Technical information

Product Overview

The motion control solution consists of three essential components that form the basic system.

The components are a FX Positioning Drive, DX Series Brushless Servo Motor and motor

cabling. This basic system can be enhanced with the addition of snap-on application modules

or peripheral equipment.

FX Drives

The FX drives are capable of driving motors with torque ratings from 8 to 400 lb-in (pounds-

inch) continuous output and speeds to 5000 RPM (revolutions per minute).

DX Motors

FX drives are sized to match certain DX motors. Many of the motors are available in metric

or English flange and shaft combinations. A holding brake is also available with most DX

motors.

Motor Cabling

Most models of motors are available with two standard styles of electrical connections. The

first style has “MS” (Military Specification) connectors; the second style has internal terminal

strips and NPT fittings. Pre-assembled cables for resolver feedback and stator wiring are

available for DX motors ordered with or without MS style connectors. DX motors without

MS style connectors with internal terminal strips meet IP65 waterproofing standards for

operation in a wash-down environment.

Resolver Cables

Pre-assembled resolver cables that connect the low voltage resolver and motor thermostat

signals from the DX motor to the FX amplifier are available in three standard lengths: 15, 25

and 50 feet (100 feet is the maximum cable length allowed without EMERSON Motion

Control factory approval.) There are two styles of resolver cables available for DX motors

(RC-XXX and ECF-XXX). The RC-XXX cable is used for motors without MS connectors

and the ECF-XXX cable is used for motors with MS connectors.

Stator Cables

For DX motors with MS style connectors, a stator cable, which carries the three stator wires,

ground wire and brake wires, is available in three standard lengths: 15, 25 and 50 feet. For

DX motors without MS style connectors, the stator wiring for the three motor phases and
