Installation and Maintenance Guidelines
The guidelines in this section provide you with general information about installing servo
motors. Instructions specific to MPL servo motor installation follow this section.
To Prolong Motor Life
Thoughtful design and proper maintenance can increase the life of a servo motor. The following
are guidelines to maximize the life of a servo motor.
• Always install the motor with any cable entry point positioned underneath the motor
housing, and provide a drip loop in each cable. A drip loop is a downward bend in the
cable that lets water gather and drip off the cable rather than continue to flow along the
cable. These two installation practices greatly reduce the potential for moisture related
problems, and are depicted in the illustration.
Recommended Connector Orientation for Drip Loop
Cable enters beneath the
motor, and drip loop is formed.
• Avoid installing the motor with the shaft pointing upward, even if shaft seal in installed.
This orientation increases the risk of contaminant ingress.
Publication MP-IN015A-EN-P - October 2010
Motor is positioned so
cable enters from above.
Cable lacks drip loop.
MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes 5
• Bearing contamination will shorten the life of a motor. The probability of this occurring
can be significantly reduced by installing a shaft seal. Ingress Protection Codes (IP
Ratings) for various mounting orientations are described in the Specifications section.
– A shaft seal is recommended whenever the motor shaft is exposed to moisture and
other fluids, including lubricating oil from a gearbox, or significant amounts of fine
dust.
– A shaft seal may be unnecessary if the motor shaft area is free of liquids or fine dust
and a lower IP rating will suffice.
• The brake on these motors are a permanent magnet-type holding brake. The brake
releases when voltage is applied. A separate 24V DC power source must be connected
with proper polarity to disengage the brake. This power source may be applied by a servo
motor controller, in addition to manual operator control.
If system main power fails, holding brakes can withstand occasional use as stopping
brakes. However, this is potentially damaging to the system, increases brake wear, and
reduces brake life.
IMPORTANT
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 first, command
the servo drive to 0 rpm, second, verify the motor is at 0 rpm, third, engage the
brake, and finally, disable the drive.
Disabling the drive also removes the potential for brake wear caused by a badly
tuned servo system oscillating the shaft.
Mount the Motor
All MPL motors include a mounting pilot for aligning the motor on a machine. Preferred
fasteners are stainless steel. The installation must comply with all local regulations and use of
equipment and installation practices that promote electromagnetic compatibility and safety.
ATTENTION: 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 that could be thrown from the shaft.
Failure to observe these safety procedures could result in personal injury.
The dimensions and dimensional symbols for the different frame sizes and stack lengths in the
MPL motors are referenced in the MP-Series Low-inertia Servo Motors Dimensions drawing
and tables.

