Figure 12. Simplified Schematic Diagram of the SWI Comparator
As illustrated in the drawing above, a change in state is
always synchronised with DriveHS or DriveLS. The same
synchronisation 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 memorised.
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.
