QNP3 Hardware Manual
Chapter 4: Maintenance
The QNP3 series stages are designed to require minimum maintenance. This chapter will detail the cleaning
process and specify recommended cleaning solvents.
4.1. Service and Inspection Schedule
D A N G E R : To minimize the possibility of bodily injury or death, disconnect all electrical
power prior to performing any maintenance or making adjustments to the equipment.
Inspect the QNP3 at least once per month. A longer or shorter inspection interval may be required depending
on the specific application, and conditions such as the duty cycle, speed, and environment.
Visually inspect the stage and cables once per month to:
Re-tighten loose mounting screws.
l
Replace or repair damaged cables.
l
Clean the QNP3 stage and any components and cables if needed.
l
Assess any damage to the QNP3 stage .
l
In general, repair and/or replacement of damaged or malfunctioning components by Aerotech field service
personnel is not possible. Repair typically requires that the unit be returned to the factory. Please contact
Aerotech Global Technical Support for more information.
4.2. Cleaning and Lubrication
W A R N I N G : In applications that have multiple stages bolted together to form multi-axis
systems, the orthogonality may be lost if the stage tables of the support stages are loosened.
Precision aligned stages should not be loosened or disassembled.
W A R N I N G : Further disassembly of the stage is not recommended because proper
assembly and calibration can only be done at the factory. In addition, a laser interferometer is
required for post assembly verification to maintain warranties. Contact Aerotech for more
information.
There are no elements on QNP3 stages that require lubrication.
Before using a cleaning solvent on any part of the QNP3, blow away small particles and dust with nitrogen
or, less preferably, clean, dry, compressed air.
Any metal surface on the stage can be cleaned with either acetone or isopropyl alcohol.
