Motion I/O Connector
The motion I/O connector contains all signals necessary for controlling
axes of servo and stepper motion, including the following features:
•
Encoder feedback inputs
•
Forward, home, and reverse limit inputs
•
Trigger inputs
•
Motor command analog and stepper outputs
•
Breakpoint outputs
•
Inhibit outputs
The motion I/O connector also contains two channels of 12-bit A/D inputs
for analog feedback or general-purpose analog input.
Figure 5-2 shows the pin assignments for the 68-pin motion I/O connector
on the PCI-7342 controller. Refer to Table 5-1 for a description of each
motion I/O signal.
Note
Lines above signal names indicate that the signal is active-low.
