Displays the PWM Output frequency or ON duty error status. When error code 101 (parameter error) is stored in system variable #L_IOStatus[1], you can verify the error status using the value in system variable (#L_ExIOSpParmErr). The watch bit will differ, depending on the CH to which you allocate the PWM output.
When changing Special I/O parameters, and the ON duty value is set outside the valid range, operations continue by using parameters set up to that point.
However, since an invalid value is stored in the system, make sure you change it to a valid value.
If you restart the LT with invalid values (go off-line, reset, or turn the power OFF), operations will use initial parameter values set up in GP-Pro EX.
