Installation
The service life of the servomotor will be shortened or unexpected problems will occur if the servomotor is
installed incorrectly or in an inappropriate location. Always observe the precautions in this section when
installing a servomotor.
• If the relay cables are connected to the motor, be sure to connect the end for the servomotor's main-circuit
cables before connecting the end for the encoder cable. If the encoder cable's end is connected first, the
encoder may become damaged because of the voltage differences between the Frame Ground (FG) pins
on the servomotor and the grounding terminal of the SERVOPACK.
• If using cables that are not made by Yaskawa, ensure that connector pins and cables are correctly
configured.
• Make sure there is no foreign matter (such as dust and metal chips) in the connector before connecting.
• When handling a servomotor with its cables connected, hold the servomotor or the connectors and cables
will be damaged.
The protective structure of the servomotors is designed with an IP55 rating.
• The servomotor can be used in a location that is subject to water drops, except for the connector and the
section where the shaft passes through.
• Do not use the servomotor in a location that is subject to oil mist.

This refers to the gap where the shaft
protrudes from the end of the motor.
Positive rotation of the servomotor is counterclockwise when viewed from the load.
