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

General, the output frequency could be up to 30Hz But the Q5,Q6 of ELC-18DC-D/DA-TN type

(PNP transistor output) CPU could be up to 333 Hz 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.

Note s :

1. T he 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. Q5 , Q6 of ELC-18DC-DA-TN & ELC-18DC-D-TN on the above dialog box are exactly

corresponding to Q3 , Q4 of ELC-12DC-D/DA- TN ( PNP) CPUs
