About the MP-Series Food Grade Motors

MP-Series food grade (MPF) motors feature single-turn or multi-turn high resolution
encoders, and are available with 24V DC brakes. These compact brushless servo
motors combine the characteristics of the MP-Series low-inertia motors with unique
features designed for food and beverage applications.

Before You Begin

Remove all packing material, wedges, and braces 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 frame, shaft, mounting pilot, and encoder for

damage.

3. Notify the carrier of any shipping damage immediately.

Do not attempt to open or modify this motor beyond changing the connector
orientation as described in Change Connector Orientation

Failure to observe safety precautions could result in personal injury or damage to
equipment.

.

Prolonging Motor Life

Thoughtful design and proper maintenance can increase the life of a servo motor.
Follow these guidelines to maximize the life of a servo motor within a food
processing environment.

• Always provide a drip loop in each cable to carry liquids away from the
connection to the motor.

• Avoid spraying liquids under high pressure directly on the junction of the
motor shaft, housing, connectors, and the enclosure joints. Fluids under high
pressure, when forced around worn seals, can contaminate the motor
bearings and significantly shorten the life of a servo motor.

• If design requirements permit, provide shields that protect the motor
housing, shaft, seals and their junctions from product contamination, caustic
agents, and high pressure fluids.

• Replace the shaft seal at or before its expected lifetime of 12 months.
Refer to Shaft Seals

for more information on shaft seals.

Publication MP-IN004D-EN-P — April 2009

MP-Series Food Grade Servo Motor Installation Instructions 5

IMPORTANT

• Inspect the motor and seals for damage or wear on a regular basis. If
damage or excessive wear is observed, replace the item.

• If desired, you may 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 is
potentially damaging to the system, increases brake wear, and reduces brake
life.

Holding brakes are not designed to stop rotation of the motor shaft, nor are they
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.

The recommended method of preventing motor shaft rotation is a four step
process: first - command the servo drive to 0 rpm, second - verify the motor is at
0 rpm, third - engage the brake; and fourth - 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

A seal is installed on the motor shaft to protect the front bearing from fluids or fine
dust that could contaminate the motor bearing and reduce its lifetime. An IP66/IP67
rating for the motor requires the use of shaft seals, connectors, and cables that
provide an environmental seal equal to or exceeding the rating.

• Refer to Specifications

• Refer to Shaft Seals

• Refer to the Kinetix Motion Control Selection Guide, publication

GMC-SG001

, to find environmentally sealed connectors and cables that are

compatible with MP-Series motors.

ATTENTION

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 causes system instability and can damage
the motor shaft. All connections between the system and the servo motor shaft must
be rigid to achieve an acceptable response from the system. Periodically inspect
connections to verify their rigidity.

When mounting couplings or pulleys to the motor shaft, make sure that the
connections are properly aligned and that axial and radial loads are within the
specifications of the motor. Refer to Shaft Seals
hours of motor bearing life.

Damage may occur to the motor bearings and the feedback device if sharp impact is applied
to the shaft during installation of couplings and pulleys. Damage to the feedback device
may result from applying leverage to the motor mounting face when removing 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 to remove any device from the
motor shaft.

Failure to observe safety precautions could result in damage to the motor and its
components.

Preventing Electrical Noise

ElectroMagnetic Interference (EMI), commonly called electrical noise, can reduce
motor performance. Effective techniques to counter EMI include filtering the AC
power, use of shielded cables, separating signal cables from power wiring, and
practicing good grounding techniques.

Follow these guidelines to avoid the effects of EMI:

• Isolate the power transformers or install line filters on all AC input power
lines.

• Physically 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 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.

Install the Motor

All 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.

Unmounted motors, disconnected mechanical couplings, loose shaft keys, 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 the shaft key and other mechanical couplings
which could be thrown from the shaft.

Failure to observe safety precautions could result in personal injury.

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 result in the environmental seal
opening and closing as the cable flexes.

Failure to observe safety precautions could result in damage to the motor and its
components.

Verify Connector O-ring and Backshell Seal

O-rings on the feedback and motor/brake connectors secure cable plugs, and a
backshell seal on the feedback connector is necessary to achieve the maximum
environmental rating. Verify the seal and O-rings are installed as described.

Location Verify

• An O-ring is mounted on the external surface of

both the power/brake connector and the
feedback connector.

