Linear jog not working as expected

Hi everyone.

I have a IRB120 mounted normally (not upside-down) and I want to use the linear jog feature with the teach pendant. The problem is: while jogging in Z axis, the end of arm moves drawing a diagonal line with respect to the vertical, instead of drawing a line parallel to the vertical. The same odd movements are seen while jogging in X and Y axes. Could it be a bad setting in the robot configuration?, am I missing something while using the jogging feature?

The quaternion values configured in the Motion topic are: q1= 1, q2= 0, q3= 0, q4= 0

Which seems to be a good configuration for a normally-mounted robot.

Thank you in advance for your help.

Regards.

Hi,

Check that the coordinate system in the jogging window is on base or world not in tool or work object.