6 MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes
Mechanical Connections
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 will
cause system instability and may damage the motor shaft. All connections between the machine
and the motor shaft must be rigid to achieve acceptable system response. Periodically inspect
connections to verify their rigidity.
ATTENTION: Do not strike the shaft, key, couplings, or pulleys with tools
during installation or removal.
Damage may occur to the motor bearings and the feedback device if sharp
impact to the shaft is applied during installation of couplings and pulleys, or a
shaft key. Damage to the feedback device also may result by applying leverage
from the faceplate to remove devices mounted on the motor shaft.
Apply a constant pressure, with a wheel puller for example, to the user end of
the shaft to remove a friction fit or a stuck device.
Failure to observe these safety procedures could result in damage to the motor
and its components.
When mounting couplings or pulleys to the shaft, verify that the connections are properly
aligned and that axial and radial loads are within the specifications of the motor.
Refer toLoad Force Capacities
motor bearing life.
A shaft key provides a rigid mechanical connection with the potential for self-alignment, but the
key must be properly installed in the keyway. Refer to MP-Series Low-inertia Servo Motors
Dimensions on page 13 for dimensional information about the key and shaft keyway.
Instructions for removing or installing a shaft key are provided in Shaft Key Removal and
Installation on page 17
on page 16 for guidelines on how to achieve 20,000 hours of
.
Connector Orientation
The housings for the feedback and power and brake connectors can be rotated once up to 180
degrees. This allows either connector to face down if the motor is installed in a vertical
application, rearward if connector access is restricted in a horizontal application, or to the side of
the motor.
ATTENTION: Connectors are designed to be rotated into a fixed position
during installation of the motor, and remain in that position without further
adjustment. Strictly limit the applied forces and the number of times the
connector is rotated to be sure that connectors meet the requirements of IP66.
Failure to observe these safety procedures could result in damage to the motor
and its components.
Publication MP-IN015A-EN-P - October 2010
MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes 7
Rotate the connectors as follows.
1. Mount and fully seat a mating cable on the connector.
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. No tools (for example, pliers
and vise-grips) should be used to assist with the rotation of the connector.
Interconnect Cables
Knowledgeable cable routing improves system electromagnetic compatibility (EMC). Refer
to Shield the Power Cable on page 8 for suggested grounding techniques.
To install cables properly, observe these guidelines.
• Do not connect feedback cable or power and brake cable while power is applied.
ATTENTION: Do not connect or disconnect the motor feedback cable, or the
power and brake cable while power is applied to them.
Inadvertent pin connections may result in unexpected motion or result in
irreversible damage to the components.
• Keep wire lengths as short as physically possible.
• Separate cables by 0.3 m (1 ft) minimum for every 9 m (30 ft) of parallel run.
• Route signa l cables that transmit encoder, seria l, or ana log data at low volta ges away from
the motor and power wiring.
• Ground both ends of the cable shield and twist the signal wire pairs to prevent
electromagnetic interference from other equipment.
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.
Failure to observe these safety procedures could result in personal injury or
damage to equipment.
Electrical Noise
Electromagnetic interference (EMI), commonly called noise, may adversely impact 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. Effective AC power filtering can be achieved by using isolated AC power
transformers or properly installed AC line filters.
Publication MP-IN015A-EN-P - October 2010
8 MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes
To reduce EMI, observe these guidelines:
• Physically separate signal lines from motor cabling and power wiring. Do not route
signal wires with motor and power wires, and do not route signal wires over the vent
openings of servo drives or other electrical power sources.
• 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.
Shield the Power Cable
Shield the power cable as follows.
1. Verify the separate signal wire shield connects to the overall chassis ground by looping
back each of the signal wire pairs as shown in the diagram.
2. Clamp all three shields together at the power cable (chassis) ground connection on the
drive.
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.
Failure to observe these safety procedures could result in personal injury or
damage to equipment.
Power Cable Shielding
Cable is factory supplied as follows.
Cable can be field modified as follows.

Brake Control and Power Regulation
The DC power source for a permanent magnet brake, such as that on the MP-Series servo motor
with 75 mm (2.95 in.) or smaller frame, requires a DC power supply with low ripple voltage.
A motor brake requires relay contacts to open and remove power to the brake coil. Removing
power causes the brake to mechanically engage, but it also may cause electrical arcing to occur at
the contacts until the residual brake power sufficiently dissipates. A customer supplied diode is
recommended to prevent electrical arcing at the brake relay contacts. Substituting a metal oxide
varistor (MOV) for the diode can reduce the time to mechanically engage the brake. The
following diagram shows typical customer supplied components for brake control, including an
arc suppressing diode or MOV.

Diode or MOV Arc Suppressor
The Kinetix 6000 and Kinetix 7000 drives from Rockwell Automation have a brake control relay
that includes a MOV arc suppressor. Customer supplied arc suppression is not required in this
case, unless power consumption by the brake requires an external brake relay.
Shaft Seals
An optional shaft seal may be 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
rating for the motor depends on the usage of shaft seals and environmentally sealed
connectors/cables.

