I am just asking for my brother who is dealing with this particular problem.

it is working fine for 8 years...now it seem to have a problem with reversing from 180 back to 0 and it always stops at about 85 with higher speed like 100% if running at 50% or 75% it is fine...and forwarding from 0 to 180 is no problem as well...

- Has replace with new program
- Has replace with rebuilt motor and amplifier

what else could it be? any helps appreciate it.

You need to identify which axis is giving this bad behavior. Also, 8 years is a lot of time for a robot.

Robot is 6 axis...it is the main base axis (Y), and I am sure it is nothing to do with aged of robot...this is only happens on the reverse (counter clockwise) with higher speed...and clockwise is running fine with any speed...

It was just the gearbox...all running smooth now...
