R2VBAT
A resistor is connected between VBAT and HW. Every 1024μs S
of the I
interpret this as a change of state and the new state will be High (see also Table 15). The next time S
observed. The previous state was high, so based on Table 15 the new state remains unchanged. This high state will be interpreted as
HW address = 1.
OPEN
In case the HW connection is lost (broken wire, bad contact in connector) the next time S
no current, the output of the corresponding I
on Table 15 one can see that the state changes to float. This will trigger a motion to secure position after a debounce time of 64 ms.
This prevents false triggering in case of micro interruptions of the power supply. See also
Lines.
R2GND
If a resistor is connected between HW and the GND, a current is sensed every 1024μs when S
R converter is low and as a result the HW_Cmp output switches to high. Again based on the stated diagram in Table 15 one can see
that the state will change to low. This low state will be interpreted as HW address = 0.
14.1.5. External Switch SWI
As illustrated in Figure 12, the SWI comparator is almost identical to HW. The major difference is in the limited number of states. Only
open or closed is recognised leading to respectively ESW = 0 and ESW = 1.
As illustrated in Figure 14, 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
together with the corresponding position is memorized.
Using the GetActualPos commands 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 Figure 13.
