FX3U-20SSC-H positioning Learning to Use the FX Family for Positioning Control
FX Positioning Control Systems 4 - 67
4.6.5 Program example
The following program uses buffer memory communication to perform JOG positioning, 1-speed posi-
tioning, and table operation control. The XY-table created in the previous section can be used in this
example. For this example, FX Configurator-FP should be used to specify the servos, change the max-
imum speed, and to set the zero return mode as described in section 4.6.2.
The ladder program is to be used with an FX
3U(C)
PLC and MR-J3-B servo system. Without these com-
ponents, the program cannot be tested. Input points from the PLC include:
Inputs

X001 X-axis Forward rotation JOG(+) X006 STOP command
X002 X-axis Reverse rotation JOG(-) X007 Error reset
X003 X- and Y-axis Zero return X010 X-axis Reverse rotation limit
