When the PWM2 instruction input changes from off to on, M0200 turns on and pulses with the width ratio configured by D0101 are
output. If the value of D0101 changes during pulse output, pulses are output with the width ratio based on that value.
When the PWM2 instruction input changes from on to off, M0200 turns off and M0201 turns on at the same time.
The changes from the initialization input are not reflected while the PWM2 instruction input is on. If you wish to initialize the data
registers with the initialization input, turn the initialization input on after turning off the input.
