Micro Step..New development
•
Micro-step uses existing hardware
•
Actuator resolution
– Current = 3.41 microns
– Micro-step = 0.4 microns
Issue 2: July 2007
– Micro-step = 0.4 microns
•
Micro-step uses 1/8
th
step card configuration
•
Will introduce a ‘jiggle’ effect I.e. every
alignment movement (even 0 microns) will
have a backwards and forwards move into
position
•
No effect on cycle time
Simple dc motor
