4 MP-Series Stainless Steel Servo Motor with 100 mm to 165 mm Frame Size
About the MP-Series Stainless Steel Servo Motor
The MP-Series™ stainless steel (Bulletin MPS) motors are designed to meet the unique needs of
hygienic manufacturing environments such as food, beverage, brewing, dairy, health and beauty,
and pharmaceutical products.
Before You Begin
Remove all packing material from within and around the item. After unpacking, verify the
nameplate catalog number against the purchase order.
1. Remove the motor carefully from its shipping container.
2. Visually inspect the motor for any damage.
3. Examine the motor frame, front output shaft, and mounting pilot for any defects.
4. Notify the carrier of any shipping damage immediately.
Keep the original packing material in case you need to return the product for repair or transport
it to another location. Use both the inner and outer packing cartons to provide adequate
protection for a unit returned for service.
ATT ENT IO N: Do not attempt to open and modify the motor. This manual describes modifications that you can
perform in the field. Do not attempt other changes.
Only an authorized Allen-Bradley repair center can service this item. Refer to Rockwell Automation Support for
assistance to locate the nearest repair center.
Store or operate your motor in a clean and dry location within the environmental conditions
listed in Motor Cables and Accessory Kits
on page 22.
To Prolong 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:
ATT ENT IO N: Do not spray liquids under high pressure directly on the connectors, the motor, or enclosure joints.
Fluids under high pressure can be forced into the connectors, resulting in an electrical short circuit. Fluids also can
be forced around worn seals, and contaminate the motor bearings. Bearing contamination significantly shortens
the life of a servo motor.
The motor has 3 m (9.8 ft) cables with nickel-plated connectors for motor power and feedback. These connec tors
are not designed to withstand high pressure washdown or washdown with aggressive cleaning compounds.
Position connectors away from direct exposure to cleaning processes, for example within washdown-rated conduit
or junction boxes.

MP-Series Stainless Steel Servo Motor with 100 mm to 165 mm Frame Size 5
IMPORTANT
The cable enters beneath the motor and
forms a drip loop.
The cable enters above the motor
and does not form a drip loop.
• Always provide a drip loop in each cable to carry liquids away from the connection to the
motor.
• If possible, provide shields that protect the motor housing, shaft seals, and their
junctions from product contamination, caustic agents, and high pressure 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. Refer to Shaft Seal Kits on page 22 for more information on shaft seals.
• Inspect the motor and seals for damage or wear on a regular basis. If damage or excessive
wear is observed, replace the item.
• You can seal the motor front flange to the driven equipment by applying a bead of food
grade RTV around the periphery of the joint between the motor and the machine
surfaces. Use of a gasket or RTV on the mating surfaces is not recommended, as this can
cause misalignment of the shaft and result in damage to the motor and/or driven
equipment.
• 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 can be 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 cause damage to
the system, increase brake wear, and reduce brake life.
Holding brakes are not designed to stop rotation of the motor shaft, and they are not intended to be used as a
safety device. They are designed to hold a motor shaft at 0 rpm for 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.

6 MP-Series Stainless Steel 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, IP67, or IP69K 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:
• Refer toSpecifications on page 24 for a brief description of the IP rating for these
MP-Series motors.
• Refer toShaft Seal Kits on page 22 to find the catalog numbers of seal kits available for
your motor.
• Refer to Kinetix® Motion Accessories Specifications, publication GMC-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. Refer
to Shaft Seal Kits
for guidelines to achieve 20,000 hours of motor bearing life.
ATT EN TI ON : 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 whee l puller
applying pressure from the user end of the shaft to remove any friction-fit or stuck device from the motor shaft.

Preventing Electrical Noise
Electromagnetic interference (EMI), commonly called noise, can adversely impact 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.
Refer to System Design for Control of Electrical Noise Reference Manual, publication
GMC-RM001
system level electromagnetic compatibility (EMC).
, for additional information on reducing the effects of EMI by improving the
Build and Install the Cables
Correct cable routing and careful cable construction improves 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 prevent
EMI from other equipment.
ATT ENT IO N: High voltage can be present on the shield of a power cable, if the shield is not grounded.
Verify that there is 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.

Power cable contains two paired signal wires, each with a separate
ground shield, in addition to the U, V, and W power wires. A brake
motor uses one wire pair for the brake signals.
Cable insulation is removed to expose the overall shield of the cable.
Loop the signal wires and shielding to contact the overall power-cabl
shield.

