System Design and Installation
3,000-r/min Servomotors (1 to 5 kW): IP67 (except for through-shaft parts). Models are also avail-
able with IP67 ratings that include through-shaft parts.
3,000-r/min Flat-style Servomotors (100 W to 1.5 kW): IP55 (except for through-shaft parts). Mod-
els are also available with IP67 ratings that include through-shaft parts.
1,000-r/min Servomotors (300 W to 5.5 kW): IP67 (except for through-shaft parts). Models are also
available with IP67 ratings that include through-shaft parts.
1,500-r/min Servomotors (450 W to 15 kW): IP67 (except for through-shaft parts). Models are also
available with IP67 ratings that include through-shaft parts.
The standard cable conforms to IP30. When selecting an IP67-rated Servomotor for use in a wet envi-
ronment, install waterproof connectors for the power and Encoder Cables. The recommended connec-
tors are the same as for the EC Directives, listed in the tables above.
H Oil Seals
If the Servomotor is to be used in a location where it may be exposed to oil or grease, select an
IP67-rated Servomotor or a Servomotor with an oil seal.
H Other Precautions
• Do not apply commercial power directly to the Servomotor. The Servomotors run on synchronous
AC and use permanent magnets. Applying commercial power directly will burn out the motor coils.
• Take measures to prevent the shaft from rusting. The shafts are coated with anti-rust oil when
shipped, but anti-rust oil or grease should also be applied when connecting the shaft to a load.
• Absolutely do not remove the encoder cover or take the motor apart. The magnet and the encoder
are aligned in the AC Servomotor. If they become misaligned, the motor will not operate.
