1.0. Introduction
As
the complexity and specification requirements of today's optical systems increase, so does the
need for high performance, high accuracy, and compact mirror positioning systems. The
MicroMax™ Series 670 system was designed for applications that require high performance
specifications.
The Series 670 Single axis Board-Level Mirror Positioning System consists of a single-channel
servo amplifler on a 2.50" x 4.00" board and a high performance scanner. The scanner is
designed for a specific range of inertial loads, allowing mirrors with inertias from less than 0.001
gm-cm^ to greater than 100,000 gm-cm^ to be precisely controlled.
This manual describes the 670 servo board electronics. (A separate manual will describe the
particular motor matched to this system.) This manual describes the servo board in detail so the
user can better integrate this mirror positioning sub-system into the end use application. At the
end ofthe manual is a complete set of schematics and assembly drawings.
Please read this manual in order to fully understand the operation of this mirror positioning
system. The optical scanners used in this system are delicate devices and can be damaged if
mishandled. Do not attempt to retune the drive electronics until the tune-up procedure in section
6.0. is fully understood. Failure to do so could result in serious damage to both the scarmer and
electronics.