Fac tory Supp lied
Power Cable
Field Modified Power
Cable
Connect shields to the power-cable ground clamp on the drive. The
drive clamp must contact all (overall, signal, and brake) cable
shields.
Catalog number 2090-XXNPMF-xxSxx is shown.
Power Cable Shielding
Power cables must be shielded, and the cable shield connects to ground.
ATTENTION: High voltage can be present on the shields of a power cable, if the shields are not grounded.
Verify there is a connection to ground for all shields in the power cable.
Verify the separate signal-wire shield connect to the overall chassis ground by looping back each
of the signal wire pairs as shown in Shielding of Signal Wires within a Power Cable
Clamp all three shields together at the power cable (chassis) ground connection on the drive.
Shielding of Signal Wires within a Power Cable
on page 8.
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.
ATT EN TI ON : Unmounted motors, discon nected mechanical couplings, loose shaft keys, and disconnected
cables are dangerous if power is applied.
Lock-out and tag-out disassembled equipment (restrict elec trical power).
Before applying power to the motor, remove the shaft key and other mechanical couplings that can be thrown
from the shaft.
ATT EN TI ON : Make sure that cables are installed and restrained to prevent uneven tension or flexing at the
cable connections.
Excessive and uneven lateral force on the cable can inhibit environmental sealing as the cable flexes.
Mount the Motor
Follow these steps to mount the motor.
ATT EN TI ON : 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.
1. Provide sufficient clearance, heatsink mass, and air flow for the motor so it stays within
the operating temperature range of 0…40 °C (32…104 °F).
Do not enclose the motor unless cooling air is forced across the motor, and keep other
heat producing devices away from the motor. Heatsink requirements are listed in a
footnote to the Motor Cables and Accessory Kits
table.
ATTENTION: Outer surfaces of the motor can reach high temperatures of 125 °C (275 °F) during
operation.
Take precautions to prevent accidental contact with hot surfaces. Consider motor surface temperature
when selecting motor mating connections and cables.
2. Verify the axial and radial shaft loads of your application do not exceed those listed in the
Motor Load Force Ratings
.
3. Position the motor with the cable connections beneath the motor.
Refer to To Prolong Motor Life
on page 4 for a visual reference of correct motor and
cable positioning.
4. Properly mount and align the motor.
The index pulse occurs on a single-turn encoder when the shaft key is aligned with the
connectors. Refer to Product Dimensions
on page 12 for a visual reference of this
alignment.

Attach the Motor Cables
Follow these steps to attach the feedback and power/brake cables after the motor is mounted.
ATT EN TI ON : 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.
ATT EN TI ON : Be sure that cables are installed and restrained to prevent uneven tension or flexing at the cable
connectors. Provide support at 3 m (10 ft) intervals throughout the cable run.
Excessive and uneven lateral 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.
1. Verify the seal and O-rings are installed as shown in the diagram.
An O-ring on the feedback connector, and a backshell seal on the feedback and
power/brake connector, is necessary to achieve the maximum environmental rating.
Publication MP-IN005F-EN-P - January 2014
• A backshell seal covers the joint inside the feedback
and power/brake housings. It seals the joint
between the backshell and the housing of the
connector.
• Verify that the backshell seal is not damaged, and it
is fully seated against the face of the backshell.

2. Form a drip loop in the cable (see page 5
).
3. 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.
4. 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.
A fully-seated threaded plug leaves a small opening, approximately 1…4 mm (0.04…0.16 in.),
between the connector and the plug.
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.
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) to tighten the connectors.

Remove and Install a Shaft Key
Shaft keys for the Bulletin MPS motors are constructed of stainless steel - 300 series. The
specified tolerance provides an interference fit (slightly larger than the opening) for a secure and
rigid connection.
ATT EN TI ON : Do not strike the motor’s shaft, couplings, or pulleys with tools during installation or removal of the
shaft key.
Damage can occur to the motor bearings and the feedback device if a sharp impact is applied to the shaft during
installation of couplings and pulleys, or to remove the shaft key, or if leverage is applied from the motor mounting
face to remove devices mounted on the motor shaft.
Apply a constant pressure, with a wheel puller, to the user end of the shaft to remove a friction fit or stuck device.
To remove a shaft key, perform one of these actions:
• Lift the key by grasping it with a pliers or similar tool.
• Lever the key with a screwdriver inserted between the key and the slot.
To install a shaft key, follow these steps.
1. Verify the replacement key matches the keyway in the shaft and the mating mechanical
connection (for example, a coupling or pulley) before proceeding.
2. Align the front of the key with the front of the motor shaft.
This prevents the radiused end-of-cut at the motor end of the keyway from interfering
with correct seating of the key.
3. Support the underside of the shaft diameter with a fixture, and use a controlled press
device to apply a constant force across the top surface to press the key into the shaft.

