Installation Guidelines for Piezo LEGS
®
The Piezo LEGS is a high precision motor. A few simple instructions must be followed
in order to get the best performance and lifetime. If the motor is installed poorly
both performance as well as life time is severely affected.

The Piezo LEGS is a direct drive motor. Proper friction coupling between drive legs and
drive rod is essential for optimum performance. When properly installed the motor
can position down to the nanometer range without backlash.
Mechanical Notes
•t The motor drive rod must not be subjected to non-axial force – even small loads
or torques on the end of the drive rod may cause loss of proper friction contact
between drive legs and drive rod. The motor function can be impaired and the
motor can be damaged.
