technical notes

 1 All accuracy data is based on no-load conditions.

Contact ORBIT/FR for accuracy under load conditions.

 2 AL-260-1P and larger models are equipped with

adjustable limit switches capable of approx
20° to 900° total travel. When rotary joint and slip
ring options are specifi ed, limit switches remain
but are electrically disabled.
Single-axis positioners are factory-set at:

• Polarization Axis: 400° (± 200°)

 3 Slip Ring & Rotary Joint Option Notes:

• Certain slip ring options may require an extension
cap that protrudes above the turntable surface.
Positioner height may increase. Consult ORBIT/FR.

• Slip ring contacts for customer use are provided

with dedicated connectors.

• When rotary joint and/or slip ring options are

specifi ed, no central thru-hole is available
to the user. Option TH002 and TH003 are available
in lieu of rotary joint and/or slip ring options.

 4 AL-260-1P and larger models are delivered standard

with synchro

 5 AL-060-1P & AL-160-1P Models:

• Contain restricted limit travel settings.

Consult ORBIT/FR.

• Rated for indoor use only.

• Encoder accuracy is ± 0.03° in uni-directional

rotation and ± 0.1° in bi-directional rotation
(due to backlash).

• Interface readout - incremental encoder,

(synchro not available), interfaces with AL-4160
series motion control systems only.

 6 AL-260-1P is rated for indoor use only.
