1/5 (60 × 60): 12%, 1/11, 1/21, 1/33 and 1/45 of HG-KR053(B)G5: 22% to 34% 1/5 (40 × 40) and 1/9 of HG-KR053(B)G5, and HG-KR13(B)G5 to HG-KR73(B)G5: 48% to 84% Notes: 1. The moments of inertia in the table are the values that are converted into motor shaft of the servo motor with gear reducer (and with electromagnetic brake). 2. Contact your local sales office if the load to motor inertia ratio exceeds the value in the table. 3. The values in brackets represent the dimensions of flange. 4. The gear reducer efficiency varies depending on the reduction ratio and also varies with the conditions of use, such as output torque, speed, and temperature. The values in the table represent typical values at the rated torque and speed and at the normal temperature. They are not guaranteed values. 5. The backlash can be converted: 1 minute = 0.0167˚
