Install the Motor
MP-Series 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.
Mount the Motor
Follow these steps to mount the motor.
1. Provide sufficient clearance, heatsink mass, and air flow for the motor so it 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, and keep other
heat producing devices away from the motor. Heatsink requirements are listed in a
footnote to the
Motor Cables and Accessory Kits
table.
2. Verify the axial and radial shaft loads of your application do not exceed those listed in the
3. Position the motor with the cable connections beneath the motor.

cable positioning.
4. Properly mount and align the motor.
The index pulse occurs on a single-turn encoder when the shaft key is aligned with the
connectors. Refer to
for a visual reference of this
alignment.
ATTENTION: Unmounted motors, disconnected mechanical couplings, loose shaft keys, and disconnected
cables are dangerous if power is applied.
Lock-out and tag-out disassembled equipment (restrict electrical power).
Before applying power to the motor, remove the shaft key and other mechanical couplings that can be thrown
from the shaft.
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.
ATTENTION: Damage can occur to the motor bearings and the feedback device if sharp impact to the shaft is
applied during installation of couplings and pulleys.
Do not strike the shaft, couplings, or pulleys with tools during installation or removal.
ATTENTION: Outer surfaces of the motor can reach high temperatures of 125 °C (275 °F) during
operation.
Take precautions to prevent accidental contact with hot surfaces. Consider motor surface temperature
when selecting motor mating connections and cables.
