Wave output function
This function registers the previously prepared wave data (digital input values) in the analog output module and performs
consecutive analog output with the set conversion cycle. When analog (torque) control is to be performed, for example, for a
press machine or injection molding machine, it can achieve faster and smoother control than that by programming, by
automatically outputting the control wave registered in the analog output module in advance. In addition, since this control can
be achieved only by registering the wave data in the analog output module, it enables control without programming when
repetitive control such as line control is to be performed, thus reducing the man-hours for programming.
The wave output function is available only when "Wave output mode" is set in "Output mode setting" of the basic setting.
In this section, the following items set in the wave output function are called wave output data. Wave output data can be
created by "Wave output data creating tool" of the module expansion parameter.
• Wave pattern (Page 250 Register the wave pattern)
• Wave output function parameters (Page 254 Setting the wave output function parameters)
(1) Create wave output data
Wave data can be created with
easy mouse operation from "Create
Wave Output Data" of GX Works3.
(2) Write the created wave output data

(3) D/A conversion is sequentially
performed with the set data
and analog output is
