Tip: Teknic recommends mounting the motor such that the USB port and
status LED are visible and accessible when the motor is mounted to the
machine.
• Do not mount ClearPath over a heat source such as a power
supply, spindle drive, etc.
• Do not mount ClearPath in an unventilated enclosure.
• Do allow for at least 1” of space around each ClearPath.
• ClearPath can be fitted with an external accessory fan if desired.
• ClearPath will perform a protective Shutdown when its internal
temperature sensor threshold is exceeded.

While it’s obvious that ClearPath must be connected to a mechanical
system to do useful work, it’s not always clear just how to connect the
motor to the mechanics.
Problems arise when a connecting element (such as a coupling) slips,
exhibits excessive backlash, or can not accommodate typical shaft-to-shaft
misalignments. Ultimately, the choice of shaft interface or coupling
depends on the application, whether a precision positioning stage or a low
speed conveyor.
The shaft interface (coupling, pulley, pinion, etc.) must be securely
clamped to the shaft with minimum backlash (ideally none). This primary
mechanical interface is critical in achieving and maintaining the best
possible performance from a servo motion system.

• Align with care. When connecting two shafts—such as a
motor shaft to a screw shaft—the rotating centers must be
carefully aligned in both the angular and offset sense (including
offsets/adjustments for thermal growth) to achieve the best
possible motion quality and longest motor/bearing life.
Some couplings are more forgiving of misalignment than
others, but in general, misalignment will cause undesired
vibration/noise, shortened bearing life, and even broken motor
