2.1 Intended Use
The N-422 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.
The N-422 is a linear drive for integration in motion systems used for positioning, adjusting and
displacing an object (load) on an axis. For integration purposes, the mechanics into which the
N-422 is to be installed must have suitable guides. The N-422 can be mounted horizontally or
vertically.
The N-422 linear drive uses the principle of inertia (stick-slip effect). The feed of the runner is
produced by alternating static and sliding friction between the runner and a cyclically activated
piezo actuator. The object (load) which is to be moved is coupled with the moving runner.
The drive is self-locking at rest, requires no current, and does not generate any heat. It holds
the position with maximum force.
The N-422 is not intended for continuous operation. Refer to "Technical Data" (p. 31) for
further information on the operating conditions of the N-422.
The intended use of the N-422 is only possible in conjunction with suitable drive electronics
which have the necessary operating voltages. The drive electronics are not in the scope of
delivery of the N-422. PI offers suitable drive electronics p. 9.
External position sensors and a position controller are required for the closed-loop operation of
a motion system with N-422 drive and drive electronics.
2.2 General Safety Instructions
The N-422 is built according to state-of-the-art technology and recognized safety standards.
Improper use of the N-422 may result in personal injury and/or damage to the N-422.
Use the N-422 for its intended purpose only, and only when it is in perfect condition.
Read the user manual.
Immediately eliminate any faults and malfunctions that are likely to affect safety.
The operator is responsible for installing and operating the N-422 correctly.
