19  BUILT-IN I/O FUNCTION

19.7  PWM Function

 • Set the pulse width to a value 2 

s more and period to a value 5 s more.

 • Set the value so that pulse width 

 period.

 • The PWM instruction is not executed when a channel number not selected for PWM output in parameters setting is 

specified by the PWM instruction.

An example of a program using the PWM function is explained below.

An example of a program using output Y0 on the CPU module to output one pulse with a delay is explained below.

This program assumes that parameters are set as follows.
CH2, CH3 and CH4 need not be set.

An operation diagram and program are shown below.
