10. Features
10.1. Position periodicity
Depending on the stepping mode the position can range between –4096 to +4095 in half-step mode to –32768
to +32767 in 1/16^th microstepping mode (see § 8.5.1 Position ranges) one can project all these positions lying on
a circle. When executing the command SetPosition the position controller will set the movement direction in
such a way that the traveled distance is minimum.
As an example in the figure below is illustrated the moving direction going from ActPos = +32700 to SetPos = –
32700 is counter clockwise.
If a clockwise motion is required in this example, several consecutive SetPosition commands can be used.
-32700
+32700
