Notes:
1. Certified with each stage. Requires the use of an Aerotech controller.
2. In-Position Jitter listing is 3 sigma value.
3. Axis orientation for on-axis loading is listed.
• Specifications are per axis, measured 25 mm above the tabletop. Consult factory for multi-axis or non-standard applications.
• All error motion specifications are measured at 60 rpm.
• For high speed operation, customer payload must be balanced to G1.0 per ISO 1940

Notes:
1. Linear
amplifiers are required to achieve the listed specifications. Other options are
available.
Note: To ensure the achievement and repeatability of specifications over an extended period of time, environmental temperature must be controlled to within 0.25ºC/24 hours. If this is not possible, alternate products are available. Please consult Aerotech Sales Engineering for more information.
