The new Mercury 3000Si Dual Axis Averager encoder system provides unique capabilities for motion control. With real-time feedback
of two encoders plus averaging (or difference), smallest sensor size, and easiest alignment, performance capabilities are unmatched.
Imagine what you can do with this!
The Mercury 3000Si Dual Axis Averager provides unprecedented performance for high-accuracy rotary
positioning applications. By averaging two Mercury encoder sensors at high speed, your motion system
can use the average of the two signals directly for motion control feedback. Using two diametrically
opposed sensors, eccentricity errors are eliminated and rotary accuracy is increased. The industrystandard SPI serial data interface is ideal for encoders and produces extremely high resolution at high
motion speed - up to 30X faster than A-quad-B encoders. The SPI standard is supported by many DSP
chip manufacturers and is easy to implement in your OEM controller design.
Mercury sensors are smaller, higher performing, faster to install, and easier to set up and align than any
other encoder. The tiny sensor fits into very tight spaces, has broad alignment tolerances for fast and easy
setup and works in both linear and rotary applications.

Encoder Alignment
Mercury Solves this Problem for Good
Fussy alignment is no longer a concern. With Mercury’s
patented PurePrecision™ optics, advanced SmartPrecision™
electronics and LED alignment indicators, you can push the
sensor against your reference surface, tighten the screws and
you’re finished. Try that with brand X or Y.
This performance is possible thanks to relaxed alignment
tolerances, particularly in the theta Z axis. Mercury offers a
± 2° sweet spot– that’s a 300% improvement over the best
competitive encoder. And that will result in dramatic savings
in manufacturing costs.
No other commercially available encoder is easier to align,
easier to use, or easier to integrate into your designs.

Mercury Can Reduce System Size and Cost
Mercury’s sensor height is 44% shorter than competitive encoders,
making it easy to fit into your design. This reduction can also cut total
system weight and cost by allowing the use of smaller motors and
stages. Safe system operation is also enhanced thanks to Mercury’s
generous standoff clearance– 200% greater than other encoders.
And its standoff tolerance is 50% greater than the best alternative.
This significantly relaxes mechanical system tolerances,
while reducing system costs.

SmartPrecision
Electronics Module
The heart of the Mercury 3000Si Dual Axis Averager encoder system is its
SmartPrecision electronics module. This compact signal processing
system's FPGA architecture performs averaging (and differencing)
digitally, at ultra-high speed for high-precision, high-accuracy rotary
control. Features include:

High Speed Serial Interface
Motion system engineers who are optimizing their system can boost its performance by
interfacing their SPI-compatible controller with the Mercury 3000SiDAA. Its industry
standard SPI high-speed serial data interface is supported by multiple DSP chip
manufacturers, including TI, Motorola and Analog Devices, and provides a robust
connection that is ideal for encoder interfacing. With the Mercury 3000SiDAA, encoder
position values are sent directly into the controller's DSP. Limitations of encoders with
A-quad-B output are completely eliminated. Standard Mercury 3000SiDAA features
include:
• Very high motion speed with high encoder resolution - up to 7.2m/s movements
with 0.005µm* resolution
• 10MHz max. input clock frequency / 250kHz position word sample rate
• RS422 voltage levels are resistant to Electro Magnetic Interference and support
long cable runs
• Five different modes for adjusting or zeroing serial position data relative to the index
mark on the scale. Consult the Installation Manual or MicroE Applications
Engineering for further details.
Mode 0: No changes are made to the position word at the index mark.
Mode 1: Zeros the fringe counter at the first encounter with index mark after power
up.
Mode 2: Zeros the fringe counter at every encounter with index mark.
Mode 3: Zeros the fringe counter at the first encounter with index mark after power
up and subtracts the index position from the calculated position making the
index mark the zero position of the encoder.
Mode 4: Zeros the fringe counter at every encounter with index mark and subtracts
the index position from the calculated position making the index mark the
zero position of the encoder.

Status Word Definition
The data word, which includes the status and position words, is transferred with the most significant bit (MSB) first. The data word
length is up to 36 bits long. The most significant 8 bits are the status word. The next 28 bits are the position word. This position
word is large enough to keep track of a measurement length of 5.24 meters. The interpolation depth of the Mercury 3000SiDAA is
X1024. If the user prefers smaller interpolation depths then fewer spiClock signal clocks can be sent to the interpolator and fewer
bits will be shifted out. The Status Word may be set to occur at either the beginning or end of the 36 bit Data Word by using
SmartPrecision Software to set the Format to 0 or 1 (units are shipped with the output format set to 0).

Scale Specifications
Standard and Customized Scales
MicroE Systems offers a wide array of chrome on glass scales for the highest accuracy and best thermal stability. Easy to install, standard
linear and rotary scales meet most application requirements. Customized linear, rotary, and rotary segment scales are available where needed. All scales include an optical index. Mercury's glass scales save time by eliminating motion system calibrations or linearity corrections
required by other encoders, and provide better thermal stability than metal tape scales.
Options include:
• Standard linear: 18mm - 2m
• Standard rotary: 12mm - 107.95mm diameter, with or without hubs
• Custom linear*: special lengths, widths, thickness, index mark locations and special low CTE materials
• Custom rotary*: special ID's, OD's (up to 304.8mm), index mark outside the main track and special low CTE materials
• Mounting of hubs for rotary scales: MicroE Systems can mount and align standard, custom, or customer-supplied hubs
• Rotary segments*: any angle range; wide range of radius values
*Custom scales or rotary segments are available in OEM quantities. Contact your local MicroE Systems sales office.
