High guide accuracy and stiffness due to ball screws and crossed roller guides. Stress-relieved aluminum base for high stability. Vacuum-compatible product variants on request. Noncontact limit and reference switches (Hall effect). Reference switch with direction sensing in the middle of the travel range.
Applications and use cases
Precision positioning in industry and research
Applications with high duty cycles
Technology
The following drive types are available:
2-phase stepper motor for high torque even at low velocities and high resolution
DC servo motor
Brushless DC motor (BLDC) for high rotational velocity. Smooth running and low wear, therefore longer lifetime.
The following options are available for position measuring:
Variants with DC motor: Rotary encoder
Optional: Integrated linear encoder, installed centrically.
Noncontact optical linear encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement.
Minimum incremental motion and slow motion: In conjunction with an ACS controller (e.g., ECMsm-4B44T-NNNNN), variants with a stepper motor and an integrated linear encoder (L-310.xASD) achieve repeatable minimum incremental motion in the range of the sensor resolution. The same configuration achieves constant low velocities of a few sensor increments per second.

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.
