FX Series Positioning Controllers Program Examples 9
9-15
4) Program
5) Parameter
Set the positioning parameter No. 16 (mechanical zero point address) to "-130". For other
parameters, refer to Paragraph 9.2.4.
* When performing operation at multi-step speed in the FX
2N
-20GM, set "O0, N0" then use the
program above as it is.
In actual operation, however, the machine performs continuous pass operation, the speed
change points are different from those shown above, and the composite speed is adopted.
Line No.Instruction Description
