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.

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

, 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.

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.
