6 Startup and Operation
N-412 Piezo Motor Rod Drive
N412T0001
Version: 1.2.1

NOTICE
Operating voltage too high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to the N-412.
Only operate the N-412 with electronics and original accessories from PI.
Do
not
exceed the maximum operating voltage (p. 21) for which the N-412 is specified.
Operate the N-412 only when the operating voltage is properly connected; see “Pin
Assignment” (p. 24).
NOTICE
Operating frequency too high!
An operating frequency that is too high can cause damage to the N-412.
Only operate the N-412 with electronics and original accessories from PI.
Do
not
exceed the maximum operating frequency (p. 21) for which the N-412 is specified.
NOTICE
Increased friction due to lateral forces on the moving part!
Lateral forces that act on the moving part and the ball tip of the linear drive increase the
friction on the internal drive components. Increased friction impairs the motion of the moving
part and increases the wear of the drive components.
Avoid lateral forces on the moving part and on the ball tip of the N-412.
Install the N-412 so that the moving part is aligned vertically to the contact surface of the
moving part of the mechanical mounting.
NOTICE
Damage from collision of the N-412 with the hard stop!
When the hard stop has been reached or the drive is blocked, but the drive is still being
operated, this can cause damage or lead to considerable wear on the drive.
Do
not
place any objects in areas where they can get caught by moving parts.
Do
not
continue to operate the N-412 at the end of the travel range.
INFORMATION
The drive electronics are adapted via parameters to the N-412. Changing parameter values can
cause undesirable results.
Operate the N-412 only when the parameters of the drive electronics have been correctly
set, see “Operating Parameters of the N-412” (p. 17).
For further information on the operating conditions, refer to the “Technical Data” section
(p. 20).
The N-412 is started up with the E-872.401 drive electronics (p. 11) from PI.
