Prolonging Linear Thruster Life
Thoughtful design and proper maintenance can increase the life of a linear thruster. Follow these
guidelines to maximize the life of a linear thruster especially within a food processing
environment:
•
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, slider,
and their junctions from contamination by foreign matter or fluids.
•
Inspect the bearings and strip cover, if equipped, 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 linear thruster
performance. Effective techniques to counter EMI include filtering the AC power by 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.
•
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 System Design for Control of Electrical Noise Reference Manual, publication
, for additional information on reducing the effects of EMI.
Install the Linear Thruster
The installation must comply with all local and national safety and electrical codes and use of
equipment and installation practices that promote electromagnetic compatibility and safety.
Only qualified service personnel may install or service a linear thruster.
ATTENTION:
Do not loosen the shipping and handling set screw until the linear thruster is
installed in its application.
ATTENTION:
Install linear thruster to avoid interference with buildings, structures, utilities other
machines and equipment may create a trapping hazard or pinch points.
