ASR1200 Rotary Stage User's Manual Overview
Chapter 1: Overview
Aerotech’s ASR1200 mechanical-bearing rotary stage is a system that combines high precision rotary posi-
tioning with an integrated pneumatically controlled collet chuck for material handling. The ASR1200 series util-
izes direct-drive brushless motor technology to maximize positioning performance and virtually eliminate the
need for maintenance. The stage is also equipped with a rotary union attachment for wet cutting operations.
These features make the ASR1200 an ideal choice for applications where low maintenance, high throughput,
and low total cost of ownership are essential.
The ASR1200 has been designed with a collet chuck that can support ER16 collets (manufactured to
DIN6499 specs) to allow for a wide range of materials and applications. This product is intended for light
industrial manufacturing or laboratory use.
This chapter introduces standard and optional features of the ASR1200, explains the model numbering sys-
tem, and gives general safety precautions. Figure 1-1 shows a typical ASR1200.

N O T E : Aerotech continually improves its product offerings, and listed options may be superseded at any
time. Refer to the most recent edition of the Aerotech Motion Control Product Guide for the most current
product information at www.aerotech.com.
N O T E : This manual should be read in its entirety before operating the ASR1200 system.
Failure to follow the maintenance procedures outlined in Section 4.3.3. will result in voiding of
warranty.

Overview ASR1200 Rotary Stage User's Manual
1.1. Standard Features
1.1.1. Rotary Axis
ASR1200 stages come standard with a direct drive brushless motor with a non-contacting integral rotary
union. These features combine to create a low friction, low maintenance rotary stage capable of high accel-
erations and low positioning error. With a non-contact rotary union, there are no seals to be replaced or lubri-
cated allowing for a lifetime of maintenance free performance. The brushless, slotless motor design allows
for extremely high torque coupled with smooth motion. There are no brushes to wear, no belts to tension, and
no gears to wear resulting in a completely maintenance-free motor.
The ASR1200 is designed with an ER16 style collet chuck. The maximum tube diameter supported by the
ER16 collet chuck is 5.8 mm. The collet is retained with a threaded collet nut enabling quick changeover. It
is configured in a “fail-safe” normally-closed mode where full clamping force is applied when no air pressure
is present.
N O T E : Aerotech recommends using electro-polished collets manufactured to DIN6499 specs.
1.1.2. Wet Cut
The ASR1200 rotary stage has a standard wet cut rotary union that is used for fluid delivery (@ 100 psi max
pressure) in wet laser cutting applications. A 1/4" NPT tapped hole is supplied on the rear of the rotary to
allow for connections of different length pressure vessels depending on the tube length being cut. See Sec-
tion 3.4. , Section 4.3.3. , and Section 4.4. for details regarding use and maintenance of the wet cut rotary
union.
N O T E : The purchase of a ringseal will also be required based on the tube diameter used in the cutting
application. Consult Aerotech for more information.
