2 Parameter detailed description
P17.15=1, output=input 2:
Input 2 is selected as variable selector 1 output.
The example above, P04.03＝P04.02.
P17.15=2, output= input1+ input2:
In the example above, if P04.01＝5Hz, P04.02＝10Hz, the maximum frequency is 50Hz,
then P04.03＝ (10%+20%)×50＝15Hz.
P17.15=3, output= input1- input2:
For example:
P17.11＝4.01, P17.12＝4.02, P17.15＝3, P17.17＝4.03, P04.01＝5Hz, P04.02＝10Hz, the maximum frequency is 50Hz.
Then P04.03＝ (10%−20%)×50＝−5Hz.
P17.15＝4, multiply: Output= (input1×input2)/100
P17.15＝5, divide: Output= (input1×100)/ input2
Because variables are taken as percentages in operation, input 1 and input 2 in formulas above are percentages of the
source maximum omitting “%”. The result is displayed as percentage in P17.34, and the value of P17.34 omits “%” too.
For example:
Multiplication:
P01.02＝50.00 (the maximum frequency is 50.00Hz)
P17.11＝4.16 (variable selector 1 source 1 is P04.06)
P4.16＝50.00 (P04.16 is set to 50.00Hz)
P17.12＝8.17 (variable selector 1 source 2 is AI1 level)
P08.17＝50.0 (P08.17 value range is 0 to 100%. P08.17 is set to 50%.)
P17.15＝4 (multiplication)
P17.17＝4.01 (destination parameter for the variable selector 1 output is P04.01)
Then: in multiply operation, input 1=100%, and input 2=50%
output= (input1×input2)/100.0=(100.0×50.0)/100.0＝50.0
P17.34 displays 50.0
Destination parameter P04.01＝50.00Hz×50.0%＝25.00Hz
Division:
P01.02＝50.00 (the maximum frequency is 50.00Hz)
P17.11＝4.03 (variable selector 1 source 1 is P04.03)
P4.03＝20.00 (P04.03 is set to 20.00Hz)
P17.12＝4.05 (variable selector 1 source 2 is P04.05)
P04.05＝40.00 (P04.05 is set to 40.00Hz)
P17.15＝5 (division)
P17.17＝4.01 (destination parameter for the variable selector 1 output is P04.01)
Then: in division operation, input 1=40%, and input 2=80%
Output=(40.0×100.0)/80.0＝50.0
P17.34 displays 50.0
Destination parameter P04.01＝50.00Hz×50.0%＝25.00Hz
P17.15=6, variable selector 1 is similar to the first order filter with a time constant of P17.16. P17.16 value range is 0.01s
to 99.9s.
P17.15＝7
If input 1changes from 0 to 100.0%, the output linear ramps from 0.0% to 100.0% in time P17.16 set.
