Prolonging Motor Life
Thoughtful design and proper maintenance can increase the life of this motor.
Follow these guidelines to maximize the life of the 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 bore, seals, and their junctions from contamination by
foreign matter or fluids.
• Inspect the motor for damage or wear on a regular basis. If damage or
excessive wear is observed, replace the item.
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 the System Design for Control of Electrical Noise Reference Manual,
publication GMC-RM001
, for additional information on reducing the effects of EMI.

ATTENTION
Build and Route Cables
Knowledgeable cable routing and careful cable construction improves system
performance.
Follow these guidelines to build and install cables:
• Keep wire lengths as short as physically possible.
• Route noise sensitive wiring (encoder, serial, 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.
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 an 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 the Shielded Signal Wires within a Power Cable
Always ground the shield on any signal wires inside a power cable. Connecting this
shield to chassis ground reduces the potential for voltage inductance and EMI.
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.
Follow these steps to ground the shield wire on a 2090-CPBM7DF-xxAFxx or
2090-XXNPMF-xxSxx power cable.
1. Loop the signal wire pair to the overall cable shield as shown in the
diagram.
• Cable 2090-CPBM7DF-xxAFxx (shown) contains one signal wire pair.
• Cable 2090-XXNPMF-xxSxx contains two signal wire pairs.
2. Clamp all signal wire shields and the overall power-cable shield in the
power cable (chassis) ground clamp on the drive.

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.
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
that could be thrown by the motor.
Failure to observe these safety precautions could result in personal injury.
Servo drive power must be turned off before connecting or disconnecting the cables to the
motor, and if a cable is left disconnected at the motor end.
Arcing or unexpected motion could occur if the feedback, power, or brake cables are
connected or disconnected while power is applied to the servo drive.
Failure to observe these safety procedures could result in personal injury or damage to the
motor and equipment.

Align the flat surfaces
before securing connection.
Attach the Motor Cables
Follow these steps to attach the feedback and power/brake cables after the motor is
mounted.
Make sure that cables are installed and restrained to prevent uneven tension or flexing at
the motor-to-cable connections.
Excessive and uneven lateral force at the motor connectors can result in the connector’s
environmental seal opening and closing 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 low spot and away from the connectors, thereby reducing the
potential for any liquid to enter the connector.
2. Determine if you should remove the O-ring from the motor connectors.
• Threaded plugs (power or feedback) require an O-ring.
• SpeedTec plugs (power or feedback) do not require an O-ring.
The O-ring on the motor connector dampens the effects of vibration at the
cable-to-motor connection. This creates a more secure connection for a
cable with a threaded plug. O-rings interior to the threaded and SpeedTec
plug provide complete environmental sealing for the connection.
The 2090-XXNPMF-xxSxx power cable and the 2090-XXNFMF-Sxx feedback cable require
an O-ring on the motor connector.

3. Carefully align the flat surface on the feedback or power/brake cable plug
with the flat surface on the motor connector.
The connector orientation shown is used to clearly show the alignment marker on each
cable socket.
The recommended 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.
• The threaded plug requires five to six revolutions.
• The SpeedTec plug requires approximately one-quarter of a revolution.
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.
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.

3. Secure the black cap screw in hole A by tightening it to 3.4 N•m (2.5 ft•lb).
Remove the Motor From the Machine
Follow these steps to remove the motor and to cover the opening before storing it.
1. Remove the fastener from each of the four mounting holes in the motor
faceplate.
2. Slide the motor off the machine shaft.
Notches in the motor-mounting surfaces provide a means to gently pry the motor loose
from the machine.
A flat-bladed pry bar may be used to loosen the motor.
Cover the Mounting End of the Motor
Seal the opening in the motor by performing the following steps.
1. Insert the protective paper sleeving around the rotor.
2. Cover the opening at the mounting end of the motor with the cardboard
cover that came with the motor.
Magnetized material within the motor is exposed whenever the protective cover is
removed and before the motor is mounted.
Accidental entry of foreign material can harm motor performance.
Always cover the mounting end of motor immediately after removing the motor or its
protective cover. This will greatly reduce the possibility of magnetic or non-magnetic
particles accidentally entering the motor.
