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.

3.7 Suitable Controllers
The version of the M-126 with electric drive must be connected to a suitable controller. The
following controllers from PI are suitable for operating the M-126:
Models Controller
M-126.XG1, M-126.PDx C-863, C-884
M-126.2S1 C-663
The required PC software is included in the scope of delivery of the controllers from PI.
Operating the controllers is described in the corresponding user manuals.
Note that the cables required for connecting the M-126 to the controller and the required
adapter must be ordered separately.
To order, contact our customer service department (p. 31).
3.8 Technical Features
3.8.1 Encoder
The M-126.XG1 and M-126.PDs models are equipped with an incremental rotary encoder.
A rotary encoder is implemented at a rotating point in the drivetrain, e.g., the motor shaft. The
controller counts the encoder signals, (pulses), in order to determine the relative position.
3.8.2 Limit switches
The M-126.XG1 and M-126.PDx models are equipped with noncontact Hall effect limit switches.
Each limit switch sends its signal to the controller on a dedicated line. The controller then stops
the motion. If the controller does not stop the motion in time, the positioner runs into the hard
stop.
Refer to "Limit Switch Specifications" (p. 35) for further information.
3.8.3 Reference Switch
The M-126.XG1 and M-126.PDx models are equipped with a direction-sensing reference switch
positioned at approx. the midpoint of the travel range. This sensor sends a TTL signal that
indicates whether the positioner is on the positive or negative side of the reference switch.
The commands that use the reference signal are described in the user manual for the
controller.

3 Product Description
M-126 Precision Microtranslation Stage MP42E Version: 3.0.0 13
3.8.4 Integrated PWM Amplifier
The M-126.PDx models are equipped with a PWM amplifier ("ActiveDrive concept"). The PWM
amplifier only receives the PWM control signals from the controller, whereas the supply voltage
is provided via an external power adapter. The ActiveDrive concept allows high motor power
and dynamics at low power loss.
