Figure 12. Simplified Schematic Diagram of the SWI Comparator
As illustrated in the drawing above, a change in state is
always synchronized with DriveHS or DriveLS. The same
synchronization is valid for updating the internal position
register. This means that after every current pulse (or closing
of S TOP or S BOT ) the state of the position switch together
with the corresponding position is memorized.
The GetActualPos command reads back the <ActPos>
register and the status of ESW. In this way the master node
may get synchronous information about the state of the
switch together with the position of the motor. See Table 16
below.
