Safety Considerations Chapter 1
Operational Guidelines
Please read and follow the guidelines shown here to safely operate the linear
motor created from these linear motor components.
ATTENTION: Observe maximum safe speed. Linear motors are capable
of very high forces, accelerations, and speeds. The maximum obtainable
acceleration and speed is based on the drive output (bus voltage and
current settings). The allowable maximum speed is application specific
and partly based on the linear motion mechanics supplied by others.
ATTENTION: Moving parts can cause injury. Before operating the linear
motor, make sure all components are secure and magnet mounting
hardware is below the magnet surface. Remove all unused parts from the
motor travel assembly to prevent them from jamming in the motor air gap
and damaging the coil or flying off and causing bodily injury.
IMPORTANT
You are responsible for making sure the servo control system safely
controls the linear motor with regards to maximum safe force,
acceleration, and speed, including runaway conditions.
A runaway condition can be caused by incorrect motor, hall effect, and
position feedback wiring resulting in violent uncontrolled motion.
ATTENTION: Keep away from the line of motor travel at all times.
Always have bumpers in place and securely fastened before applying
power to your linear motor.
ATTENTION: High voltage can kill. Do not operate with exposed wires.
Do not go near electrically live parts.
ATTENTION: Large Position Error Tolerances, such as those calculated by
the Auto Tune function in RSLogix 5000 programming software, or when
configuring a new axis with RSLogix 5000 software, can lead to
undetected and repetitive high energy impacts against axis end stops if
proper precautions are not in place. These tolerances can also lead to
undetected and repetitive high energy impacts against unexpected
obstructions. Such impacts can lead to equipment damage and/or serious
injury.
To identify the safety concerns that you have with default Position Error
Tolerance or after an Auto-Tune Function go to the Rockwell Automation
Knowlegebase. Click Find Technical Support Answers and search for
