12. SERVO MOTOR
(c) Permissible loads of servo motor shaft
The permissible radial load in the table is the value measured at the center of the gear reducer output
shaft.
(2) For high precision application
(a) Reduction ratio
The symbols (11B, 14A, 20A, and 32A) in the following table indicate the model number of the gear
reducer assembled to the servo motors. Geared servo motors having the indicated gear reduction
model numbers are available. The gear reducer model number indicates
model HPG-
