Prolonging Motor Life
Proper design and maintenance can increase the life of a servo motor. Follow these guidelines to
maximize the life of a servo motor within your environment:
• Always provide a drip loop in each cable to carry liquids away from the connection to the
motor.
• If possible, provide shields that helps protect the motor housing, shaft seals, and their
junctions from contamination by foreign matter or fluids.
• Shaft seals are subject to wear and require periodic inspection and replacement.
Replacement is recommended every 3 months, not to exceed 12 months, depending on
use. See Shaft Seal Kits on page 22 for more information on shaft seals.
• Inspect the motor and seals for damage or wear regularly. If damage or excessive wear is
observed, replace the item.
• The brake option on this servo motor is a spring-set holding brake that releases when
voltage is applied to the brake coil. A separate power source is required to disengage the
brake. This power source is applied by a servo motor controller or manual operator
control.
If system main power fails, holding brakes can withstand occasional use as stopping
brakes. However, this creates rotational mechanical backlash that can damage the system,
increase brake wear, and reduce brake life.
IMPORTANT Holding brakes are not designed to stop rotation of the motor shaft, andthey are not
intended to be used as a safety device. They are designed to hold a motor shaft at 0 rpmfor
up to the rated brake holding torque.
Follow these steps to prevent motor shaft rotation.
1.Command the servo drive to 0 rpm.
2.Verify the motor is at 0 rpm.
3.Engage the brake.
4.Disable the drive.
Disabling the drive removes the potential for brake wear caused by a badly-tuned servo
system oscillating the shaft.
The cable enters beneath the
motor and forms a drip loop.
The cable enters above the
motor and does not form a
drip loop.

MP-Series Low-inertia Servo Motor with 100 mm to 165 mm Frame Size
Using Shaft Seals
An additional seal is required on the motor shaft near the motor front bearing if the shaft is
exposed to fluids or significant amounts of fine dust. This includes lubricating oil from a
gearbox. An IP66 rating for the motor requires the use of a shaft seal and environmentally sealed
connectors/cables. The additional seal is not recommended in applications where the motor
shaft area is free of liquids or fine dust, and a lower rating is sufficient:
•SeeSpecifications on page 23 for a brief description of the IP rating for these MP-Series
motors.
•SeeShaft Seal Kits on page 22 to find the catalog numbers of seal kits available for your
motor.
• See Kinetix® Motion Accessories Specifications, publication KNX-TD004, to find
environmentally sealed connectors and cables compatible with the MP-Series motors.
Using Couplings and Pulleys
Mechanical connections to the motor shaft, such as couplings and pulleys, require a torsionally
rigid coupling or a reinforced timing belt. The high dynamic performance of servo motors can
cause couplings, pulleys, or belts to loosen or slip over time. A loose or slipping connection can
cause system instability and damage the motor shaft. All connections between the system and the
servo motor shaft must be rigid to achieve acceptable response from the system. Periodically
inspect connections to verify their rigidity.
When mounting couplings or pulleys to the motor shaft, be sure that the connections are
properly aligned and that axial and radial loads are within the specifications of the motor.
See Motor Load Force Ratings on page 17 for guidelines to achieve 20,000 hours of motor
bearing life.
ATTENTION: Damage can occur to the motor bearings and the feedback device if sharp impact
to the shaft is applied during installation of couplings and pulleys. Damage to the feedback
device can result by applying leverage from the motor mounting face to remove devices
mounted on the motor shaft.
Do not strike the shaft, couplings, or pulleys with tools during installation or removal. Use a
wheel puller to apply pressure from the user end of the shaft and remove any friction-fit or
stuck device from the motor shaft.

