4 MP-Series Medium Inertia Servo Motor Installation Instructions

Before You Begin

Remove all packing material 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, and mounting pilot for damage.

3.

Notify the carrier of any shipping damage immediately.

ATTENTION: Do not attempt to open or modify this motor beyond changing the connector orientation as described in Build and Route Cables on page 6 .

An authorized Allen-Bradley repair center must service this item. Refer to

Rockwell Automation Support for assistance to locate the nearest repair center.

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

Using Shaft Seals

You can install a seal on the motor shaft to protect the front bearing from fluids or fine dust that could contaminate the motor bearing and reduce its lifetime. The International Protection (IP) rating for the motor may require the use of shaft seals, connectors, and cables that provide an environmental seal equal to or exceeding the rating:

•

Refer to Specifications on page 22 for a brief description of IP ratings for this motor.

•

Refer to Shaft Seals on page 19 to find the catalog numbers of seal kits for your motor.

•

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.

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:

•

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

•

If design requirements permit, provide shields that protect the motor housing, shaft, seals, and their junctions from contamination by foreign matter or fluids.

•

Replace the shaft seal at or before its expected lifetime of 12 months.

Refer to Shaft Seals on page 19 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 motor is a spring-set holding brake that releases when voltage is applied to its 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.

Publication MPM-IN001C-EN-P - February 2011

MP-Series Medium Inertia Servo Motor Installation Instructions 5

If system main power fails, holding brakes can withstand occasional use as stopping brakes. However, this creates mechanical backlash that 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 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 an improperly tuned servo system oscillating the shaft.

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 on page 19 for guidelines to achieve 20,000 hours of motor bearing life.

ATTENTION: 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.

A shaft key provides a rigid mechanical connection with the potential for self-alignment when the key is properly installed. These sections provide additional information:

•

Refer to Product Dimensions on page 15 for information about the key and keyway.

•

Refer to Shaft Key on page 20 for information about removing and install a shaft key.

6 MP-Series Medium Inertia Servo Motor Installation Instructions

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 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 the 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 performance.

Install cables as described in these guidelines:

•

Keep wire lengths as short as physically 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 electromagnetic interference (EMI) from other equipment.

BURN HAZARD: Do not tightly gather or coil the excess length of a power cable.

Heat is generated within a cable whenever power is applied. Always position a power cable so it may freely dissipate any heat.

A power cable should not be coiled, except for temporary use when building or testing a machine. If you temporarily coil a power cable, you must also derate the cable to meet local code or follow a authoritative directive, such as Engineering

Section 310.15(C) of the NEC Handbook.

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

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-CPBM7DFxx AA xx or 2090-XXNPMFxx S xx power cable, loop the signal wire pair to the overall cable shield as shown in the diagram, and clamp all of the shields together in the power-cable (chassis) ground connection on the drive.

Field Modified

SHOCK HAZARD: 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.

Signal Wire Shield Contacts Overall Power

Cable Shield

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

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

• The 2090-CPBM7DFxx AF xx cable (shown) contains one signal wire pair.

• The 2090-XXNPMFxx S xx cable contains two signal wire pairs.

The additional signal wire pair within the 2090-XXNPMFxx S xx power cable often carries a

24V DC brake signal, but also can carry a logic signal. Grounding the shield that surrounds the signal wires reduces any voltage inductance and the effects of EMI.

Change Connector Orientation

You can rotate the connector housings up to 180°.

This lets you move the connector to a position that best protects the connection from possible environmental contaminates while providing cable access.

ATTENTION: 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 appropriate IP rating as outlined in

Specifications on page 22 .

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

IMPORTANT Do not use tools, such as pliers or vise-grips, to assist you in rotating either a feedback or power/brake connector.

Only apply force to the connector. Do not apply force to or pull on the cable.

Follow these steps to rotate either a feedback or power/brake 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.

