Chapter 4: Maintenance
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.
4.1. Service and Inspection Schedule
Lubricant inspection and replenishment in AMG series stages depends on conditions such as duty cycle,
speed, and the environment. An inspection interval of once every two weeks is recommended until a trend
develops for the application. Longer or shorter intervals may be required to maintain the film of lubricant on
the worm threads.
In general, stages that operate in a clean environment at 50% duty cycle or less must be lubricated monthly
or every 75,000 revolutions (which ever comes first). For long-term reliability, we recommend that you return
the stage to Aerotech after 300,000 rotation cycles for cleaning, relubrication, and gearing adjustments. For
stages that operate at higher duty cycles, lubrication once every two weeks is recommended.
If the application process uses only a small portion of travel for most of the duty cycle, periodically drive the
stage through full travel to redistribute the lubrication in the bearingsand worm drive.
Monthly inspections should include but not be limited to:
l
Visually inspect the stage and cables.
l
Re-tighten loose connectors.
l
Replace or repair damaged cables.
l
Clean the AMG and any components and cables as needed.
l
Repair any damage before operating the AMG.
l
Inspect and perform an operational check on all safeguards and protective devices.
4.2. Cleaning and Lubrication
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.
Cleaning
Before using a cleaning solvent on any part of the AMG, blow away small particles and dust with nitrogen or,
less preferably, clean, dry, compressed air.
Any external metal surface of the AMG can be cleaned with isopropyl alcohol on a lint-free cloth.
W A R N I N G : Make sure that all solvent has completely evaporated before attempting to
move the stage.
Lubrication
There are no elements on AMG stages that require lubrication.
