6 Start-Up and Operation
22 Version: 1.0.0 MP124E V-273 VC Linear Actuator
NOTICE
Undesired displacement due to lack of self-locking!
The drive of the V-273 does not have any 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 moving rod, e.g. due to the weight force of the moving mass.
As a result, the moving rod can move to the hard stop with a high velocity, and/or
collisions between the V-273, the load to be moved and the environment are
possible.

When the motion axis is aligned vertically or tilted: Perform 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 undesired displacements of the moving rod are possible.

Make sure that no collisions are possible between the linear actuator, the load to
be moved and the environment 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.
NOTICE
Damage from collisions!
Collisions can damage the linear actuator, the load to be moved and the
environment.

Make sure that no collisions are possible between the linear actuator, the load to
be moved and the environment in the motion range of the linear actuator.

Do not place any objects in areas where they can get caught by moving parts.

Stop the motion immediately if a controller malfunction occurs.

If possible, adapt the travel range limits of your mechanical system in the
software that you use for commanding the motion.
