1. If there is more than one identical label in a program, an error will result (“Duplicate labels are defined”).
2. If the number of PFORK branches and the number of labels are different, an error will result.
3. Use a space or a comma (,) to divide a label of a PFORK command. A space and a comma can be used
together.
(Example) PFORK LABEL1 LABEL2, LABEL3 LABEL4;
1.2.2 Controlled Axes
J Axis Names
With the MP-series Machine Controller, any axis name can be set using a maximum of eight
characters. The axis names are set on the Group Definition window of the MPE720. The charac-
ters that can be used in axis names and the default axis names are shown in the following table.
Usable Characters 0 to 9, A to Z, a to z
Example of Axis Names [AXIS1] [X1] [CONV1]
Default Axis Names With 4-axis designation
[A1] [B1] [C1] [D1]
With 8-axis designation
[A1] [B1] [C1] [D1] [E1] [F1] [G1] [H1]
1. An axis name must contain from one to eight alphanumeric characters, and must be enclosed in [ ].
2. The same axis name cannot be set for more than 1 axis.
3. If the axis names set on the Group Definition window are different from those designated in the motion
program, an error will result (“Axis name error”).
J Coordinate Words
In this manual, the combination of an axis name and the signed travel distance or coordinate val-
ue that follows it is called a “coordinate word.”
The meanings of the coordinate words used in this system are shown in the following table.
Designation Method for Coordinate Words Meaning
Axis Name [X1], [Y1] [AXIS] Designation of the name of the axis to be
moved
Travel Distance or
Coordinate Value Direct designation: 123.456
Indirect designation: MW0100 Coordinate value of the designated axis or
incremental move distance
