EA180 Series Servo Drive Users Manual 2.5.2 Schematic diagram of installation 16 Item Description Antirust treatment Before installation, please wipe off the "rust inhibitor" on the extension of the servo motor shaft before relevant antirust treatment. Notes for encoders The shaft extension shall not be impact during installation, otherwise the encoder inside will be cracked. Pulley installation When installing pulleys on a servo motor shaft with a keyway, use screw holes at the shaft end. In order to install the pulley, first insert the double-headed nail into the screw hole of the shaft, use a washer on the surface of the coupling end, and gradually fasten the pulley with a nut.
For servo motor shaft with a keyway, install it with the screw hole at shaft end. For a shaft without keyway, wear coupling or similar methods can be adopted. When the pulley is removed, a pulley remover should be used to prevent impact on the bearing. In order to ensure safety, a protective cover or similar device shall be installed in the rotating area. Screw Centering Washer Flange coupling Please use a coupling to connect the device with the machine and keep the axis of the servo motor in a straight line with that of the machinery. The radial runout of the coupling should not be greater than 0.03 mm.
If centering is not sufficient, vibration will occur, which may damage bearings, encoders, etc. Installation direction Servo motor can be installed in a horizontal or vertical direction. Please do not install the device obliquely, otherwise it may cause wearing of motor bearing. Countermeasu res for oil and water For use in places with water dripping, please confirm the protection rating of the servo motor before use (except the shaft penetration part). For use in places where oil drips to the shaft penetration part, please be sure to use servo motors with oil seals. Service conditions for servo motors with oil seals:
Please make sure that the oil level is lower than the lip of the oil seal during use. Please use the oil seal in a state where the oil spatter can be kept in a good degree. When the servo motor is installed vertically upward, please be careful to prevent oil accumulation on the oil seal lip. Flange face Shaft through part refers to the gap at the extending part of shaft from the motor end face Shaft end Cable stress condition Do not bend the cables excessively or apply tension to them, especially for the 0.14 mm2 or 0.2 mm2 core wires of the encoder signal cables, which is very thin. So please do not stretch them too tightly during wiring and use.
When installing in the tow chain, high-flexibility tow chain cables must be selected. Connector handling For the connector part, please pay attention to the following: When connecting a connector, please make sure that there is no foreign matter such as garbage or metal debris in the connector. When connecting the connector to the servo motor, be sure to connect from the side of the main circuit cable of the servo motor first, and the main cable must be reliably grounded. Otherwise, the encoder may fail due to the potential difference with PE. When wiring, please make sure the pins are arranged correctly. The connector is made of resin.
Do not apply impact to the connector, otherwise it may be damaged. Always hold the main body of the servo motor during handling while the cables remain connected. Otherwise, the connector may be damaged or the cables may be broken. If a cable needs to be bent, due care should be taken during wiring so as not to cause pressure or tension on the connector, otherwise damage or poor contact of the connector may be caused.
