Page 12: Motor-Related Warnings
Hardware Manual 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 motor. -
Page 13: Pinch Points
(during normal operation, for example). when the system is moved manually (during the installation process or when you do maintenance, for example). Motors are capable of very high speeds and acceleration rates. Figure 1: Typical Pinch Point Locations www.aerotech.com... -
Page 14: Magnetic Hazards
Loose items such as metallic tools, watches, or keys could get drawn into and dam- age the magnet track assembly. IMPORTANT: Use non-magnetic tools when you install or do service to the stage. Figure 2: Exposed Magnet Locations www.aerotech.com... -
Page 15: Handling And Storage
Use a cart, dolly, or similar device to move the motor to a new location. Gently set the motor on a smooth, flat, and clean surface. Use compressed nitrogen or clean, dry, oil- free air to remove any dust or debris that has collected during shipping. www.aerotech.com... - Page 16 Before you operate the motor, let it stabilize at room temperature for at least 12 hours. This will ensure that all of the alignments, preloads, and tolerances are the same as they were when they were tested at Aerotech. Storage Store the motor in the original shipping container.
