About the MP-Series Motors

MP-Series low-inertia motors feature single-turn or multi-turn high resolution
encoders, and are available with 24V dc brakes. These compact brushless servo
motors meet the demanding requirements of high-performance motion systems.

Before You Begin

The customer is responsible for inspecting the equipment before accepting the
shipment from the freight company. Check the item(s) you receive against your
purchase order. Notify the carrier of any shipping damage or missing items
immediately.

Store or operate your motor in a clean and dry location within the following
environmental conditions.

Before You Install the Motor

Perform the inspection steps and review the guidelines for shaft seals, couplings
and pulleys, and electrical noise prevention.

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.

Do not attempt to open and modify the motor beyond changing the connector orientation
as described on page 7
motor.

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

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 use of a shaft
seal and environmentally sealed connectors/cables. The additional seal is not

ATTENTION

recommended in applications where the motor shaft area is free of liquids or fine
dust and a lower rating will suffice.

• Refer to Environmental Ratings

for a brief description of the IP rating for

these MP-Series motors.

• Refer to Shaft Seal Kits

to find the catalog numbers of seal kits available for

your motor.

• Refer to Kinetix Motion Control Selection Guide, publication GMC-SG00

1 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 will cause system instability and may
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, ensure that the
connections are properly aligned and that axial and radial loads are within the
specifications of the motor. Refer to Motor Load Force Ratings

for guidelines to

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. Damage to the feedback
device may 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 applying pressure from 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.

Preventing 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.

ATTENTION

Avoid the effects of EMI by following these guidelines.

• Physically separate signal lines from motor cabling and power wiring. Do
not route signal wires 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 by

improving the system level electromagnetic compatibility (EMC).

Building and Installing Cables

Knowledgeable cable routing and careful cable construction improves system
electromagnetic compatibility (EMC).

To build and install cables, perform the following steps.

1. Keep wire lengths as short as physically possible.

2. Route signal cables (encoder, serial, analog) away from motor and 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.

High voltage can be present on the shield of a power cable, if the shield is not grounded.
Ensure there is a connection to ground for any power cable shield.
Failure to observe these safety procedures could result in personal injury or damage to

equipment.

ATTENTION

Install the Motor

All 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.

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 these safety procedures could result in personal injury.

Ensure 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.

Changing 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.

The sections below describe acceptable methods for rotating the connector
orientation for these connector styles.

ATTENTION

Reversible Connector Facing the Shaft (MPL-xxxxx-xx2xxx)

This connector housing can be reversed to face down when the motor is installed
in a vertical application, or rearward if connector access is restricted in a horizontal
application. Perform these steps to remount the connector housing.

1. Remove the three connector housing screws from the motor.

2. Rotate connector housing 180 degrees. If binding of the wire bundles

prevents rotation of the connector, you can gain access to the internal motor
wiring by following these steps.

a. Remove the four screws from the rear cover of the motor.
b. Carefully reposition the wires around the perimeter of the motor

feedback device located under the rear cover.

c. Be sure that the wires are not close to any rotating parts.

Do not loosen or remove the motor feedback device (encoder) mounting screws while
repositioning the connector wires.

Encoder alignment is a critical adjustment that can only be performed in the factory.
Misadjustment can render the motor inoperable or degrade motor performance, and voids
the motor warranty.

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

3. Re-install the connector housing and torque the three screws to

0.8…1.0 N•m (7…9 lb•in.) after verifying that gaskets are properly
positioned, and that no wires are pinched under the connector housing.

Exercise caution to prevent damaging the screw holes when reinserting the self-tapping
screws holding the connector housing and rear cover.

Excessive force may strip the threads within the screw holes and prevent proper sealing of
the motor. Ensure that the specified torque values are not exceeded.

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

4. Re-install the four rear cover screws and torque them to 0.8…1.0 N•m

(7…9 lb•in) after ensuring that the rear cover O-ring is properly positioned
onto the rear cover circular pilot surface.
