15.ABSOLUTE POSITION DETECTION SYSTEM

(3)Sequence program - 2-axis control

The following program is a reference example for creation of an ABS sequence program for the second axis (Y axis) using a single A1SD75 module. Create a program for the third axis in a similar manner.

(a)Y-axis program

Refer to the X-axis ABS sequence program and create the Y-axis program.

Assign the X inputs, Y outputs, D registers, M contacts, T timers and C counters of the Y axis so that they do not overlap those of the X axis.

The buffer memory addresses of the A1SD75 differ between the X and Y axes. The instructions marked *1 in the program of Section 15.8.3 (2), (c) should be changed as indicated below for use with the Y axis:

(b)Data set type home position return

Arrange the data set type home position return programs given in Section 15.8.3 (2), (f) in series to control two axes.

Refer to the X-axis data set type home position return program and create the Y-axis program. Assign the X inputs, Y outputs, D registers, M contacts and T timers of the Y axis so that they do not overlap those of the X axis.

The buffer memory addresses of the A1SD75 differ between the X and Y axes.
