PWMX Idle Status (IS)
The PWMX 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).
PWMX Error Detected (ED)
The PWMX ED (Error Detected) bit is controlled by the PWM sub-system.
It can be used by an input instruction on any rung within the control
program to detect when the PWM instruction is in an error state. If an
error state is detected, the specific error is identified in the error code
register (PWMX:0.ER).
•
Set (1) - Whenever a PWM instruction is in an error state.
•
Cleared (0) - Whenever a PWM instruction is not in an error state.
PWMX Normal Operation (NS)
The PWMX NS (Normal Operation) bit is controlled by the PWM
sub-system. It can be used by an input instruction on any rung within the
control program to detect when the PWM is in its normal state. A normal
state is defined as ACCEL, RUN, or DECEL with no PWM errors.
•
Set (1) - Whenever a PWM instruction is in its normal state.
•
Cleared (0) - Whenever a PWM instruction is not in its normal state.
