3.2.3 Precautions on servo motor installation
Item
Description
Anticorrosive
Before starting installation, thoroughly remove the anticorrosive paint that coats the end of
motor shaft.
Alignment
Align the shaft of the servo motor with the shaft of the equipment, and then couple the shafts.
Orientation
Servo motor can be installed either horizontally or vertically.
Handing oil and
water
If the servo motor is used in a location that is subject to water drops, make sure of servo motro
protective specifications.
If the servo motor is used in a location that is subject to water or oil mist, use a servo motor
with oil seal.
Precautions on using servo motor with oil seal
·The oil surface must be under the oil seal lip.
·Use an oil seal in favorably lubricated condition.
·When servo motor is installed vertically, be sure that oil will not stay in the oil seal lips.
Cable stress
Make sure there are no bends or tension on the power cables.
Be especially carefully to wire signal cables so that they are not subject to stress because the
core wires are very thin at only 0.2 to 0.3mm.
Connectors
Observe the following precautions:
·Make sure there is no foreign matters such as dust and metal chips in the connector before
connecting.
·when the connectors are connected to the motor, be sure to connect the end of servo motor
circuit cables before connecting the encoder cable’s end. If the encoder cable’s is connected,
the encoder may be damaged because of the voltage differences between PE.
·Make sure of the pin arrangement.
·Do not apply shock to resin connectors. Otherwise, they may be damaged.
·When handling a servo motor with its cable connected, be sure not to apply stress on the
connector. The connector may be damaged by stress.
