33.24 Step Loss Test

The stiffness of the 3 axes can be tested in this menu.

When you are in the service menu, sequentially select the following

menu items with the arrow keys and the “OK” key:

- Test Functions

- Step Loss Test

The “ Step Loss Test ” menu appears.

This menu item serves for testing the mechanical sluggishness in the

machine. An axis is too sluggish when, with an empty run rpm of 2800,

the step losses exceed 1 step.

–

To start the test program press the “RST” key.

–

The starting rpm is 2800 min

-1

. All axes are moved a defined

distance in the “+” and “-”- directions, then referenced. Thereby

any possibly occurring step losses are established and displayed.

–

The idle rpm is then increased by 100 min

-1

until more than 5 step

losses have occurred on all 3 axes.

The test is then ended automatically.
