1.1 Objective and Target Audience of this User Manual
This manual contains information on using the M-126 as intended.
It assumes that the reader has a fundamental understanding of basic servo systems as well as
motion control concepts and applicable safety procedures.
The latest versions of the user manuals are available for download (p. 3) on our website.
1.2 Symbols and Typographic Conventions
The following symbols and typographic conventions are used in this user manual:
CAUTION

Warning sign on the product which refers to detailed
information in this manual.
1.3 Definition of Terms
Term Explanation
Load Capacity Maximum load capacity in the vertical direction when the positioner
is mounted horizontally. The contact point of the load is at the center
of the platform.
Max. push/pull force Maximum force in the direction of motion. Some positioners may
have higher forces but this could limit the lifetime.
Incremental position
sensor
Sensor (encoder) for detecting changes of position or changes of
angle. Signals from the incremental position sensor are used for axis
position feedback. After the controller is switched on, referencing
must be done before absolute target positions can be commanded
and reached.
Pulse width modulation
(PWM)
PWM-controlled motors allow control of the motor performance with
a high-frequency-signal. This means that the power signal can be
separated from the digital control signal.
1.4 Figures
For better understandability, the colors, proportions, and degree of detail in illustrations can
deviate from the actual circumstances. Photographic illustrations may also differ and must not
be seen as guaranteed properties.

M-126 Precision Microtranslation Stage MP42E Version: 3.0.0 5
2.1 Intended Use
The M-126 is a laboratory device as defined by DIN EN 61010. It is intended for indoor use and
use in an environment that is free of dirt, oil and lubricants.
In accordance with its design, the M-126 is intended for single-axis positioning, adjusting and
shifting of loads at different velocities. The M-126 is not intended for applications in areas
where failure could lead to considerable risk to people or the environment.
The M-126 is intended for horizontal or vertical mounting. For the load limits with vertical
mounting, see "General Notes on Installation" (p. 17).
It is only possible to use the M-126 as intended when completely mounted and connected.
The M-126 must be operated with a suitable controller (p. 12). The controller is not included in
the scope of delivery of the M-126.
2.2 General Safety Instructions
The M-126 is built according to state-of-the-art technology and recognized safety standards.
Improper use can result in personal injury and/or damage to the M-126.
Use the M-126 for its intended purpose only, and only when it is in perfect technical
condition.
Read the user manual.
Eliminate any malfunctions that may affect safety immediately.
The operator is responsible for the correct installation and operation of the M-126.
