3 Product Description
12 Version: 1.1.4 MP155E V-273 VC Linear Actuator
PC software is included in the scope of delivery of the controllers from PI. The operation of the
controllers is described in the corresponding user manuals.
Please note that the cable for connecting the V-273 to the electronics must also be ordered
separately.

To order, contact our customer service department (p. 35).
3.5 Technical Features
3.5.1 Linear Encoder
The V-273 is equipped with an optical linear encoder. For the resolution, refer to the table in
the "Specifications" section (p. 37).
Optical linear encoders measure the actual position directly (direct metrology). Therefore,
errors occurring in the drivetrain such as nonlinearity, backlash or elastic deformation, cannot
influence the measurement of the position.
3.5.2 Reference Switch
The V-273 is equipped with a direction-sensing reference switch, which is located at about the
midpoint of the travel range. This sensor transmits a TTL signal that indicates whether the linear
actuator is on the positive or negative side of the reference switch.
See the controller user manual and/or associated software manuals for the commands that
make use of the reference point signal.
For more information, see "Reference Switch Specifications" (p. 39).
3.5.3 Force Sensor
The V-273.441 is equipped with a force sensor. The force sensor is mounted on the runner
(p. 8).
The force sensor allows application of a defined force and measurement of the counterforce
that is applied orthogonally to the contact part of the sensor (p. 20). Forces up to 10 N can be
measured and forces up to 6 N can be applied, each with an open-loop resolution of 1 mN.
The force sensor works as an incremental sensor. When the controller is switched on or
rebooted, the connected force sensor always measures 0 N, regardless of the actual force
exerted on the force sensor.
3.5.4 Adapter with ID Chip for Connecting to the C-413.2xx Controller
The V901B0030 adapter is adapted at the factory to the V-273 to achieve optimum positioning
accuracy.
The adapter has an ID chip on which the following data is stored:
