When the wave output function is used as PWM
The wave output function can also be used as PWM with the minimum pulse width of 20s.
Also the man-hours for programming can be reduced because necessary numbers of pulses can be output in analog by
creating a wave pattern only for one pulse.
■Example of wave pattern creation
When a wave pattern with a pulse width of 20s, amplitude of 5V, and duty ratio of 50% is created
1.
Set "Output range setting" to "0 to 5V".

2.
Create a wave pattern for one pulse in "Create Wave Output Data".
Setting item
Wave pattern information
Wave details setting
The wave pattern to be output in analog differs from the one to be monitored on the engineering tool.
3.
Configure "Wave output data setting" as shown below.
Setting item
Wave pattern No. for CH1
Wave pattern start address setting for CH1
Wave pattern output repetition setting for CH1
Constant for wave output conversion cycle for CH1
4.
Register the wave data and parameters of the wave output function to the D/A converter module. For how to register the
wave data and parameters, refer to the following. ( Page 58 Registering wave output data)
