3.5.2.3 Motion Following
When completing positioning and returning to the homing origin, the host controller has to issue
position commands. Then, ASDA-A2 will synchronize the motion of the two axes with its
remarkable performance. When reaching the position, ASDA-A2 is able to report its arrival to the
host controller. In this gantry control, ASDA-A2 is operated in PT mode; it does not accept the
position command from the host to speed up or slow down. Therefore, the host controller itself
should plan the acceleration/deceleration time to achieve stability and efficiency.
