Hello, please check the manual chapter 3.4.4 Adjust your settings. 3.4.4 Target range The target range of a positioning operation of rapid traverse/creep speed positioning is located symmetrically around the target position. The target range is used to monitor a positioning operation’s positioning accuracy. If the axis does not reach the target range after the monitoring time has expired, an error is output on the "2SpeedPositioning” function block. In the parameter data block, the target range is defined by the "targetRange” tag. Proceed as follows to determine the correct setting of the tag: 1. First, select a large value for the target range to avoid an error message when positioning the axis. 2. Then determine the switchover and switch-off difference of the axis very accurately to enable a very accurate positioning operation to the target position. 3. Now perform different positioning operations with the axis and check by how much the results deviate from the target position. The maximum of ‘less than/greater than target position’ defines the symmetrical target range.
