PD1D Piezo Inertia Drive Stage Chapter 2: Safety
Rev A, August 3, 2021 Page 3
2.3. General Cautions
CAUTION
Dust and debris can reduce the lifetime of the stage. If left running unattended for extended periods of
time, the application should be covered where possible.
If the clamping force onto the moving platform is too high, this can cause reduced stepping
performance and possible stalling of the stage.
The stage’s screws are well adjusted and fixed. Loosening or removing any screws will change the
performance and invalidate the warranty, except where instructed to do so in this manual.
2.4. General Notes
NOTE
The slip-stick function of the mechanism uses a very short pulse width.
Continuous stepping of the stage results in an audible noise at a typical level of 60 to 70 dB.
The step size is defined as the distance moved in one step or pulse. This distance can be increased
by up to about 30% by changing the piezo drive voltage. The actual step size achieved for a given
drive voltage will be dependent on the application. Due to the open loop design, piezo hysteresis,
component variance, and application conditions, the achieved step size of the system may vary by
over 20% and is not normally repeatable.
