Mitsubishi Electronics MR-J2S- A instruction manual Sequence program 2-axis control, Dtop

15.ABSOLUTE POSITION DETECTION SYSTEM

(4)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 A1SD71 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 A1SD71 differ between the X and Y axes. The instructions marked *1 in the program of Section 15.8.1 (3), (c) should be changed as indicated below for use with the Y axis:

[FROMP H0001 K7872 D8 K1]	[FROMP H0001 K7892 D8 K1]
[DFROP H0001 K7912 D9 K1]	[DFROP H0001 K7922 D9 K1]
[DTOP H0001 K41 D3 K1]	[DTOP H0001 K341 D3 K1]
[Program configuration]

X-axis ABS sequence program (Program in Section 15.8.1 (3), (f))

Y-axis ABS sequence program

(Refer to the X-axis program and write the Y-axis program)

(b)Data set type home position return

Arrange the data set type home position return programs given in Section 15.8.1 (3), (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. The instructions marked *1 in the program of Section 15.8.1 (3), (f) should be changed as indicated below for use with the Y axis:

[DTOP	H0001	K7912 D9 K1]	[DTOP	H0001	K7922 D9 K1]
[DTOP	H0001	K41 D9 K1]	[DTOP	H0001	K341 D9 K1]

[Program configuration]

X-axis data set type home position return program (Program in Section 15.8.1 (3), (f))

Y-axis data set type home position return program (Refer to the X-axis program and write the Y-axis program)
