6-15 Backlash Correction

Overview

Automatic or Manual;

Method:

Command Area designation, CX-

Motion

A backlash is a sudden backward movement of a driving axis that may be
caused due to mechanical looseness as shown in the following illustration.

The positioning of a machine cannot be performed precisely if there is back-
lash.

As shown in the following illustration, for example, the position of a machine
moved by 100 mm in the forward direction is different from that of the same
machine moved by 100 mm in the reverse direction if there is a 1-mm back-
lash, even though there is no difference in position between the driving axes.

Backlash correction is a function for pre-registering the backlash space within
a range of 0 to 10,000 pulses to minimize the positioning errors of machines
moving in the forward or reverse direction to the same position, as shown in
the following illustration. The setting is made with the backlash correction
value in the servo parameters.
