Design and Installation
j Water and Drip Resistance
Note Protective Structure: Indicated as IP-
Bevel gears will cause a load to be applied in the
thrust direction depending on the structural preci-
sion, the gear precision, and temperature changes.
Provide appropriate backlash or take other mea-
sures to ensure that no thrust load is applied which
exceeds specifications.
Do not put rubber packing on the flange surface. If
the flange is mounted with rubber packing, the motor
flange may separate due to the tightening strength.
When connecting to a V-belt or timing belt, consult the maker for belt selection and tension. A radial
load twice the belt tension will be placed on the motor shaft. Do not allow a radial load exceeding
specifications to be placed on the motor shaft due to belt tension. If an excessive radial load is ap-
plied, the motor shaft may be damaged. Set up the structure so that the radial load can be adjusted. A
large radial load may also be applied as a result of belt vibration. Attach a brace and adjust Position
Driver gain so that belt vibration is minimized.
The Servomotor does not have a water-proof structure. Except for the connector areas, the protec-
tive structure meets the following JEM (The Japan Electrical Manufacturers’ Association) standards:
U Series, 30 to 750 W Conforming to UL/cUL and UE Type Not Conforming to Any Standards: IP-42
U Series, 30 to 750 W Conforming to EC Directives and UE Type Conforming to EC Directives: IP-44
(except shaft penetration point)
U Series, 1 to 2 kW Not Conforming to Any Standards: IP-65 (except shaft penetration point)
U Series, 1 to 2 kW Conforming to EC Directives: IP-55 (including shaft penetration point)
H Series: IP-52
M Series: IP-42
If the Servomotor is used in an environment in which condensation occurs, water may enter inside of
the encoder/resolver from the end surfaces of cables due to motor temperature changes. Either take
measures to ensure that water cannot penetrate in this way, or use water-proof connectors. Even
when machinery is not in use, water penetration can be avoided by taking measures, such as keep-
ing the motor in servo-lock status, to minimize temperature changes.
If machining oil with surfactants (e.g., coolant fluids) or their spray penetrate inside of the motor, in-
sulation defects or short-circuiting may occur. Take measures to prevent machining oil penetration.
The water and drip resistance of the standard cables for U-Series Servomotors of 1 to 2 kW is equiv-
alent to IP-30. Use water-resistance cables for the power cables and encoder cables in locations
subject to contact with water. Use the following recommended products for power cable and encoder
cable connectors when the device is to meet EC directives.
cording to the IEC standard (IEC529: 1989-11).
