Referencing is the process of setting a Servo Axis position in reference to a stationary object such as a sensor or a hard stop (travel limit). Any time the mechanical link between the servo motor and the object that the servo motor is moving has been violated (disconnected, jumped teeth), the servo motor will need to be referenced. If a servo motor is not working correctly, it may need to be replaced (please see the Replacing an MI Drive topic in the Troubleshooting Guide for more information).
The referencing process begins by moving the servo axis towards the stationary object used for determining the servo axis position. When the object is located, the servo motor will then move to the reference end position based on the capture position of the stationary object. When the servo axis reaches the reference end position, the motor will disable and the servo axis’ position will be set. Once the position has been set, the servo axis will enable and reposition itself to the reference end position completing the reference process.
Settings for referencing each servo axis can be found on the Servo Drive Data Page.
A a summary of all servos and their reference positions can be viewed in the Servo Reference Positions topic in this manual.
