'''This does not apply to the V axis on a ZX5 which works in reverse i.e the axis is 'home' when the switch is not made.''' * In the drives tab on the service screen in WinMulti press 'Home' on the first axis. Keep a close eye on the direction of travel. If it is travelling away from the datum switch then it is moving in the wrong direction and needs to be stopped quickly. * Repeat for the rest of the axes in turn. Wait for one axis to finish before starting another one. * Make a note of which axes are homing in the wrong direction. These will need to be changed in the TwinCAT project. need to be changed in the TwinCAT project. +

* Close WinMulti and open the TwinCAT project.
* In the Motion tab in the TwinCAT project navigate to the Axes tab (1).
* Refer to the list you made earlier of the axes that are datuming in the wrong direction. Select the first axis that was wrong and navigate to the 'Enc' tab (2).
* Open the Parameters tab (3) and scroll down to 'Homing' (4)
* There are two parameters in there called 'Invert Direction for Calibration Cam Search' and 'Invert Direction for Sync Inputs Search'
* In order to change the homing direction 'Invert Direction for Calibration Cam Search' needs to be swapped from True to False or from False to True depending on what it is already on.
* In order to change it, use the drop down menu in the 'Offline value' column. When changed, the 'Online value' will change and turn red. Click download to turn it blue again.
* Whatever 'Invert Direction for Calibration Cam Search' is, 'Invert Direction for Sync Inputs Search' needs to be the opposite. Otherwise, the axis will continue to move in the same direction once the switch is made.

This is a more accurate method of datuming, meaning that the datum will be more consistent as when set to other reference methods, the datum can change by up to 10mm depending on the physical position of the datum switch. *To change this, stay in the same 'Parameters' tab in the 'Homing' section and follow the same process as above, this time changing the 'Reference mode' (1) to 'Software Sync'. *Repeat for all the above axes *Save all' and 'Activate configuration'. *Reopen WinMulti and test the homing directions again to double check. he homing directions again to double check. +

Changes in gearboxes or motors will affect the scaling factor# Simply mark the axis, move it a known distance and ensure it is correct.
