MDS-D/DH Series Specifications Manual
4-1 Servomotor
4 - 5
4-1-5 Oil / water standards
(1) The motor protective format uses the IP type, which complies with IEC Standard. (Refer to the section “2-1-1
Specifications list".) 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.