• The O-ring is undamaged, not twisted, and rests

in the groove as shown in the illustration.

• A backshell seal covers the joint between the

backshell and the connector housing.

Publication MP-IN004D-EN-P — April 2009

• The backshell seal is undamaged, and it is fully

seated against the face of the backshell.

ATTENTION

IMPORTANT

ATTENTION

Change Connector Orientation

You may rotate the connector housing up to 180 degrees. This lets you adjust the
connector to a position that best protects the connection from possible
environmental contaminates while providing cable access.

Connectors are designed to be rotated into a fixed position during motor installation, and
remain in that position without further adjustment. Strictly limit the applied forces and the
number of times the connector is rotated to make sure that connectors meet the
requirements of IP66 and IP67.

Failure to observe safety precautions could result in damage to the motor and its
components.

Do not use tools, such as pliers or vise-grips, to assist you in rotating the connector.
Only apply force to the connector. Do not apply force to or pull on the cable.

The circular DIN connector housing can be rotated up to 180° in either direction.

Follow these steps to rotate a DIN connector.

1. Mount and fully seat a mating cable on either the feedback or power/brake

connector.

2. Grasp the mated connector and cable plug and slowly rotate them to the

outside of the motor.

Apply force only to the motor connector and cable plug. Do not apply force to
the cable extending from the cable plug. No tools, for example pliers or
vise-grips, should be used to assist with the rotation of the connector.

Failure to observe safety precautions could result in damage to the motor and
its components.

3. Repeat these steps for the other connector.

ATTENTION

Build and Route the Cables

Knowledgeable cable routing and careful cable construction improves system
performance.

Build and install cables as described in these steps.

1. Keep wire lengths as short as physically possible.

2. Route noise sensitive wiring (encoder, serial, I/O) away from input power

and motor power wiring.

3. Separate cables by 0.3 m (1 ft) minimum for every 9 m (30 ft) of parallel run.

4. Ground both ends of the encoder cable shield and twist the signal wire pairs

to prevent electromagnetic interference (EMI) from other equipment.

If any shield on a power cable is not grounded, high voltage can be present on
that shield.

Make sure there is a connection to ground for all shield wires inside a power
cable, and for the overall power cable shield.

Failure to observe safety precautions could result in personal injury or damage to
equipment.

Ground Shielded Signal Wires within a Power Cable

Always connect the shield on any signal wire pair routed inside a power cable to
the overall machine ground.

If any shield on a power cable is not grounded, high voltage can be present on that shield.
Make sure there is a connection to ground for all shield wires inside a power cable, and

for the overall power cable shield.
Failure to observe safety precautions could result in personal injury or damage to

equipment.

If you are installing a 2090-XXNPMF-xxSxx, or 2090-CPBM4DF-xxAFxx power
cable, loop the signal wire pairs to the overall cable shield as shown in the
diagram, and then clamp all the shields together in the power cable (chassis)
ground connection on the drive.

Grounding of Signal Wire Shields in a Power Cable

The signal wire pairs within the 2090-XXNPMF-xxSxx, or 2090-CPBM4DF-xxAFxx
power cables often carry a 24V DC brake signal, but also can carry logic signals.
Grounding the shield that surrounds the signal wires dissipates any induced voltage
and reduces the effects of EMI.

Mount the Motor

Follow these steps to mount the motor on a machine.

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 Specifications

Outer surfaces of a motor can reach high temperatures, 125 °C (275 °F) during
operation.

Take precautions to prevent accidental contact with hot surfaces. Consider motor
surface temperature when selecting connections and cables to install on a
motor.

Failure to observe safety precautions could result in personal injury or damage to
equipment.

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 on the machine with its connectors pointing downward.

4. Insert and hand-tighten stainless steel fasteners in each of the four mounting

holes in the motor faceplate.

The mounting hole diameter is specified in the Mounting Dimensions

table.

5. Align the motor on the machine using the mounting pilot hole to verify the

correct alignment.

6. Tighten the stainless steel fasteners within the recommended torque range.

Attach Motor Cables

Follow these steps to attach the feedback, and power/brake cables after the motor
is mounted.

Make sure that cables are installed and restrained to prevent uneven tension or flexing at
the motor-to-cable connections.

