Pulse Outputs)
A PWM (Pulse Width Modulation) pulse can be output with a specified duty ratio. The duty ratio is the
ratio of the pulse's 'ON time and OFF time in one pulse cycle.
Use the PWM(891) instruction to generate PWM pulses from a pulse output.
The duty ratio 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.
