3.6 Local I/O Wiring Example
In this section, it shows a local I/O wiring example of PCI-1241/42 that
helps you to setup a system quickly. Figure 3-8 and Figure 3-9 show
examples of PCI-1241/42 local I/O wiring diagram of axis one. In the
example, all input channels are configured as source type. (Short pin 1
and pin 2 of JP6).
• Please refer to A zone:
When the first axis moves through the limit switch (LS),
the RELAY (indicated as R) will be activated. At this time,
the NORMAL OPEN switch (R)(in zone B) will close and
enable the current to flow into the point on the SCSI-II 68-
pin connector. Now, the reading of on PCI-1241/42 will
change from 1 to 0.
• For the same reason as above, zone C and zone D are for the negative-
direction limit switch (LS_A1_LMT-). Zone E and zone F are for the
home limit switch (LS_A1_HOME).
