Wave Output Function

This function registers the prepared wave data (digital input value) in the D/A converter module and continuously outputs the
data (analog value) in the set conversion cycle. A faster and smoother control than a program is achieved by the automatic
output of the control wave data registered in the D/A converter module for the analog (torque) control such as pressing
machines and injection molding units. The control can be executed only by registering the wave data to the D/A converter
module. Therefore, the program-less control is available for the repeat control such as the line control, and man-hours for
programming can be reduced.
The wave output function can be used only when "Output mode setting" is set to "Wave output mode" of the basic setting.
This section calls the following items to be set for the wave output function as wave output data.
• Wave data (Page 46 Creating wave data)
• Parameters of the wave output function (Page 49 Setting parameters of the wave output function)
(1) Create wave data.
Wave data can be created with easy
mouse operation from "Create Wave
Output Data" of engineering tool.
(2) Save the wave data to a CSV file or file register.
(3) Register the wave data to the wave data registry area in the
D/A converter module using a function block (FB) for wave data registration.
