tr = off,1 to 9984 s tracking time (ramp)
The integral of the variable input value E (polarity and value) is formed over the time t. The rise
speed at constant E is tanα = ΔA/Δt = E/tin.
The integrator can be tracked to the value applied at U
N
(C**.2) by the control signal N = high
(C**.3). The tracking time is specified by the private parameter tr .

Integration and tracking are only possible within the limits set with LiA and LiE. The minimum
value LiA may not be set greater than the maximum value LiE and vice versa.
At E = 0 and N = low the integrator acts as an analog memory.
