Hello, everyone.
I was wondering if anyone ever encountered noise coming from the servo motor on track 1? The noise starts as soon as the deadman switch is pressed on and continues while the robot drives up and down the rail. The moment you release the deadman switch the noise stops. It is a very unusual high pitch noise. It is not the same as on our other three robots. If you release the brake on track 1 and push the robot manually along the track, there is no noise.
Noise record: ABB IRB5350 track 1 noise
Here is our robot:
Thank you for your help.
