13-1 PWM Outputs (Variable-duty-factor
Pulse Outputs)
PWM outputs can be used only with the CP2E N/S
-type CPU Unit with transistor outputs.
A PWM (Pulse Width Modulation) pulse can be output with a specified duty factor. The duty factor is the
ratio of the pulse
’
s ON time and OFF time in one pulse cycle. Use the PWM instruction to generate
PWM pulses from a built-in output. The duty factor can be changed during pulse output.
z
Application example
•
Controlling temperature on a time-proportional basis using the PWM output.
•
Controlling the brightness of lighting.
* The duty factor accuracy declines significantly at high frequencies because of limitations in the output circuit at
high frequencies.
Additional Information
For N
3
0/40/60 CPU Units, the output indicator of terminal 01 on terminal block CIO100 is always
lit during PWM output.