MP-Series Low-inertia Servo Motor with 100 mm to 165 mm Frame Size
Preventing Electrical Noise
Electromagnetic interference (EMI), commonly called noise, can cause poor motor performance
by inducing stray signals.
Follow these guidelines to prevent the effects of EMI:
• Isolate the power transformers, or install line filters on all AC input power lines.
• Separate signal cables from motor cabling and power wiring. Do not route signal cables
with motor and power wires, or over the vent openings of servo drives.
• Ground all equipment by using a single-point parallel ground system that employs
ground bus bars or large straps. If necessary, use additional electrical noise reduction
techniques to reduce EMI in noisy environments.
See System Design for Control of Electrical Noise Reference Manual, publication
GMC-RM001, for additional information on reducing the effects of EMI by improving the
system level electromagnetic compatibility (EMC).
Build and Install the Cables
Correct cable routing and careful cable construction improve system electromagnetic
compatibility (EMC).
Follow these guidelines to build and install the cables:
• Keep the wire lengths as short as possible.
• Route noise sensitive wiring (encoder, serial, and I/O) away from input power and motor
power wiring.
• Separate cables by 0.3 m (1 ft) minimum for every 9 m (30 ft) of parallel run.
• Ground both ends of the encoder cable shield and twist the signal wire pairs to help
prevent EMI from other equipment.
ATTENTION: High voltage can be present on the shield of a power cable, if the shield is not
grounded.
Verify that thereis a connection to ground for any power cable shield.
ATTENTION: MP-Series motors produce leakage current in the protective earthing conductor
that exceeds 3.5 mA AC and/or 10 mA DC.
Be sure to properly ground the motor cables per the drive installation instructions.

MP-Series Low-inertia Servo Motor with 100 mm to 165 mm Frame Size
Ground Shielded Signal Wires Within a Power Cable
Always connect the shield on any signal wire pair that is routed inside a power cable to the overall
machine ground.
If you are installing a 2090-XXNPMF-xxSxx or 2090-CPBM4DF-xxAFxx power with brake
cable, loop the signal wire pairs to the overall cable shield as shown in Grounding of Signal Wire
Shields in a Power Cable on page 7. Then clamp all shields together in the power cable (chassis)
ground connection on the drive.
Grounding of Signal Wire Shields in a PowerCable
The signal wire pairs within a power cable often carry a 24V DC brake signal, but can also carry
logic signals. Grounding the shield that surrounds the signal wires dissipates an induced voltage
and reduces the effects of EMI.

Install the Motor
MP-Series motors include a mounting pilot for aligning the motor on the machine. Preferred
fasteners are stainless steel. The installation must comply with all local regulations and use
equipment and installation practices that promote safety and electromagnetic compatibility.
Change the Orientation of the Connectors
MP-Series motors use two styles of connectors. The connector style is identified by a 2 or a 7 as
the connector variable in the motor catalog number. For example, MPx-xxxxx-xx2xxx or
MPx-xxxxx-xx7xxx:
• A 2 indicates a circular bayonet connector, facing the shaft.
• A 7 indicates a circular DIN, right angle, rotatable connector.
RotatableCircularDIN Connector(catalognumberMPL-xxxxx-xx7xxx)
The circular DIN connector housing can be rotated up to 180° in either direction.
Follow these steps to turn the DIN connectors.
1. Mount and fully seat a mating cable on the connector.
ATTENTION: Unmounted motors, disconnected mechanical couplings, loose shaft keys, and
disconnectedcables are dangerous if power is applied.
Lock-out and tag-out disassembled equipment (restrict electrical power).
Before applying power to the motor, remove the shaft key and other mechanical couplingsthat
can be thrown from the shaft.
ATTENTION:Makesurethatcables areinstalled and restrained tohelp preventuneven tension
or flexing at the cable connections.
Excessive anduneven lateral force on the cable can inhibit environmental sealing as the cable
flexes.
ATTENTION: Connectors are designed to be rotated into a fixed position during motor
installation, and remain in that position without further adjustment. Do not rotate the
connector multiple times, and do not use tools or excessive force to rotate the connector.
Excessive rotation or force can damage the connector seal and reduce the international
protection (IP) rating of the motor as outlined in Specifications on page 23.

