■Using the wave output function as PWM
The wave output function is available also as PWM with the shortest pulse width of 80 s.
In addition, since any number of pulses can be analog output by only creating a one pulse wave pattern, it contributes to
reduction of man-hours for program creation.
• Example of creating a wave pattern
Creating a wave pattern with pulse width 80 s, amplitude 5 V, and duty ratio 50%
1.
Set "Output range setting" to 0 to 5 V.

setting]  [Range switching function]
2.
In "Create Wave Output Data", create a wave pattern for one pulse.
Setting item
Wave pattern information
Wave detail setting
The wave monitored on GX Works3 differ from the analog output wave.
3.
Set "Wave output data setting" as follows.
Setting item
CH1 Wave pattern No.
CH1 Wave pattern start address setting
CH1 Wave pattern output repetition setting
CH1 Constant for wave output conversion cycle
4.
Register the wave data and wave output function parameter settings in the analog output module. For how to register
these, refer to the following.
Page 212 Transfer the wave output data
5.
Set D/A conversion enable (0) in 'CH1 D/A conversion enable/disable setting' (Un\G500).
6.
Turn offonoff 'Operating condition setting request' (Un\G70, b9).
7.
Turn on 'CH1 Output enable/disable flag' (Un\G70, b1).
8.
Set 'CH1 Wave output start/stop request' (Un\G462), and start the wave output. After the wave output starts, the
following analog output is generated.
