Oil / Water Standards - Mitsubishi Electric MDS-D-SPJ3 Specification Manual

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.
(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.
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
CAUTION
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.
