• ±360 degrees of motion (continuous turn operation available)
• Mounting option on L08 module carriage or L08 module body
All external dimension and weight specifications for each module type can be found on
the module specification drawings located on the Adept website.
The LT1 Theta module utilizes heavy duty radial ball bearings to support its output shaft.
The basic load ratings for these bearings are given in the following table.
The motor used in the LT1 Theta module is a high-quality AC motor manufactured by
Yaskawa corporation. These motors employ serial absolute encoders. The motor model
numbers, size, maximum torque values, and encoder resolution are provided here for
reference.
