MDS-D-SVJ3/SPJ3 Series Instruction Manual
1-1 Installation of servomotor
1-1-8 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.
