Notes:
1. Special cell adapters and slip ring assemblies available by
special order.
2. ±24 μrad calibrated; ±144 μrad uncalibrated.
3. Maximum speed based on stage capability; maximum application
velocity may be limited by system data rate and system resolution.
4. With x500 multiplication on AS encoder.
5. Tolerance equals +0/-0.25.
6. Unloaded inertia. |
