Have you properly defined the tool loaddata and the payload data using LoadID?

The robot works fine for 3 years, we have never changed tool or tool loaddata.

Was it initially set up at all? It is often times that I find robots where they did not set it up correctly from the beginning because they did not know how. As a Matter of fact, I have been to where the robot was so poorly setup and programmed, it was taught using tool0.

Has the robot been serviced? Lubrication changed when it should be?

This is loaddata of the robot,i’ve compare it with another similar robot,it’s the same.
No, the robot hasn’t been serviced this year due to covid issue.

Which axis is faulting? I would definitely drain the oil, examine it for contaminants, metal pieces. Also, if you can safely do so, release the brakes and push the joint around, see if it moves smoothly or has a crunchy spot.

It’s Axis 1, i’ve cheked oil level and quality, it looks fine .
Tomorrow I will try to move the joint manually and look for crunchy spot us you said.
Thnx for replying.

Hi again
So the robot only stops once in 3 days . And today I’ve released axis 1 brake and pushed the joint around. It was quite hard all around.
So my question is how can I be sure the problem is a faulty brake and not the gearbox or something else?!

Regarding Error 50055, you need to follow the instructions in the troubleshooting manual as listed below.
Description: Actual torque on joint arg too high. Might be caused by incorrect load data, too high acceleration, high external process forces, low temperature or hardware error.
Recommended actions: • Check load data. • Reduce acceleration or speed. • Check hardware.
When it comes to H/W error, the brake might be the reason. However, motor power cable issues were most common in my experience. So I recommend to replace the cable with new one.

@innebandy i’ve already changed the cable harness.

Please follow the instructions below.
Separate the motor unit from the gearbox. Connect a 24Vdc power to the motor brake. Switch on the power and rotate the motor shaft/pinion with your hand, then the shaft should turn smoothly without any resistance. On the other hand, the shaft must standstill while the power is off.
If this is your case, then the motor unit is okay.