ATTENTION: Apply force only to the motor connector and cable plug. Do not apply force to the cable extending from the cable plug. Do not use tools, for example pliers or vise-grips, to assist with the rotation of the connector.

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

MP-Series Medium Inertia Servo Motor Installation Instructions 9

Install the Motor

All 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.

Disassembled equipment must 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.

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.

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

Verify Connector O-ring and Backshell Seal

An o-ring on the feedback connector, and a backshell seal on the feedback and power/brake connectors are necessary to achieve the maximum environmental rating. Verify the seal and o-rings are installed as described.

Location Verify

Groove Reserved for

SpeedTec Plug O-ring

•

An o-ring is mounted on the external surface of the feedback connector and the power/brake connector.

•

The o-ring is not damaged, not twisted, and rests in the groove near the rear of the connector.

•

If using a feedback cable with a SpeedTec plug, the o-ring must be removed.

Backshell Seal Inside

Feedback and

Power/Brake

Connector Housing

•

A backshell seal covers the joint inside the feedback and power/brake housings. It seals the joint between the backshell and the housing of the connector.

•

The backshell seal is not damaged, and it is fully seated against the face of the backshell.

10 MP-Series Medium Inertia Servo Motor Installation Instructions

Mount the Motor

Follow these steps to mount the motor on a machine.

1.

Provide sufficient clearance, heatsink mass, and cooling air so the motor 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. Keep heat producing devices away from the motor. Heatsink requirements are listed in a footnote to the Specifications on page 22 .

BURN HAZARD

BURN HAZARD: 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 on page 17 .

3.

Position the motor on the machine with its connectors pointing downward.

4.

Insert and hand-tighten the fasteners in each of the four mounting holes in the motor faceplate.

The mounting hole diameter is specified in the Product Dimensions on page 15 table.

5.

Align the motor on the machine by using the pilot hole for alignment.

6.

Tighten the fasteners within the recommended torque range.

Cat. No. Torque Range

MPMx 115 x 0.8…1.0 N•m

MPMx 130 x

MPMx 165 x 4…10 N•m

MPMx 215 x 8…20 N•m

7.

Rotate the shaft to verify for electrical phasing and encoder alignment.

The index pulse occurs on a single-turn encoder when the shaft key is aligned with the connectors. Refer to Product Dimensions on page 15 for a visual reference of this alignment.

MP-Series Medium Inertia Servo Motor Installation Instructions 11

Attach Motor Cables

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

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

Excessive and uneven lateral force at the motor connectors can result in the opening-and-closing of the environmental seal 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 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 SpeedTec plug, remove the o-ring on the feedback connector.

SpeedTec plugs require a partial revolution to lock onto the connector, whereas threaded plugs require multiple revolutions to fully lock onto the connector.

The o-ring on the connector dampens the effects of vibration at the cable-to-motor connection and creates a more secure connection for a cable with a threaded plug.

O-rings interior to the cable plug provide complete environmental sealing for a cable with a SpeedTec plug or a cable with a threaded plug.

IMPORTANT Cables requiring o-rings include the 2090-XXNPMFxx S xx and

2090-CP x M4DFxx AF xx power cables, and the 2090-XXNFMF-S xx and

2090-CFBM4DF-CDAF xx feedback cables.

Publication MPM-IN001C-EN-P - February 2011

12 MP-Series Medium Inertia Servo Motor Installation Instructions

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.

IMPORTANT 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

•

SpeedTec plug requires approximately one-quarter of a revolution

TIP A fully-seated threaded plug leaves a small opening, approximately

1…4 mm (0.04…0.16 in.), between the connector and the plug.

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.

ATTENTION: 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.

Shaft Key

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

ATTENTION: 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 pliers or a similar tool.

•

Lever the key with a 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.

Apply a constant force evenly across the top of the key.

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 a motion system, consider these installation 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).

•

The air fitting extends 26 mm (1.0 in.) from the M23 connector when installed.

ATTENTION: 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.
