14.1.3. Position Periodicity
Depending on the stepping mode the position can range from –4096 to +4095 in half-step to –32768 to +32767 in 1/16
mode. 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 at a minimum.
Figure 9 illustrates that the moving direction going from ActPos = +30000 to TagPos = –30000 is clockwise.
If a counter clockwise motion is required in this example, several consecutive
movements, one could also use the command RunVelocity.
14.1.4. Hardwired Address HW
In Figure 10 a simplified schematic diagram is shown of the HW comparator circuit.
The HW pin is sensed via two switches S
connecting HW pin with a current to resistor converter. Closing S
R converter output is low, via the closed passing switch S

fed to the comparator. The output HW_Cmp will be high.
