Motor-Related Warnings
Aerotech motors are capable of producing high forces and velocities. Obey all warnings and all
applicable codes and standards when you use or operate a stage or system that incorporates
Aerotech motors.
DANGER: Mechanical Hazard!
Personnel must be made aware of the mechanical hazards during set up or when you
do service to the stage.
lUnintentional manual movement into the stage "end-of-travel" stops, could damage
the stage or undo precision alignments.
lStage movement could create pinch points, entanglement hazards, or rotational
mechanical hazards.
DANGER: Hot Surface Hazard!
lThe stage/motor frame temperature could exceed 70°C in some applications.
lDo not touch the stage/motor frame while it is in operation.
lWait until the stage/motor has cooled before you touch it.
