Chapter 1 Safety Considerations
Vertical or Incline
Installation A linear motor driven system mounted vertically or on an incline will not
maintain position when the power is removed. Under the influence of gravity, the
motion platform and its payload will fall to the low end of travel. Design
engineers should allow for this by designing in controlled power-down circuits or
mechanical controls to prevent the linear motor driven system and its payload
from being damaged when the power fails.
ATTENTION: Linear motors are capable of high accelerations, sudden
and fast motion. Rockwell Automation is not responsible for misuse, or
improper implementation of this equipment.
ATTENTION: Linear motor driven systems must have end of travel
bumpers. They must be designed to take a large impact from uncontrolled
motion. The payload must be secured to the system such that it will not
sheer off in the event of an impact in excess of the bumper ratings.
ATTENTION: The Hall effect module contains an electrostatic discharge
(ESD) sensitive device. You are required to follow static-control
precautions when you install, test, service, or repair this assembly. If you
do not follow ESD control precautions, components can be damaged. If
you are not familiar with static control precautions, refer to Guarding
Against Electrostatic Damage, publication
8000-4.5.2 , or any other
applicable ESD awareness handbook.
BURN HAZARD: When the linear motors are running at their maximum
rating, the temperature of attached heat sinks can reach 100 ºC (212 ºF).
SHOCK HAZARD: An assembled linear motor will generate power if the
coil or magnet track is moved. Unterminated power cables present an
electrical shock hazard. Never handle flying leads or touch power pins
while moving the motor.
