This chapter describes how to make input and output signal connections
directly to the 7344/7334 and briefly describes the associated 7344/7334
I/O circuitry.
The 7344/7334 has three connectors that handle all signals to and from the
external motion system:
•
68-pin motion I/O connector
•
68-pin digital I/O connector
•
RTSI connector
You can connect to your motion system with cables and accessories,
varying from simple screw terminal blocks to enhanced UMI units and
drives.
The motion I/O connector contains all of the signals required to control up
to four axes of servo (7344 only) and stepper motion including the
following features:
•
Motor command analog and stepper outputs
•
Encoder feedback inputs
•
Forward, home, and reverse limit inputs
•
Breakpoint outputs
•
Trigger inputs
•
Inhibit outputs
This connector also contains four channels of 12-bit A/D inputs for analog
feedback or general-purpose analog input.
