Note: the LinearMotion FB in this image is old. However, the main parameter has not changed.
In the image to the left, the 'top' LinearMotion FB is red. It is connected it to the top (Y1) input of the Graph FB, and the 'bottom' LinearMotion FB is connected to the Xaxis.
SETTINGS
The dialog for the 'top' LinearMotion FB is open. The Machine Angle = +30
MasterMachineAngle = 120
GRAPH CONNECTIONS:
XAXIS 'bottom' Graph connection
The 'bottom' LinearMotion FB is connected to the Xaxis of the Graph FB.
The phase of the 'bottom' LinearMotion FB is '0'.
Therefore, the motion value at the outputconnector of the 'bottom' LinearMotion FB, and the input to the Xaxis of the Graph FB is:
= MMA
= 120
YAXIS – 'top' Graph connection
The 'top' LinearMotion FB is connected to the Y1Axis of the Graph FB.
The phase of the 'top' LinearMotion FB is +30
Therefore, the motion value at the outputconnector of the 'top' LinearMotion FB, and the input to the Y1Axis of the Graph FB is: =
MMA + Phase =
120 + 30 = 150
