4 MP-Series Integrated Gear Motor Installation Instructions
Before You Install the Motor
1. Remove the motor carefully from its shipping container.
2. Visually inspect the motor for any damage.
3. Examine the motor frame and mounts, drive flange, mounting holes,
and dowel pin hole for any defects.
ATTENTION
!
Do not open or attempt to open the motor.
Only a qualified Rockwell Automation employee can
service this type of motor.
Failure to observe these safety procedures could result
in personal injury or damage to equipment.
Publication MP-IN003C-EN-P — April 2003
MP-Series Integrated Gear Motor Installation Instructions 5
Installing Your Motor
The installation must comply with all local regulations and use of
equipment and installation practices that promote electromagnetic
compatibility and safety.
All motors have a dowel pin hole for precisely aligning the motor output
on a machine. Bolt hole sizes are listed in Mounting Dimensions
beginning on page 10, and bolt torque requirements are listed in Housing
and Output Flange Connections beginning on page 22.
ATTENTION
!
ATTENTION
!
Unmounted motors, disconnected mechanical
connections, and disconnected cables are dangerous if
power is applied.
Disassembled equipment should be appropriately
identified (tagged-out) and access to electrical power
restricted (locked-out).
Before applying power to the motor, remove any
mounting bolts and screws, or other mechanical objects
which could be thrown from the motor.
Failure to observe these safety procedures could result in
personal injury.
Ensure that cables are installed and restrained to prevent
uneven tension or flexing at the cable connectors.
Excessive and uneven lateral force at the cable
connectors may result in the connector’s environmental
seal opening and closing as the cable flexes.
Failure to observe these safety procedures could result in
damage to the motor and its components.

6 MP-Series Integrated Gear Motor Installation Instructions
Guidelines for Installation
Observe the following guidelines when installing the motor.
ATTENTION
!
1. Allow sufficient clearances in the area of the motor for it to stay within
its specified operating temperature range 0° to 40° C (32° to 104° F).
Do not enclose the motor unless forced air is blown across the motor
for cooling. A fan blowing air across the motor will improve its
performance. Keep other heat producing devices away from the motor.
ATTENTION
!
Damage may occur to the motor bearings, gearing, and
the feedback device if sharp impact to the shaft is
applied during installation or removal of the motor.
Do not strike the MP gear motor with tools during
installation or removal.
Failure to observe these safety procedures could result in
damage to the motor and its components.
Outer surfaces of motor can reach high temperatures,
125° C (275° F), during motor operation.
Take precautions to prevent accidental contact with hot
surfaces. Consider motor surface temperature when
selecting motor mating connections and cables.
Failure to observe these safety procedures could result in
personal injury or damage to equipment.
2. Always position the motor with the connector housing pointing
downward.
Note: Gearbox input and output rotations are in identical directions.

3. Properly mount and align the motor.
A. Secure the motor to the machine mounting frame. Refer to:
• Mounting Dimensions beginning on page 10 for the bolt hole
pattern of your motor.
• Housing and Output Flange Connections beginning on page 22
for the torque values for connections.
B. Move the output flange so the motor feedback device aligns at its
electronic zero position. Encoder absolute position = 0 occurs when
the dowel pin hole is aligned on the connector side of the motor
and centered on the connectors. Refer to Figure 1 on page 11 for a
visual reference of this alignment.
IMPORTANT
Proper alignment and loading of the motor are critical to
achieving reliable operation throughout the lifetime of
the motor.
When mounting the MP-Series Integrated Gear Motor,
ensure that the connections are properly aligned and
that axial and radial loads are within the specifications of
the motor.
C. Connect the output flange to the machine’s drive assembly.
Mechanical connections to the motor flange must be rigid, secure,
and properly aligned. Refer to:
• Mounting Dimensions beginning on page 10 for the bolt hole
pattern of your motor.
• Housing and Output Flange Connections beginning on page 22
for the torque values for connections.
• Motor Load Force Ratings beginning on page 23 for guidelines to
achieve 20,000 hours of motor bearing life.
4. Apply a high-temperature, medium-strength threadlock adhesive to the
mounting bolts.

5. Attach all power, feedback, and brake cables after the motor is
mounted.
A. Use a drip loop in each cable to keep liquids flowing away from the
connectors.
IMPORTANT
Ensure that proper polarity is maintained when wiring a
brake connector.
The holding brake is designed to hold the motor shaft at
0 rpm and to release when power is applied - it is not
intended to stop motor rotation. Reversing the brake
polarity could cause the brake to be applied while the
motor is running. The section Holding Brake beginning
on page 27 provides information on the electrical
requirements for a brake motor.
Failure to observe proper polarity could result in damage
to the motor and its components.
B. Use Electromagnetic Compatibility (EMC) techniques to reduce
Electromagnetic Interference (EMI), commonly called noise. Noise
adversely impacts motor performance by inducing stray signals.
Effective techniques to counter EMI include filtering the AC power,
shielding and separating signal carrying lines, and practicing good
grounding techniques.
– Filter AC power by using isolated AC power transformers or properly
installed AC line filters.
– Physically separate signal lines from motor cabling and power wiring.
Do not route signal wires with motor and power wires, or over the
vent openings of servo drives.
– Ground all equipment using a single-point parallel ground system that
employs ground bus bars or large straps.
Refer to System Design for Control of Electrical Noise
(GMC-SG001x-EN-P) for information on additional electrical noise
reduction techniques.
6. If necessary, home the drive and motor system prior to use. Refer to
your drive instructions for procedures on when and how to do this.
