9.2.1.3 External Switch and HW Pin
Pin SWI and hardwired address pin HW (see § 9.2.4.3
Physical Address) will alternatively attempt to source and
sink a current in/from the external switch (see application
schematic) to test whether it is ON or OFF. This current is
set around 10mA when a 1k
external series resistor is
used.
This can be represented by the following time diagram (the
timings are given in § 6).
If the switch is detected ON (closed), then the flag
<ESW>
is
raised. The status of this flag can be read by the application
via a
GetActualPos
or a
GetFullStatus1
reading
frame. At the falling edge of every current pulse (at around
1kHz), the stepper motor actual position is refreshed
(register ActPos, see § 9.2.2.9), so that the master node
may get synchronous information about the state of the
switch together with the position of the motor. The position
is then given with an accuracy of ± 1 half-step (or micro-
step, depending of the programmed stepping mode). The
block diagram below shows how this function is
implemented for HW.

Note
If HW is detected to be floating, motion to the secure position is performed.
note that e.g. if HW is connected
to GND, LS-part will report "float"
while HS-part will report "low
resistance detected".
