  • Page 10: Installation And Operation

    AGV-XPO Hardware Manual Installation and Operation To decrease the risk of damage to the equipment, you must obey the precautions that follow. DANGER: General Hazard Warning! This product can produce high forces and move at velocities that could cause injury. The user is responsible for its safe operation.

  • Page 11: Laser Safety

    Classes of Lasers The AGV-XPO series scan head can be used with a variety of lasers. Each laser is assigned a particular hazard level, which is indicated by the Laser Class label that is affixed to the device near the location where laser radiation is emitted.
  • Page 12 Class I, IIa, or II laser device. The AGV-XPO can aim the laser beam over an approximately pyramidal volume. When the scan head is used in conjunction with a laser device that can generate a sufficiently intense beam, a laser area will be produced that includes the aiming volume as well as the reflections from all objects that can be exposed to the radiation.
  • Page 13 The AGV-XPO scan head does not include a laser attenuator, and therefore it cannot block or reduce the intensity of the laser beam. Due to the unique properties of each laser, it is the responsibility of the user to incorporate an appropriate shutter as per any and all applicable regulations in order to prevent unwanted emission of the laser beam.

  • Page 14: Electrical Warnings

    It is the responsibility of the End User/System Integrator to make sure that scan heads are properly connected and grounded per Engineering Standards and applicable safety requirements. It is the responsibility of the End User/System Integrator to configure the system drive or controller within the Aerotech motor/scan head electrical and mechanical specifications. www.aerotech.com...

  • Page 15: Motor-Related Warnings

    Hardware Manual AGV-XPO 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 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 scan head.

  • Page 16: Pinch Points

    AGV-XPO Hardware Manual Pinch Points A pinch point is a mechanical hazard that can occur when there are exposed parts of the scan mirrors or system that can move. For example, the travel of a stage tabletop could expose the user to a pinch point between the tabletop and the stage housing.

  • Page 17: Handling And Storage

    Do not use the focal lens or exit aperture as a lift surface. Make sure that the lens cap is attached before you move the AGV-XPO. Put the scan head on a soft surface when it is not attached to its mounting surface to pro- tect the optics.
  • Page 18 AGV-XPO Hardware Manual Unpacking and Handling WARNING: Electrostatic Discharge (ESD) Sensitive Components! Wear an ESD wrist strap when you handle, install, or do service to the system assembly. You could damage the power supply or drives if you fail to observe the correct ESD practices.

  • Page 19: Chapter 1: Overview

    Figure 1-1: Functional Principle of a 2-Axis Galvanometer Scanner The AGV-XPO control connections are two 25-pin D-style connectors. The AGV-XPO is also available with right-side and left-side input apertures for “mirror image” machine builds or side-by-side scanner mounting with a single laser beam split to source both scanners.

  • Page 40: Securing The Scan Head To The Mounting Surface

    The mounting surface should be flat and have adequate stiffness in order to achieve the maximum performance from the AGV-XPO scan head. When an AGV-XPO is mounted to a non-flat surface, the scan head can be distorted as the mounting screws are tightened. This distortion will affect the alignment between the galvo motors and decrease the overall accuracy of the scan head.
  • Page 41 3. Clean the mounting flange and the mating surface of the scan head with the appropriate cleaners (isopropyl alcohol for the scan head). 4. Line up the dowel hole and slot features of AGV-XPO scan head with the dowel pins protruding from the mounting flange.

  • Page 42: Attaching The Focal Lens To The Scan Head

    The procedure outlined in this section is provided as a general reference for how to remove or install a focal lenses (F-Theta lenses). A lens adapter is required to attach the focal lens to the AGV-XPO series scan head. This lens adapter is supplied with optics configurations that include a focal lens. For AGV-XPO scan heads that are provided without a focal lens, the user is responsible for supplying both the F-Theta lens and the necessary lens adapter.

It does not actively cool the individual motors. The -WC...

  • Page 45: Water Requirements

    AGV-XPO 2.5. Water Requirements WARNING: To prevent damage to the AGV-XPO, do not attach a water hose to an air fitting or an air hose to a water fitting. WARNING: Use distilled water as the coolant in the AGV-XPO water-cooling system. Do not use deionized (DI) water.
