About the MP-Series Electric Cylinders
MP-Series electric cylinders feature multi-turn high resolution encoders and are available with
24V DC brakes. The MP-Series motor rotates a ballscrew drive that converts rotary motion into
linear movement. This linear movement results in the piston rod extending and retracting from
the electric cylinder housing.
The MP-A/B xxxxx-x2x electric cylinders are non-braking. When there is no input torque, the
piston rod can be moved freely. You can achieve self-locking of your motion system by using
motors with an integrated brake or with high self-braking torque.
The MP-Series electric cylinders have been designed for exact positioning at high speeds.

Failure to observe these safety precautions could result in personal injury or damage to
equipment.
Planning Your Installation
Refer to the Kinetix® Motion Control Selection Guide, publication GMC-SG001, for the
specifications and additional products referenced in this section:
• This product can be operated in compliance with the relevant safety regulations only if
the maximum loading limits are observed.
12. Only a qualified Allen-Bradley®
ATTENTION: The electric-cylinder is not intended to be used in applications where
side-loading occurs. Loads must be guided and supported. Aligned load with the
line-of-motion of the piston rod.
Side loading will reduce the lifetime of the elec tric-cylinder.
• If you are mounting your electric cylinder in a vertical or sloping position, include safety
measures that will control the workload should the spindle nut fail.
ATTENTION: Uncontrolled moving masses can cause injury or damage to proper ty.
If there is a spindle nut fracture inside the actuator cylinder due to wear, the working
mass will drop down.
Check whether additional external safety measures are required to prevent damage in
the event of a spindle nut fracture.
• Corrosive environments reduce the service life of electric cylinders.
• Depending on the workload, the piston rod will bend. Refer to the piston-rod deflection
specifications for limitations.

• Motor feedback, auxiliary feedback, and I/O connector kits are not included, but can be
purchased separately.
• Factory manufactured feedback and power cables are available in standard cable lengths.
They provide environmental sealing and shield termination. Contact your Allen-Bradley
sales office or refer to the selection guide for cables.
Electric Cylinders with Brake Option
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.
An unpowered electric cylinder will require a brake to maintain its position if the force on the
actuator exceeds the Back Drive Force listed in Kinetix Linear Motion Specifications Technical
Data, publication GMC-TD002.
A brake can be use with the actuator to keep it from backdriving, typically in vertical
applications. A brake may be used for safety reasons or for energy savings allowing the actuator to
hold position when unpowered.
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.

Preventing Electrical Noise
Electromagnetic interference (EMI), commonly called electrical noise, can reduce motor
performance. Effective techniques to counter EMI include filtering the AC power, using
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 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.
Build and Route Cables
Knowledgeable cable routing and careful cable construction improves system electromagnetic
compatibility (EMC).
Follow these steps to build and install cables.
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.
ATTENTION: High voltage can be present on the shield of a power cable if the shield is not
grounded.
Make sure there is a connection to ground for any power cable shield.
Failure to observe these safety precautions could result in personal injury or damage to equipment.

IMPORTANT
Install the Electric Cylinder
The installation must comply with all local regulations and use of equipment and installation
practices that promote electromagnetic compatibility and safety.
ATTENTION: Unmounted electric cylinders, disconnected mechanical couplings, and disconne cted
cables are dangerous if power is applied.
Disassembled equipment should be appropriately identified (tagged-out) and access to electrical
power restricted (locked-out).
Failure to observe these safety precautions could result in personal injury.
ATTENTION: Make sure that cables are installed and restrained to prevent uneven tension or
flexion 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 precautions could result in damage to the electric cylinder motor
and its components.
ATTENTION: Damage may occur to the electric cylinder bearings and the feedback device if a
sharp impact to the piston rod is applied during installation. Do not strike the piston rod with tools
during installation or removal.
Do not attempt to rotate the piston rod during installation. Rotating the piston rod will break the
mechanism that allows the electric cylinder to extend and retract.
Failure to observe these safety precautions could result in damage to the electric cylinder and its
components.
Follow these steps to install the electric cylinder.
1. Provide sufficient clearances in the area of the electric cylinder for it to stay within its
specified operating temperature range.
Refer to Specifications

4. Attach rod-end accessories and the workload.
Be sure the workload center of gravity is centric to the piston rod.
ATTENTION: Damage may occur to the electric cylinder bearings and the feedback
device if sharp impact to the piston rod is applied during installation. Do not strike the
piston rod with tools during installation or removal.
Failure to observe these safety precautions could result in damage to the electric c ylinder
and its components.
Do not twist or rotate the piston rod. If the piston rod is rotated, the absolute position
of the electric cylinder will be lost and the absolute home position must be
re-e stablished.
When fastening a rod-end accessory or workload to the piston rod, use two wrenches.
Use one wrench to tighten the mounting nut or rod-end accessory and the other, on the
piston-rod wrench flats, to counteract the applied torque. Be sure that the torque is not
applied to the piston rod and that the piston rod does not rotate.

Mount the Electric Cylinder
1. Use stainless steel fasteners to mount your electric cylinder to your application.
2. Attach power and feedback cables after the electric cylinder is mounted, and use a drip
loop in the cable to keep liquids away from the connectors.
BURN HAZARD: Outer surfaces of the motor can reach high temperatures, 65 °C
(149 °F), during electric cylinder operation. Take precautions to prevent accidental
contact with hot surfaces. Failure to observe these safety precautions can result in
personal injury.
ATT EN TI ON : Consider electric-cylinder surface temperature when selecting
motor-mating connections and cables. Failure to observe these safety precautions can
result in personal injury or damage to equipment.
ATT EN TI ON : Keyed connectors must be properly aligned and hand-tightened the
