The MPL-A1520U-HJ72AA servo motor is a low-inertia servo motor that has been designed by Allen-Bradley/Rockwell Automation and included in its MPL series of premium permanent magnet servo motors. This servo motor operates with a voltage rating of 200 Volts and it comes with a frame size of 63 millimeters. This servo motor can operate at speeds of up to 7000 RPM, one of the highest speeds supported by the servo motors in the MPL series. This servo motor comes with a circular connector that is rotatable up to 180 degrees, making it easy and flexible to locate and connect. The installation of the Allen-Bradley/Rockwell Automation MPL-A1520U-HJ72AA low-inertia servo motor should start by inspecting the device and checking that all its components are present and undamaged. The users also need to determine if the servo motor is fully compatible with their system before selecting and installing it. When the servo motor is connected and mounted, both connectors need to be grasped by their housing and they need to be slowly rotated to the outside of the motor. The force of this rotation needs to be applied directly to the connectors, not to the cable. Tools are not recommended for rotating the connector.
The Allen-Bradley/Rockwell Automation MPL-A1520U-HJ72AA MPL series low-inertia servo motor does not include a built-in brake. The function of a brake in an MPL servo motor is to detect the voltage rating that is being applied to the coils and to stop any action if this rating exceeds the maximum system rating. Without this feature, the users need to make sure the proper voltage rating is being applied to the motor to avoid malfunctioning and component damage, and they may need to install an external servo motor brake. The Allen-Bradley/Rockwell Automation MPL-A1520U-HJ72AA low-inertia servo motor comes with a shaft key that enables the motor to use a shaft seal which provides a strong degree of protection against liquids. The life of the motor can be extended by inspecting it periodically for signs of wear that may indicate the motor needs maintenance, and this will prevent severe device damage if worn parts are repaired or replaced immediately.
