2. An analog value of 300 (range 0...1000) as the value for
Ax must be modulated to a digital signal string. The user-
defined T (periodic time) parameter is 10 seconds. At the
digital output of the PWM function the digital signal string
is 3 seconds high, 7 seconds low, 3 seconds high, 7
seconds low and continues in that pattern as long as
parameter "En" = high.
Calculation rule
Q = 1, for (Ax - Min)/ (Max - Min) of time period T, when Min
< Ax < Max
Q = 0, for PT - [ (Ax - Min) / (Max - Min) ] of time period T.
Note
Ax in this calculation refers to the actual value Ax as calculated
using the Gain and Offset.
Setting the Par Parameter
The following illustration shows the view in programming
mode that corresponds to the first example:
B1
Min=+00000
Max=+01000
A=+01.00
Use the
and P parameters. For each digit of a value, use the
keys to scroll through value choices. Use the
navigate to the second screen from the last line of the first
screen, and the
second screen to the first screen. Use the OK key to accept
changes.
