10. Set drive enable: The system returns the message "Start enabled." Click "Start" to
position the axis to the default incremental dimension. The "Distance to go" and "Position
reached -- Stop" displays indicate the positioning accuracy. You can improve positioning
accuracy by reducing or increasing the switchover and switch-off differences.
11. You also obtain the "Position reached -- Stop" message by increasing the target range.
Adjust those parameters until you receive the "Position reached -- Stop" message and the
actual positioning value is close enough to being equal to the incremental dimension.
Note down the values you have thus determined for the positive switchover / switch-off
differences.
12. Select a negative incremental dimension to determine the negative switchover and
switch-off differences.
13. Select "Change Parameters For > Drive", open the drive parameter view, then enter the
determined values at the relevant parameters.
14. Click "File > Save" to save your settings, then exit the configuration software by clicking
"File > Exit".
15. Save your configuration to your project with "Station > Save and compile".
16. When the CPU is in STOP mode, choose "PLC > Download to module..." to download the
configuration.
