Compensation:
Enter the backlash in MP710.x.
In MP709.x, enter the time in which the distance to be compensated should
be traversed.
The value of the backlash is added to the position value at every reversal of
direction (even if it results from a nonlinear axis-error compensation, for
example) and corrected by the position controller. The value of the k
V
factor
therefore influences the settling time for backlash compensation.
In special cases, such as long ball screws with narrow diameters, additional
tension in the system can lead to undesirable dynamic side effects. In order to
compensate for this tension at the reversal point, enter in MP709.x the time
in which the distance to be compensated (from MP710.x) should be traversed.
