a slow start after being stopped mid task. Whether they stopped due to an error or due to tech intervention, I want the first step after restarting to be a slow start just in case Robots came to a hard stop and I do not want to have the Robots start at 100% instantly at restart. I've set "Production Resume speed" to 50% but that just makes the Robots complete their current cycle at 50% speed, and then will run at 100% speed on the next cycle.

    I know Nachi, Kawasaki and other robots have this feature and would like to implement this into the Fanuc Robots if its possible.

    I should add that I have zero Fanuc Robot training. I just started a new job and I am the one responsible for this Fanuc RB Weld cell. Everything I know and have accomplished so far is just from playing around with the robots and reading online Forums/manuals

    Changed the title of the thread from “Fanuc RB how to set a slow start after Rs stop mid program.” to “Fanuc RB how to set a slow start after RB's stop mid program.”.
  • Does that era of controller have background logic? I can think of an easy way to do it with that, but we will have to confirm.

    Check your setup menu and look for BG Logic under the TYPE.
