Calculation rule
Q = 1, for (Ax – Min) / (Max – Min) of time period PT
Q = 0, for PT – [(Ax – Min) / (Max – Min)] of time period PT.
Note: Ax in this calculation refers to the actual value Ax as calculated using the Gain and Offset. Min and
Max refer to the minimum and maximum values specified for the range
Special feature.
Generally, the output frequency could be up to 30Hz But the Q3,Q4 of PR-12 type,Q5,Q6 of ELC-18/22/26
(PNP transistor output) CPU,Q7,Q8 of PR-24 could be up to 10KHZ and the property dialog box of PWM
function block setting as follows:
If the special output is selected in the property dialog box of PWM block, then the unit of "periodic time"
will be changed from s:1/100s to s:1/1000s, so if you input 3 (1/1000s) , then its frequency is 1000/3 Hz.
Notes:
1. The periodic time must be no less than 3 ms.
2. If the specific output is selected in the property dialog box of PWM block, then the output pin of PWM
function block cannot be linked as input to other blocks.
3. Q3, Q4 in the above dialog box are exactly corresponding to Q3, Q4 of ELC-12 CPU and Q5,Q6 of
ELC-22/26 and upgraded ELC-18 CPUs
4. Common speed output allow the frequency different for Q3&Q4 of ELC-12 CPU and Q5&Q6 of
ELC-22/26 and upgraded ELC-18 CPUs; But if the high speed ticked in the dialog box then the frequency
