Ideal for applications requiring stable operation under heavy inertia loads
Pursues positioning accuracy and rotation runout accuracy
Achieves stable operation even with an inertia ratio of 2,000 times (with conditions)
Supports SSCNET III/H, CC-Link, EtherCAT, and MECHATROLINK-III
*Absolute encoder types are included in the standard lineup. For the following models, incremental encoder types can also be made to order; however, note that this will require additional delivery time. ・DD160-96 / 146, DD250-90 / 138 / 163

* 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. A: Incremental/C: Absolute *3 Shown in parentheses are the values of the high-accuracy specification (option). *4 The bearing life and the runout accuracy differ with the load. *5 If you request radial/axial runout accuracy exceeding 3 μm, contact our sales representative. *6 Shown in parentheses are values for parallelism machining specifications. Parallelism machining specifications are an optional set with radial/axial runout high-accuracy specifications. *7 Shown in parentheses is the maximum torque of the paired driver.
