The circularity (roundness) test
This tool helps improve and adjust the axis reversal peak, an effect that appears when
the axes reverse their moving direction. With this utility, a circle may be executed with
the axes and graphically show the result. This graphic shows the difference between
the actual (real) coordinate obtained from the feedback device and the theoretical
coordinate calculated at each point.
The same screen showing the graphics also shows the machine parameters that
affect the movement reversal. These parameters may be modified while running the
test, thus being possible to evaluate the response of the system to these changes
and optimize the adjustment on the go.
Selection of setup assistance
The different tools are accessed from the horizontal softkey menu.
Setup assistance may be accessed either using the user key if it has been set
accordingly or from the task window (by selecting the
Tuning option). The task window
may be accessed with key combination [CTRL]+[A].
