Oil or water

Servomotor 

(1) A format based on IEC Standards (IP types) is used as the motor 

protective format. However, these Standards are short-term performance 
specifications. They do not guarantee continuous environmental 
protection characteristics. Measures such as covers, etc., must be 
provided if there is any possibility that oil or water will fall on the motor, or 
the motor will be constantly wet and permeated by water. Note that the 
motor’s IP-type is not indicated as corrosion-resistant.  

 
 
 
(2)  When a gear box is installed on the servomotor, make sure that the oil level height from the center of 

the shaft is higher than the values given below. Open a breathing hole on the gear box so that the 
inner pressure does not rise.

(3)  When installing the servomotor horizontally, set the power cable and detector cable to face downward. 

 When 

installing vertically or with an inclination, provide a cable trap.

1.  The servomotors, including those having IP67 specifications, do not have a 

completely waterproof (oil-proof) structure. Do not allow oil or water to 
constantly contact the motor, enter the motor, or accumulate on the motor. Oil 
can also enter the motor through cutting chip accumulation, so be careful of 
this also. 

2.  When the motor is installed facing upwards, take measures on the machine 

side so that gear oil, etc., does not flow onto the motor shaft.  

3.  Do not remove the detector from the motor. (The detector installation screw is 

treated for sealing.)
