5.1. Method of Progressing an Investigation of the Causes of Problems

 

When an abnormality occurs during the operation of the positioner, and it is not attributable to an abnormality with the controller, it will be a problem because of damages to the mechanical parts. To solve the problem quickly and easily, it is necessary first to identify the phenomenon correctly and determine which part is defective.

 

(1)    First step: Which axis has an abnormality?

 

First of all, check which axis that shows the abnormal phenomenon. When it is difficult to make a judgment because the abnormality does not appear during the operation, it is required to carry out an investigation as follows.

 

l  Is there any part generating an abnormal sound?

l  Is there any part generating an abnormal heat?

l  Is there any part with a gap?

 

(2)    Second step: Are there any damaged parts?

If an axis is determined to have an abnormality, it is required to investigate which part is causing the abnormality. There can be several causes of one phenomenon.

 

(3)    Third step: Handling of defective parts

Parts that are determined to be defective should be handled according to the methods described in Section 5.2 Methods for Investigating and Handling Individual Parts. Please contact our service department for items that your company cannot handle.
