1) Absolute Accuracy & Bi-Directional Repeatability measurements processed by Zygo ZMI 501 Michelson laser interferometer.
2) Pitch & Yaw measurements are processed by 11D-ALI-COL electronic autocollimator. Resolution of 11D-ALI-COL: 1 µrad. Environment error: 1 µrad.
3) Maximum Velocity is electrically limited by encoder and driver CUT-OF frequency; maximum velocity is also limited by guiding system.
4) Maximum Acceleration is limited by Drivers` Peak Current, Motors` Peak Current and External Load (inertia). Please contact Standa for explanation.
5) Load Capacity is limited by position of load and integrated guiding system. Please contact Standa for loading calculation.
6) Moving Mass is constant parameter of system which characterize m0 or inertia of unloaded system.
7) Recommended controllers & Recommended drivers can be optimized for a certain application. Plaese contact Standa for recommendation.
8) Recommended power supply depends on required duty cycle and load. Please contact Standa for recommendation.
9) Differential Outputs are available in passive (buffered) or active (modulated) way with LCMv2.
