relocation error

With a displacement of ~0.7 mm, an error accumulates. We noticed that when there is a program with such a movement, after 3 minutes an error of 2 mm accumulates. With normal movements, there is no such problem. The mechanical part of the machine is in good working order. Tom, what could be the problem?

Hi Ivan,
What do you mean by displacement?
What type of machine do you have?
Do you have encoders?
If the physical position changes but the encoder Position does not then there is a problem with the encoder measurement. Either with the encoder itself, or noise in the encoder signals, or in the controller.
I can't think of any significance to 0.7mm. Maybe that is a bad spot on the encoder?
