3-2-5 Oil and waterproofing measures
①
A format based on IEC Standards (IP types) is displayed as the
servomotor protective format (refer to "10-2-1 List of Specifications.").
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
IP-type motors are 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. An oil seal is provided only on the HA-FF
†
C-UE and
HC-MF
†
-S15 of the HA-FF and HC-MF Series.

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, 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. The standard HC-MF Series and HA-FF Series servomotors do not have an
oil seal. Provide a seal on the gear box side so that lubricating oil, etc., does
not enter the servomotor.
4. Do not remove the detector from the motor. (The detector installation screw
is treated for sealing.)
