1.3 Definition of Terms
Term Explanation
Load capacity Maximum load capacity in the vertical direction when the linear
actuator is mounted horizontally. The contact point of the load is at
the center of the motion platform.
Max. push/pull force Maximum force in the direction of motion. Some stages may have
higher forces but with limited lifetimes. In the case of vertical
mounting, the specified value (s. 29) for models without a gearhead
and brake only applies when the servo mode is on.
Rotary encoder The rotary encoder is a sensor for capturing changes in position.
Signals from the sensor are used for axis position feedback. After the
controller is switched on, a reference point definition must be
performed before absolute target positions can be commanded and
reached.
1.4 Further Applicable Documents
The devices and software tools from PI that are mentioned in this documentation are described
in separate manuals.

2 Safety
L-220 Linear Actuator MP149E Version: 1.3 3
2.1 Intended Use
The L-220 is a laboratory device as defined by DIN EN 61010-1. It is intended for indoor use and
use in an environment which is free of dirt, oil, and lubricants.
In accordance with its design, the L-220 is intended for single-axis positioning, adjusting and
shifting of loads at various velocities.
The intended use of the L-220 is only possible when installed and in conjunction with a suitable
controller. The controller is not included in the scope of delivery of the L-220.
2.2 General Safety Instructions
The L-220 is built according to state-of-the-art technology and recognized safety standards.
Improper use of the L-220 may result in personal injury and/or damage to the L-220.
Only use the L-220 for its intended purpose, and only use it if it is in good working
order.
Read the user manual.
Immediately eliminate any faults and malfunctions that are likely to affect safety.
The operator is responsible for the correct installation and operation of the L-220.
