The 68-pin motion I/O connector provides all of the signals for four axes of
closed-loop motion control, including encoder feedback, limit and home
inputs, breakpoint outputs, trigger inputs, and analog-to-digital (A/D)
converter signals. Refer to Chapter 5,
the signals in the motion I/O connector.
The 68-pin digital I/O connector provides 32 bits of user-configurable
digital I/O. Refer to Chapter 5,
signals on the digital I/O connector.
The test connectors are proprietary interfaces for production testing and
troubleshooting. These connectors may or may not be installed during the
manufacturing process. Do not plug anything into these connectors.
With the 7344 controller properly installed, only two connectors are
typically used—the 68-pin motion I/O connector and the 68-pin digital
I/O connector. Cables and accessories provide connections to your motion
system.
Interface accessories for the 7344 family vary from the Universal Motion
Interface (UMI) units with signal conditioning and screw terminal
connectors to simple screw terminal blocks. Available drive units provide
pluggable connectors, power supplies, amplifier/drivers, and direct motion
system interfacing capabilities.
