1) Turns ON the initial data setting request flag
(RY79).
4) Reads out the initial data setting complete flag
(RX79).
5) With the initial data setting complete flag (RX79)
ON, writes start No. to the Axis 1 positioning start
No. setting area (RWw0) and Axis 2 positioning
start No. setting area (RWw8).
7) Turns OFF the initial data setting request flag
(RY79).
10) Reads out the initial data setting complete flag
(RX79) and the remote station READY flag
(RX7B).
11) With the initial data setting complete flag (RX79)
OFF and the remote station READY flag (RX7B)
ON, turns ON the Axis 1 servo ON flag (RY20)
and Axis 2 servo ON flag (RY40).
13) Turns ON the Axis 1 positioning start flag (RY10)
and Axis 2 positioning start flag (RY11).
