PWMX Output (OUT)
The PWMX OUT (Output) variable defines the physical output that the
PWM instruction controls. This variable is set within the function file
folder when the control program is written and cannot be set by the user
program. The outputs are defined as O0:0/2, O0:0/3 or O0:0/4 as listed
below:
• O0:0.0/2: PWM modulates output 2 of the embedded outputs.
• O0:0.0/3: PWM modulates output 3 of the embedded outputs.
• O0:0.0/4: PWM modulates output 4 of the embedded outputs.
PWMX Decelerating Status (DS)
The PWMX DS (Decel) bit is controlled by the PWM sub-system. It can be
used by an input instruction on any rung within the control program. The
DS bit operates as follows:
• Set (1) - Whenever a PWM output is within the deceleration phase
of the output profile.
• Cleared (0) - Whenever a PWM output is not within the deceleration
phase of the output profile.
PWMX Run Status (RS)
The PWMX RS (Run Status) bit is controlled by the PWM sub-system. It
can be used by an input instruction on any rung within the control
program.
