Fanuc CRX-25iA Slow Motion

krgaurav22 · August 26, 2023 at 1:56 AM

We have a new Fanuc CRX-25iA robot and it moves really slow in linear motion. My program looks like following:

L P[1] 250mm/sec FINE. ;

LP[2] 250mm/sec FINE ;

.....

....

The robot stops at each point for at least 2 seconds. This robot does not have R663 Constant Path option. We have a CRX-10iA/L and that one has this option. And it moves with normal speed.

Do I need to buy this Constant Path option or is the issue something else?

Check that your override and program override are both at 100%.

I have the override set to 80% and I see that teaching pendant shows 80% when the program is running.

Also, I have another program with CNT100 for each move and the robot moves better in that case. Although, it is not as fast compared to other robot CRX-10iA/L we have.

Did you figure out what was the reason for the Crx-25ia running so slow ?

Fine and CNT are your point termination. With fine it gets to complete stop, with CNT you can control how close the arc movement will be to your point. So normally it should not pause between points with FINE. Are CRX 10 running in collaborative or fast mode? If I remember right in collaborative they run @1000mm/sec max.

To me seems you robot settings needs confirmed.

Maybe a problem of configuration try this :

Go under CTRL Start (FCTN -> 8 Cycle Power -> Option -> CTRL)

MENU -> MAIntenance -> F4 :MANUAL

Set motion option to Cycle time priority.

Then FCTN -> Start cold.

WARGING :

This may change a little bit the path since it change the acceleration of the robot.
