• Set (1) - Whenever a PWM output is within the acceleration phase of
the output profile.
• Cleared (0) - Whenever a PWM output is not within the acceleration
phase of the output profile.
PWM Profile Parameter Select (PP)
Element Description
PP - Profile Parameter Select
The PWM PP (Profile Parameter Select) selects which component of the
waveform is modified during a ramp phase:
• Set (1) - selects Frequency
• Cleared (0) - selects Duty Cycle
The PWM PP bit cannot be modified while the PWM output is running/
enabled. See PWM ADD on page 158 for more information.
PWM Idle Status (IS)
Element Description Address
IS - PWM Idle Status PWM:0/IS bit
The PWM IS (Idle Status) is controlled by the PWM sub-system and
represents no PWM activity. It can be used in the control program by an
input instruction.
• Set (1) - PWM sub-system is in an idle state.
• Cleared (0) - PWM sub-system is not in an idle state (it is running).
