Ideal for various applications because of high performance, excellent cost performance, and a wide range of options
Compact yet high torque
Ideal for direct drive from an AC servo motor + reduction mechanism
Supports SSCNET III/H, CC-Link, EtherCAT, and MECHATROLINK-III
* Absolute encoder types are included in the standard lineup. Incremental encoder types can also be made to order; however, note that this will require additional delivery time.

* The specification values are those obtained when the τDISC is mounted on a heat sink (aluminum plate) and operated at the ambient temperature for use. For details, refer to the individual specifications in the catalog. *1 Shown in parentheses is the motor type or model of the high-accuracy specification (option). *2 The □ in the model differs with the encoder type. I: Encoder type Incremental/J: Encoder type Absolute *3 Shown in parentheses is the value of the high-accuracy specification (option). *4 When the motor speed is 4 rpm: 4.5 N･m/When the motor speed is 6 rms: 4.1 N･m. *5 Shown in parentheses is the rated or maximum torque when a paired driver is used. *6 The bearing life and the runout accuracy differ with the load. *7 Parallelism machining specifications are an optional set with radial/axial runout accuracy specifications.
