3.5.3.2 Sequential Logic Control of Positioning and Homing
Concerning the gantry control method of ASDA-A2, the control logic of positioning and homing
has to be completed by the host controller. The control sequence of a host controller and how it
works is explained in previous sections. The detailed control flow chart is hereby presented.
Users can decide whether to use either the positioning point or Z pulse as the homing origin.
a. Two axes symmetrically return to positioning point
If no abnormality occurs when gantry is working, two axes will be in symmetry when performing
homing as shown in Figure 3.5.7.
