(1) Reduction ratio
The symbols (11B, 14A, 20A, and 32A) in the following table indicate the model numbers of the reducers
assembled to the servo motors. Servo motors with a reducer having the indicated reduction gear model
numbers are available. The reducer model number indicates _ _ _ of the reducer model HPG-_ _ _-05.

2. The reducer efficiency differs depending on the reduction ratio. Also, it changes depending on the
operating conditions such as the output torque, speed and rotation, temperature, etc. The numerical
value in the table is a typical value in the rated torque, rated speed and rotation and typical
temperature, and not a guaranteed value.
3. The backlash can be converted: 1 min = 0.0167 °
