ControlLogix Drive
Modules (1756-DMxxx
Series)
The 1756-DM Drive Module is a single slot ControlLogix-based
module for interface to Reliance Electric Distributed Power System
(DPS) drive equipment. Each drive module interfaces with an
individual Power Module Interface (PMI) chassis, performing velocity,
position, and torque control.
There are six types of drive modules, one for each type of DPS drive
equipment. Table 3.1 lists the ControlLogix Drive modules.

Interface to Distributed Power System Drive Equipment
The first function of the Drive module is to interface to Reliance
Electric Distributed Power System (DPS) drive equipment, enabling
control of the drive equipment from a ControlLogix chassis. A
ControlLogix controller performs higher level control algorithms and
drive coordination. The Drive module performs outer control loop
processing, and the Power Module Interface (PMI) controller performs
real-time control of the Power Module.
Each drive module interfaces with an individual Power Module
Interface (PMI) chassis. It resides in a ControlLogix chassis and
connects to a PMI chassis via a fiber-optic Drive Communication
cable. This communication protocol is the same protocol used by a
Universal Drive Controller (UDC) (in an AutoMax environment) to
interface to a PMI controller.
