Motor Installation
Observe the following installation guidelines and those in the Product Notice:
WARNING: Motors and linkages must be securely mounted for a system
! to be operational. Disassembled equipment should be appropriately iden-
tified (tagged-out) and access to electrical power restricted (locked-out).
Failure to observe these safety procedures could result in personal injury
and damage to equipment.
1. Do not run motors that are not properly mounted. Attach all power and data cables after the
motor is mounted.
2. Mount motors with connectors pointing downward and use a drip loop in the cable to keep liq-
uids flowing away from the connectors.
3. Consider motor case temperature if necessary to safeguard operator and maintenance staff.
Maximum case temperature is approximately 100°C (212°F) for a motor used at continuous rat-
ing in a 40°C ambient temperature.
4. The installer must comply with all local regulations and should use equipment and installation
practices that promote electromagnetic compatibility and safety.
Preventing Electrical Noise
ElectroMagnetic Interference (EMI), commonly called “noise”, may adversely impact motor perfor-
mance by inducing stray signals. Effective techniques to counter EMI include filtering the AC power,
shielding and separating signal carrying lines, and practicing good grounding techniques. Effective
AC power filtering can be achieved through the use of isolated AC power transformers or properly
installed AC line filters. Physically separate signal lines from motor cabling and power wiring; do
not parallel signal wires with motor or power wires or route signal wires over the vent openings of
servo drives. Ground all equipment using a single-point parallel ground system that employs ground
bus bars or straps. If necessary, use electrical noise remediation techniques to mitigate EMI in “noisy”
environments.
Knowledgable cable routing and careful cable construction improves system electromagnetic com-
patibility (EMC). General cable build and installation guidelines include:
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 1 foot minimum for every 30 feet of parallel run.
4. Ground both ends of the encoder cable and twist the signal wire pairs.
5. Use shielded motor cables when necessary to prevent electromagnetic interference (EMI) with
other equipment.
Couplings and Pulleys
Mechanical connections to the motor shaft, such as couplings and pulleys, require a 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 will cause system instability
and may damage the motor shaft and keyway. All connections between the system and the servo
motor shaft must be rigid to achieve acceptable response from the system. Connections should be
periodically inspected to verify the rigidity.
When mounting couplings or pulleys to the motor shaft, ensure that the connections are properly
aligned and that axial and radial loads are within the specifications of the motor. The section “Load
Force Ratings” provides guidelines to achieve 20,000 hours of bearing life. Additional information
about load force ratings, including graphical depiction of varied load ratings and bearing life, is
available for any motor from the Technical Support groups listed on the back cover.
