Frequently Asked Questions about 1746-HT
Question: What power connections are available on the 1746-HT termination panel?
Date Update:29/05/2025
Answer:

The panel supports external connections for +5 V, +15 V, and +24 V power from the system power supply. It also includes ground and return connections for each voltage level, along with encoder power and signal shielding. These power options support analog drives, encoders, and other motion components. The variety of voltage levels ensures compatibility with multiple servo hardware setups.

Question: How is the 1746-HT mounted and connected to the control system?
Date Update:29/05/2025
Answer:

The panel mounts on a DIN rail and can be positioned up to 2.1 meters (7 feet) away from the motion control module. It uses a combination of the 1746-HCA connector and standard wiring tools like a wire stripper and screwdriver. This setup enables fast installation and ease of maintenance in tight control enclosures. It occupies only one slot in the SLC rack.

Question: What diagnostic and control signals are integrated into the 1746-HT panel?
Date Update:29/05/2025
Answer:

The panel includes LED indicators that display the status of its digital input and output points. It features dedicated E-stop and drive enable connections, which enhance machine safety integration. The FAST I/O section includes three digital inputs and one output for time-sensitive events. These features make the panel suitable for high-speed motion applications.

Question: Does the 1746-HT support high-speed I/O?
Date Update:29/05/2025
Answer:

Yes, the panel includes three dedicated fast inputs and one fast output specifically designed for rapid-response tasks. These I/O points are used for precise control tasks, such as encoder triggering or emergency shutdown. Each input/output is tied to its own voltage and return line. Fast I/O contributes to real-time system responsiveness.

Question: Is the 1746-HT still in production?
Date Update:29/05/2025
Answer:

No, the 1746-HT termination panel is no longer in production and will be officially discontinued by Rockwell Automation on March 03, 2025. After this date, the product will no longer be available for purchase. There is currently no officially recommended Rockwell Automation replacement.