Rockwell Automation Publication MP-IN001J-EN-P - June 2018 9
MP-Series Low-inertia Servo Motor with 100 mm to 165 mm Frame Size
2. Grasp both connectors by their housings and slowly rotate them to the outside of the
motor.
If necessary, repeat this step for each connector (feedback or power/brake).
Apply force to only the connectors; do not apply force to the cable. Do not use tools (for
example, pliers and vise-grips) to rotate the connector.
Mount the Motor
Follow these steps to mount the motor.
1. Provide sufficient clearance, heatsink mass, and airflow for the motor so it stays within
the operating temperature range of 0…40 °C (32…104 °F).
Do not enclose the motor unless forced air is blown across the motor for cooling. Keep
other heat producing devices away from the motor. Heatsink requirements are listed in a
footnote to the Specifications on page 23.
2. Verify the axial and radial shaft loads of your application do not exceed those listed in
the Motor Load Force Ratings on page 17.
3. Place the motor with the connector housing pointing downward.
4. Mount and align the motor.
Electronic zero (index pulse or Stegmann ABS = 0) occurs when the shaft key or dimple
is aligned with the connectors.
ATTENTION: Damage can occur to the motor bearings and the feedback device if sharp impact
to the shaft is applied during installation of couplings and pulleys.
Do not strike the shaft, couplings, or pulleys with tools during installation or removal.
ATTENTION: Outer surfaces of the motor can reach high temperatures of
125 °C (257 °F) during operation.
Take precautions to help prevent accidental contact with hot surfaces. Consider
motor surface temperature when selectingmotor mating connections and cables.

MP-Series Low-inertia Servo Motor with 100 mm to 165 mm Frame Size
Attach the Motor Cables
Follow these steps to attach the feedback and power/brake cables after the motor is mounted.
1. If you are using the Threaded DIN (M4) Cable Plugs, install the O-rings.
An O-ring on the connector is necessary to achieve the maximum environmental rating.
2. If you are using the SpeedTec DIN (M7) Cable Plugs, do not install the O-rings.
3. Form a drip loop in the cable (see page 4).
ATTENTION: Servo drive power must be turned off before connecting or disconnecting the cables
to the motor, and if a cable is left disconnected at the motor end.
Arcing or unexpected motion can occur if the feedback, power, or brake cables are connected or
disconnected while power is applied to the servo drive.
ATTENTION: Be sure that cables are installed and restrained to help prevent uneven tension or
flexing at the cable connectors. Provide support at 3 m (10 ft) intervals throughout the cable run.
Excessive and unevenlateral force at the cable connectors can result in the connector’s
environmental seal opening and closing as the cable flexes, or wires separating at the cable gland.

4. Carefully align the flat surface on the feedback or the power/brake cable plug (shown in
the diagram) with the flat surface on the motor connector.
5. Hand tighten the collar on the plug to fully seat it on the connector:
• Threaded DIN (M4) cable plugs require five to six revolutions.
• SpeedTec DIN (M7) cable plugs require approximately one-quarter of a revolution.
Do not apply excessive force when mating the cable plug with the motor connector. If the plug
and connector do not go together with light hand force, realign the flat surfaces and try again.
IMPORTANT The motor orientation that is shown is used to show the alignment marker on each
cable socket.
The recommended motor orientation when installed positions the connectors at the
bottom of the motor.
TIP A fully-seated threaded plug leaves a small opening, approximately 1…4 mm
(0.04…0.16 in.), between the connector and the plug.
ATTENTION: Align the keyed connectors and hand-tighten the recommended number of turns.
If you cannot tighten the connectors by hand, verify that the keyed connectors are properly
aligned. Do not use tools (for example, pliers and vise-grips) totighten the connectors.

MP-Series Low-inertia Servo Motor with 100 mm to 165 mm Frame Size
Motor Load Force Ratings
Motors are capable of operating with a sustained shaft load. The radial and axial load force
location is shown in the figure, and maximum values are in the tables.
Load Forces on Shaft
The following tables represent 20,000 hour L10 bearing fatigue life at various loads and speeds.
This 20,000 hour life does not account for possible application-specific life reduction that can
occur due to bearing grease contamination from external sources.
