■ Typical equipment Reduction gear thickness + motor length + space for motor removal Equipment needs increased space Cable routing is difficult ■ RD2 Series Only the thickness of the reduction gear itself Right angle and pulley models can be used for a lower profile Allows routing of cables. Hollow shaft series also available Improved layout Backlash: 1 arc.min for straight input and pulley input type 1.5 arc.min for right angle input type (except some models) High backlash leads to poor repeatability Highly precise positioning is possible 7

Difference Between RD Series and RD2 Series 1. Simplified motor mounting Integrated coupling makes mounting easy With the previous series, the coupling was an accessory, but on the RD2 Series the coupling is built into the input unit. This simplifies the process of mounting the servo motor to the reduction gear. 2. Compact design Reduced total length Compared to the previous series, the total length in the axial direction has been reduced by up to 15%. Note: • Use of the same motor model is being studied. • This diagram shows a comparison between the RD-010C and the RDS-010C. 3. Center pipe rotates...
