(1) Reduction ratio
The symbols (20A, 30A, 50A) in the following table indicate the model numbers of the reducers
assembled to the servo motors. Geared servo motors having the indicated reducer 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 °
