Fig. 4-11:Relevant parameter settings for the example. The home position value is entered with PC07.

Following completion of the home position return:

The servo motor has travelled to the encoder home position which is also the machine’s physical home position. How- ever, this position corresponds to a value of 100mm in the ma- chine’s coordinate system.

Fig. 4-12:Values shown when the home position return has been completed correctly

The position value is calculated as follows:

X = PA05 ￿ PC07 in [mm]

In the above example with PA05 = 1 and PC07 = 1000 [10STM µm] this gives us:

X = 1000 ￿ 101 µm
