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_A1_LMT+),
the RELAY (indicated as R_A1_LMT+) will be activated. At this time,
the NORMAL OPEN switch (R_A1_LMT+)(in zone B) will close and
enable the current to flow into the A1_LMT+ point on the SCSI-II 68-
pin connector. Now, the reading of A1_LMT+ 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).
