AMIS-30621 LIN Microstepping Motordriver
Data Sheet
10.0 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 1/16th microstepping mode (see 8.5.1) 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.