Slinger and Shaft Seal Removal and Installation
The slinger and a shaft seal provide environmental sealing for Bulletin MPS motors. The slinger
shields the shaft seal from contact with the full force of high-pressure cleaning fluids, while the
shaft seal provides a secondary barrier to moisture and particle intrusion that protects the motor
bearings. Bulletin MPS motors are shipped with a plastic slinger and PolyTetraFluoroEthylene
(PTFE) shaft seal installed.
Lubricate the shaft seals with a food-grade polyurea base grease, such as Chevron
Lubricant is included in each shaft seal kit.
ATTENTION: Damage to the motor surface where the slinger and shaft seals make contact can cause excessive
wear and early failure of the slinger and shaft seal. Use care to prevent scratching or damaging the surface of the
motor or the shaft.
Remove the slinger and shaft seal by performing the following procedures. If a sealed gearbox is
to be attached to the motor shaft, perform only the Remove the Slinger on page 19 procedure.
Remove the shaft key, if the motor is so equipped, before performing the following steps. Refer to Remove and
Install a Shaft Key on page 18.
FM (NLGI 2).
Refer to Shaft Seal Kits
on page 22 for a list of kits. A slinger is included in each shaft seal kit.
Remove the Slinger
1. Use two screwdrivers to carefully lever the slinger away from the faceplate of the motor.
You must create sufficient clearance to attach a wheel-puller, or a similar device
underneath the slinger.
Do not scratch or damage the motor shaft or mounting surface.
2. Center the wheel-puller on the motor shaft and position its arms under the slinger.
3. Slowly adjust the wheel-puller to lift the slinger off the motor shaft.
4. Dispose of the used slinger.
Do not contaminate other surfaces or objects with foreign material from the sling er.

TIP
Remove the Shaft Seal
The shaft seal can be safely removed by partially inserting an appropriately sized screw or bolt
into the face of the shaft seal. The head of the screw or bolt provides a convenient point to grasp
and remove the shaft seal.
Before installing the screw, create a pilot hole appropriate for the screw being used. Use masking
tape or a depth sleeve to establish a drilling depth limit of 4 mm (0.16 in.) from the tip of the drill
bit.
ATT EN TI ON : Do not drill into the shaft seal deeper than 4 mm (0.16 in.).
Drilling and inserting a screw completely through the shaft seal can damage the motor bearings, and require
factory service to repair the motor.
1. Drill a pilot hole in the face of the shaft seal less than the depth limit specified above.
Be sure the drill does not come in contact with the shaft seal bore.
2. Thread the screw or bolt into the pilot hole.
3. Lift the shaft seal from the motor by grasping the screw head and slightly rotating the
seal while pulling.
4. Inspect and clean the shaft and sealing surfaces as necessary.
Replace the Shaft Seal
No tools are required to install the replacement shaft seal.
1. Apply the provided grease to the inner ring of the shaft seal and motor shaft.
2. Center the shaft seal on the mounting surface of the motor with the seal oriented in the
same manner as the removed seal.
3. Press the shaft seal into the seal recess by applying pressure with your fingertips in a
circular fashion to slowly seat the shaft seal in place.
4. Verify the outer and inner circumference of the shaft seal is fully seated into position.
You can verify the proper seating of the shaft seal by running a fingertip around the seal-to-motor joint to feel
for irregularities in the shaft seal or an uneven alignment where the shaft seal contacts the motor.

5. Tighten the nut to force the washer, socket, and slinger down the shaft.
Grasp the slinger tightly by hand to prevent shaft and slinger rotation in the next steps.
If additional travel is required to seat the slinger, add a section of hollow pipe or a similar
item behind the socket.
6. Stop moving the slinger down the shaft approximately 3 mm (0.125 in.) before the
slinger contacts the mounting surface of the motor.
