14. SERVO MOTOR
14.6.3 Servo motors with reduction gears
CAUTION
The servo motor with reduction gear must be installed in the specified direction.
Otherwise , it can leak oil, leading to a fire or fault.
For the servo motor with reduction gear, transport it in the same status as in the
installation method. Tipping it over can cause oil leakage.
Servo motors are available with reduction gears designed for: general industrial machines and precision
applications.
Servo motors with electromagnetic brakes are also available.
(1) Manufacturing range of servo motor with reduction gear
Servo motors with reduction gears that may be manufactured are indicated by symbols (G1(H), G2) in
the following table. G1 (H) and G2 are symbols appended to the servo motor models.