Follow these steps to install an MPL motor.
ATTENTION: Do not strike the shaft, couplings, or pulleys with tools during
installation or removal.
Damage may occur to the motor bearings and the feedback device if sharp
impact to the shaft is applied during installation of couplings and pulleys.
Failure to observe these safety procedures could result in damage to the motor
and its components.
1. Allow sufficient clearances in the area of the motor for it to stay within its specified
operating temperature range.
Refer toSpecifications on page 19
Do not install the motor in an area with restricted airflow. Keep other heat producing
devices away from the motor.
To obtain the specified motor thermal rating , mount the motor so the heat dissipation is
at a minimum equivalent to the following surface.
For Motor Aluminum Heatsink Dimensions, Approx.
MPL-x15xx 203.2 x 203.2 x 6.35 mm (8 x 8 x 0.25 in.)
MPL-x2xx 254.0 x 254.0 x 6.35 mm (10 x 10 x 0.25 in.)
for the operating temperature range.
ATTENTION: Outer surfaces of the motor can reach high temperatures, 125 °C
(257 °F), during motor operation.

4. Form a drip loop in the cables directly before each cable attaches to the motor.
Refer toRecommended Connector Orientation for Drip Loop
example.
ATTENTION: Be sure 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.
5. Attach the feedback and the combination power and brake cables to the motor.
ATTENTION: Do not connect or disconnect the motor feedback cable, or the
power and brake cable while power is applied to them.
Inadvertent pin connections may result in unexpected motion or result in
irreversible damage to the components.
a. Carefully align each cable connector with the respective motor connector as shown
in Motor Connector Alignment
b. Do not apply excessive force when mating the cable and motor connectors. If the
connectors do not go together with light hand force, realign and try again.
6. Hand-tighten each collar as follows.
on page 12.
on page 4 for a visual
• One-quarter turn for a SpeedTec connector
• Five to six turns for a threaded connector
ATTENTION: Keyed connectors must be properly aligned and 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 connectors.
Connectors must be fully tightened for connector seals to be effective.
Failure to observe these safety procedures could result in damage to the motor,
cables, and connector components.

Troubleshooting and Maintenance
Standard troubleshooting and maintenance for this motor includes the following activities.
ATTENTION: Do not strike the shaft, key, couplings, or pulleys with tools
during installation or removal of any device.
Damage may occur to the motor bearings and the feedback device if sharp
impact to the shaft is applied during installation of couplings and pulleys, or
a shaft key. Damage to the feedback device also may result by applying
leverage from the faceplate 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 any friction fit or stuck device from the motor shaft.
Failure to observe these safety procedures could result in damage to the
motor and its components.
Shaft Key Removal and Installation
Shaft keys are toleranced for an interference fit (slightly larger than the opening) to provide a
secure and rigid fit for the mating connection.
To Remove a Shaft Key
Lif t the key by grasping it with a plier or similar tool, or lever the ke y with a flat-blade screwdriver
inserted between the key and the slot.
To Install a Shaft Key
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. Support the motor shaft to prevent movement and to avoid motor bearing damage.
3.
Align the front of the key with the front of the motor shaft. This prevents a radiused
end-of-cut at the motor end of the keyway from interfering with correct seating of the key.
4. Apply a constant force across the exposed surface of the key with a controlled press
device (for example, a screw clamp) to push the key into the shaft.
Shaft Key Installation
Apply a constant force evenly
across the top of the key.

Motor Cables and Accessory Kits
Accessories available from the factory include motor cables and shaft seals.
Motor Cables
Factory manufactured feedback and power cables are available in standard cable lengths. They
provide the sealing needed to achieve environmental ratings and shield termination.
Refer to the Kinetix Motion Control Selection Guide, publication GMC-SG001
numbers of cables appropriate for these motors.
Shaft Seals
Shaft seals provide environmental sealing of MPL motors. Shaft seals provide an additional
barrier to moisture and particle intrusion to the motor bearings. Motors are shipped without a
shaft seal, but this option is easily installed or replaced in the field.
MPL shaft seals have a Nitrile contact surface. Shaft seals require a lubricant provided in the kit.
