About the MP-Series Medium Inertia Motors

MP-Series™ medium-inertia (Bulletin MPM) motors feature resolvers and single-turn or
multi-turn high resolution encoders. They are also available with 24V DC holding brakes. These
compact brushless servo motors combine the features of the MP-Series low-inertia motors with a
rotor that is better suited for high-inertia loads.

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:

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

motor.

Rockwell Automation Publication MPM-IN001D-EN-P - January 2014

MP-Series Medium-inertia Servo Motor with 115 mm to 215 mm Frame Size 5

IMPORTANT

• If possible, provide shields that protect the motor housing, shaft seals, and their

junctions from contamination by foreign matter or 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 20 for more information.

• Inspect the motor and seals for damage or wear on a regular basis. If damage or excessive

wear is observed, replace the item.

• 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 ser vo 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 IP65 or IP67 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 to Specifications on page 22 for a brief description of the IP rating for these

MP-Series motors.

• Refer to Shaft Seal Kits on page 20 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

on page 20 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

Rockwell Automation Publication MPM-IN001D-EN-P - January 2014

MP-Series Medium-inertia Servo Motor with 115 mm to 215 mm Frame Size 7

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.

Connect all signal wire shields and the overall power-cable shield to machine ground:

• The 2090-CPBM7DF-xxAFxx cable (shown) contains one signal wire pair.

• The 2090-XXNPMF-xxSxx cable contains two signal wire pairs.

All power and signal wire shields must connect to machine
ground.

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 you are installing a 2090-CPBM7DF-xxAAxx or 2090-XXNPMF-xxSxx
power cable, loop the signal wire pair to the overall cable shield as shown in Grounding of Signal

Wire Shields in a Power Cable on page 8. Then clamp all of 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 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 hardened steel. The installation must comply with all local regulations and use
equipment and installation practices that promote safety and electromagnetic compatibility.

ATTENTION: Unmounted motors, disconnected mechanical couplings, loose shaft keys, and disconnected
cables are dangerous if power is applied.

Lock-out and tag-out disassembled equipment (restrict electrical power).

Rockwell Automation Publication MPM-IN001D-EN-P - January 2014

Before applying power to the motor, remove the shaft key and other mechanical couplings that can be thrown
from the shaft.

ATTENTION: 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.
