Product overview
The directly driven low-profile rotation stages of the PIglide RL series are designed for the highest precision with low-profile design. Various options can be combined to create a solution ideal for point-to-point indexing or constant velocity scanning. The RL stages offer superior travel accuracy, flatness, and wobble performance.
3-Phase torque motor
- Brushless
- Slotless
- Low cogging torque
Absolute encoder (optional)
Absolute encoders supply explicit position information that enables immediate determination of the position. This means that referencing is not required during switch-on, which increases efficiency and safety during operation.
Accessories and options
- Incremental or absolute encoder
- Vacuum feedthrough
- Self-locking at rest by magnetic preload
- Clear aperture on request
- PIglide filter and air preparation kit
- Single or multi-axis motion controllers and servo drives
- Multi-axis/customized setups
- Base plates made of granite and systems for reducing vibration
Application fields
Optical alignment, wafer inspection, wafer alignment, measuring technology, inspection systems, calibration, scanning.
Thanks to the friction-free motion, no particles are formed, which makes PIglide stages ideal for cleanroom applications.

Note on linear and rotational crosstalk: Dependent on the quality of the underlying surface, the payload, orientation, and forces that act on the stage from the outside. Please contact PI for
application-specific parameters. The specified values are static (no rotary motion during measuring) and without load.
Note on permissible push force and permissible torque: The values listed assume a supply pressure of 550 kPa (80 psi). Please contact PI if other pressures are required.
Note on angular velocity: May be limited by the payload, payload imbalance, controller or drive.
Note on sensor resolution for A-63x.A100: Assumes 4096x interpolation. Contact PI for the use of other factors.
Note on positioning accuracy: The specified values are based on error compensation controlled by the controller. The stage must be ordered with an A-8xx series controller from PI to reach these values. Accuracy values assume short-term duration and do not consider the long-term effects of thermal drift on the stage.
Note on operating pressure: To protect the stage against damage, it is recommended to connect an air pressure sensor to the Motion-Stop input of the controller.
Ask about customized versions.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
