• Set (1) - Whenever the PWM instruction is within the run phase of
the output profile.
• Cleared (0) - Whenever the PWM instruction is not within the run
phase of the output profile.
PWMX Accelerating Status (AS)
Element Description Address
AS - Accelerating Status PWM:0/AS bit
The PWMX AS (Accelerating Status) bit is controlled by the PWM
sub-system. It can be used by an input instruction on any rung within the
control program. The AS bit operates as follows:
• 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.
PWMX Profile Parameter Select (PP)
Element Description
PP - Profile Parameter Select
The PWMX 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 PWMX PP bit cannot be modified while the PWM output is running/
enabled. See PWMX ADD on page 166 for more information.
