Description

The Allen-Bradley 1756-DMF30 is a specialized single-slot drive interface module designed for the ControlLogix platform. This module functions as a high-speed communication and control bridge between a ControlLogix processor and the Reliance Electric Distributed Power System (DPS) hardware. It coordinates complex outer-loop control algorithms, including precise torque, position, and velocity control, by interfacing directly with a field-mounted Power Module Interface (PMI) chassis via a dedicated fiber optic link.

Features

• Designed for seamless integration with the ControlLogix backplane.
• Supports high-speed communication for complex drive control loops.
• Fiber optic interface for reliable communication with remote PMI chassis.
• Optimized for legacy Reliance Electric drive system migrations.

Drive System Compatibility

The 1756-DMF30 is engineered to support legacy high-power Reliance Electric drive systems, including:

• SD3000 6-Pulse DPS: Interfaces with S6 DC drives and S6R resolver assemblies.
• SD3000 12-Pulse DPS: Connects with S12 DC drives and S12R resolver configurations.

Technical Specifications

Installation Guidelines

• Ensure the ControlLogix chassis is powered down before inserting or removing the module.
• Handle the module using proper ESD (Electrostatic Discharge) precautions.
• Ensure the module is fully seated in the chassis slot and secured with the top and bottom mounting screws.
• Route fiber optic cables away from high-voltage power lines to prevent EMI interference.
• Maintain adequate clearance around the chassis for proper ventilation and thermal management.

FAQ

What is the primary function of the 1756-DMF30?

The 1756-DMF30 acts as a communication bridge between a ControlLogix controller and Reliance Electric Distributed Power System (DPS) hardware, enabling advanced drive control functions.

Does this module require external power?

No, the module draws its power directly from the ControlLogix backplane (5.1V DC and 24V DC).
