1) With x4 evaluation; system can be delivered with standard analog SIN/COS encoder interface for personal interpolation.

2) Absolute Accuracy & Bi-Directional Repeatability measurements are processed with Zygo ZMI 501 Michelson laser interferometer.

3) Pitch & Yaw measurements are processed with 11D-ALI-COL electronic autocollimator. Resolution of 11D-ALI-COL: 1 µrad. Environment error: 1 µrad.

4) Maximum Velocity is electrically limited by encoder and driver CUT-OF frequency; maximum velocity is also limited by guiding system.

5) Maximum Acceleration is limited by Drivers` Peak Current, Motors` Peak Current and External Load (inertia). Please contact Standa for support.

6) Load Capacity is limited by position of load and integrated guiding system. Please contact Standa support for loading calculation.

7) Moving Mass is constant parameter of system which characterize m0 or inertia of unloaded system.

8) Recommended controllers & Recommended drivers can be optimized for a certain application. Please contact Standa support for recommendation.

9) Recommended power supply depends on required duty cycle and load. Please contact Standa support for recommendation.

10) Differential Outputs are available in passive (buffered) or active (modulated) way with LCMv2.

11) Stages can be assembled with better orthogonality by request.

12) Scalar Control can be implemented with USB / TCP-IP / RS-232 communication iterface; for vector control we recommend to use EtherCAT.