Excessive and uneven lateral force at the motor connectors can result in the connector’s
environmental seal opening and closing as the cable flexes.

Failure to observe safety precautions could result in damage to the motor and its
components.

1. Form a drip loop in the cable before attaching it.

A drip loop creates a low spot in the cable. Gravity causes any liquid to flow
to the low spot and away from the connectors, thereby reducing the
potential for any liquid to enter the connector.

2. If you use a cable with a quick-lock plug, remove the O-ring on the

feedback or power/brake connector.

Only threaded cable plugs require the O-ring on the connector. The O-ring
dampens the effects of vibration at the cable-to-motor connection and
creates a more secure connection for a threaded plug. O-rings interior to the
cable plug provide complete environmental sealing for a cable with a
quick-lock plug or a cable with a threaded plug.

Cables requiring O-rings include power cable 2090-XXNPMF-xxSxx or
2090-CPxM4DF-xxAFxx, and feedback cable 2090-XXNFMF-Sxx or
2090-CFBM4DF-CDAFxx.

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.

The motor orientation shown is used to clearly show the alignment marker on
each cable socket.

The recommended motor orientation when installed positions the connectors at
the bottom of the motor.

4. Hand tighten the collar on the plug to fully seat it on the connector.

• Threaded plug requires five to six revolutions.

• Quick-lock plug requires 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.

Keyed connectors and cable plugs must properly align and be hand-tightened the
recommended number of turns.

Improper alignment is indicated by the need for excessive force, such as the use
of tools, to fully seat a plug.

Failure to observe safety precautions could result in damage to the motor and
cable, and their components.

Accessory Kits

Factory available accessories for MP-Series Food Grade motors are described
below.

Motor Cables

Factory manufactured feedback and power cables are available in standard cable
lengths. They provide environmental sealing for IP66 and IP67 ratings and proper
shield termination. For a complete listing of available cables refer to your drive
manual, contact your nearest Rockwell Automation sales office, or access the
information from the references in Additional Resources

.

Refer to the Kinetix Motion Control Selection Guide, publication GMC-SG001

, for

information on feedback, power, and brake cables or connector kits.

Shaft Seals

A shaft seal provides a barrier to moisture and particle entering the motor bearings.

Motors are shipped with a polytetrafluoroethylene (PTFE) shaft seal installed.
Catalog numbers and dimensions for replacement shaft seals are listed in the table.

Shaft Key

Shaft keys are constructed of 300-series stainless steel. The specified tolerance
provides an interference fit (slightly larger than the opening) for a secure and rigid
connection.

Damage can occur to the motor bearings and the feedback device if sharp impact is
applied to the shaft during installation of couplings and pulleys, or a shaft key. Damage
to the feedback device can result by applying leverage from the motor mounting face to
remove devices mounted on the motor shaft.

Failure to observe safety precautions could result in damage to the motor and its
components.

Follow these steps to install a shaft key.

1. Remove the shaft key, if present, using one of these methods:

• Lift the key by grasping it with a plier or similar tool.

• Lever the key with a flat blade screwdriver inserted between the key and
the bottom of the slot.

2. Install a shaft key by performing this procedure.

a. Verify the replacement key matches the keyway in the shaft and the

mating mechanical connection (coupling or pulley).

b. Align the front of the key with the front of the motor shaft.

This prevents interference with the key by the end-of-cut radius.

c. Support the underside of the shaft with a fixture, and use a device to

apply a controlled force that presses the key into the keyway.

Sealing Air Pressure Kit

A sealing air pressure kit (catalog number MPF-7-AIR-PURGE) is available for field
installation on an M23 feedback connector. Positive air pressure supplied through
this kit provides an additional level of protection for the motor against the ingress
of foreign substances and moisture.

The kit replaces the M23 feedback connector cap, provides a replacement O-ring,
and includes installation instructions.

When designing you motion system, consider the following guidelines when
installing a sealing air pressure kit:

• Plastic air tubing should be 4 mm (5/32 in.) OD Teflon FEP tubing.

• Air supplied to the motor should not exceed 0.1 bar (1.45 psi).

Excessive air pressure and improper filtering of air can result in damage to the motor.
Air supplied to the motor must be clean, dry, and of instrument quality. Maximum air

pressure should be 0.1 bar (1.45 psi).
Failure to observe safety precautions could result in personal injury or damage to

equipment.
