(a) Manufacturing range
The symbols (14A, 20A, 32A) in the following table indicate the model numbers of the reduction gears
assembled to the servo motors. Servo motors with a reduction gear having the indicated reduction gear
model numbers are available. The reduction gear model number indicates of the reduction
number model name HPG- -05...

2. If the above indicated value is exceeded, please contact your local sales office.
3. The reduction gear efficiency differs depending on the reduction ratio. Also, it varies
depending on the use conditions such as the output torque, speed, temperature, etc. The
numerical value in the table is a typical value in the rated torque, rated speed and typical
temperature, and not a guaranteed value.
4. The reduction gear efficiency of the HF-KP053 is 22 to 41%.
