NOTICE
Attracting magnetizable objects!
The magnets in the V-273 can attract magnetizable parts, e.g., loose screws. Objects attracted
can damage the V-273.

Make sure that there are no movable, magnetizable objects within a radius of at least
10 cm around the V-273's housing.

Take appropriate precautions for storage and transport.
NOTICE
Damage to magnetically sensitive objects!
The magnets in the V-273 can damage parts susceptible to magnetic influences, e.g., magnetic
data carriers and electronic devices.

Make sure that there are no magnetically sensitive objects within a radius of at least 10 cm
around the V-273's housing.

Take appropriate precautions for storage and transport.
NOTICE
Operating voltage too high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to the V-273.

Operate the V-273 only with controllers/drivers and original accessories from PI.

Do not exceed the operating voltage range (p. 38) for which the V-273 is specified.

Operate the V-273 only when the operating voltage is properly connected; see "Pin
Assignment" (p. 43).
NOTICE
Undesired displacement due to lack of self-locking!
The drive of the V-273 does not have self-locking. Switching off or rebooting the controller or
switching off the servo mode for the axis can therefore lead to undesired displacements of the
runner, e.g., due to the weight force of the moving mass. As a result, the runner can move to
the hard stop with a high velocity, and/or collisions between the V-273, the load to be moved
and the surroundings are possible.

When the motion axis is aligned vertically or tilted: Run an autozero procedure for the axis
on the controller so that the weight force of the moving mass is also compensated for
when the servo mode is switched off. For details, see the user manual of the C-413.

Before switching off or rebooting the controller, take suitable measures to ensure that no
unintentional motion of the runner is possible.

Make sure that no collisions are possible between the linear actuator, the load to be
moved, and the surroundings in the motion range of the linear actuator.

Ensure that the end of the travel range is approached at low velocity and with low force.
