1-1-6 Oil/water standards
[1] The motor protective format uses the IP type, which complies with IEC
Standard. However, these Standards are short-term performance
specifications. They do not guarantee continuous environmental
protection characteristics. Measures such as covers, etc., must be
taken if there is any possibility that oil or water will fall on the motor,
and 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 on an inclination, provide a cable trap.

CAUTION
1. The servomotors, including those having IP65 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.)
