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 devise. 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 sink can reach 100 ºC (212 ºF).
SHOCK HAZARD
An assembled linear motor will generate power if the coil or
magnet channel is moved. Un-terminated power cables present
an electrical shock hazard. Never handle flying leads or touch
power pins while moving the motor.
