7.6 Geared servo motors
CAUTION
Geared servo motors must be mounted in the specified direction. Otherwise, it
can leak oil, leading to a fire or malfunction.
For the geared servo motor, remove the oil before transportation and installation.
Tipping over the reducer filled with oil can cause oil leakage.

For the geared servo motor, remove the oil before transportation and installation.
Tipping over the reducer filled with oil can cause oil leakage.
Servo motors are available with a reducer designed for general industrial machines and high precision
applications.
Servo motors with an electromagnetic brake are also available.
