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 within a food processing environment.
• Always provide a drip loop in each cable to carry liquids away from the connection to the motor.
• Avoid spraying liquids under high pressure directly on the junction of the motor shaft, housing, connectors, and the enclosure joints. Fluids under high pressure, when forced around worn seals, can contaminate the motor bearings and significantly shorten the life of a servo motor.
• If design requirements permit, provide shields that protect the motor housing, shaft, seals and their junctions from product contamination, caustic agents, and high pressure fluids.
• Replace the shaft seal at or before its expected lifetime of 12 months. Refer to Shaft Seals
for more information on shaft seals.

IMPORTANT
• Inspect the motor and seals for damage or wear on a regular basis. If damage or excessive wear is observed, replace the item.
• If desired, you may seal the motor front flange to the driven equipment by applying a bead of food grade RTV around the periphery of the joint between the motor and the machine surfaces. Use of a gasket or RTV on the mating surfaces is not recommended, as this can cause misalignment of the shaft and result in damage to the motor and/or driven equipment.
• 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.
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.
Using Shaft Seals
A seal is 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/IP67 rating for the motor requires the use of shaft seals, connectors, and cables that provide an environmental seal equal to or exceeding the rating.
• Refer to Specifications
• Refer to Shaft Seals
• 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.

ATTENTION
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 hours of motor bearing life.
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 Mounting Dimensions

keyway.
• Refer to Shaft Key

shaft key.

Preventing Electrical Noise
ElectroMagnetic Interference (EMI), commonly called electrical noise, can reduce motor performance. Effective techniques to counter EMI include filtering the AC power, use of 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 System Design for Control of Electrical Noise Reference Manual, publication GMC-RM001
, for additional information on reducing the effects of EMI.

Install the Motor
All motors include a mounting pilot for aligning the motor on the machine. Preferred fasteners are stainless steel. The installation must comply with all local regulations and use equipment and installation practices that promote safety and electromagnetic compatibility.
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 safety precautions could result in personal injury.
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 result in the environmental seal opening and closing 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
O-rings on the feedback and motor/brake connectors secure cable plugs, and a backshell seal on the feedback connector is necessary to achieve the maximum environmental rating. Verify the seal and O-rings are installed as described.
Location Verify
An O-ring is mounted on the external surface of
both the power/brake connector and the feedback connector.
The O-ring is undamaged, not twisted, and rests
in the groove as shown in the illustration.
A backshell seal covers the joint between the
backshell and the connector housing.
Publication MP-IN004D-EN-P — April 2009
The backshell seal is undamaged, and it is fully
seated against the face of the backshell.

ATTENTION
Change Connector Orientation
You may rotate the connector housing up to 180 degrees. This lets you adjust the connector to a position that best protects the connection from possible environmental contaminates while providing cable access.
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 requirements of IP66 and IP67.
Failure to observe safety precautions could result in damage to the motor and its components.
Do not use tools, such as pliers or vise-grips, to assist you in rotating the connector. Only apply force to the connector. Do not apply force to or pull on the cable.
The circular DIN connector housing can be rotated up to 180° in either direction.
Follow these steps to rotate a DIN 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.
Apply force only to the motor connector and cable plug. Do not apply force to the cable extending from the cable plug. No tools, for example pliers or vise-grips, should be used to assist with the rotation of the connector.
Failure to observe safety precautions could result in damage to the motor and its components.
3. Repeat these steps for the other connector.
