Processing details
This instruction outputs a PWM waveform of the specified CH (refer to the following).
• ICPWM1: CH1
• ICPWM2: CH2
The PWM waveform with the ON time ((s1)) and the cycle time ((s2)) is output from the coincidence output No.1 signal during
the ICPWM instruction execution. The output of the PWM waveform starts from OFF.
