Fanuc J2 and J3 values are different

#1
Hello, 

We have Fanuc M-900iB/360 on the floor and I am trying to create an offline simulation for it. I cannot reach one of the position due to J2 hitting its limit in simulation but I can reach it in reality. I tried to modify J2 limits but I couldn't. Joints I am trying to reach are -94.916, -59.457, -2.508, 104.866, -4.913 and -79.986. But simulation robot has limit of -44. How do I change that? Thank you.

Please try using the updated robot.

Kindly let us know if this worked for you.

Hi,

I am having issue with this M-900iB/360 model again. It does not match the reality of the robot. Our cell configuration require robot to be operated at extreme reach position for J2 and J3 in linear motion. I can move robot in world base Y direction on the floor but simulation I cannot move through these positions. Please see the attached images. I was able to move it by going to parameters, options in robot kinematics then use iterative inverse kinematics. I am just not sure how accurate this resemble to reality. 

Thanks,

Manan Trivedi

This robot model is working fine. Only issue I have observed is when I try to move the robot using the scroller wheel in Robot Base, I need to ensure I select the robot base frame as my active frame. It does not seem to like another frame as an active frame eventhough I am moving in Robot Base.

Thank you.

Thank you for bringing this to our attention. We will update the robot in our library shortly.
