(C**.2) is
formed dependent on the direction over the time. The rise speed is tan

t = 100 %/tin.
In position tin = ProG the integral speed is progressive so that setpoints set manually can be
set fast and still with a high resolution when switching with the keys. The output of the integrator
is saved in a non--volatile memory when bAtt = YES is set.
The integrator can be tracked to the value applied at U
N
(C**.3) by the control signal N = Hi
(C**.4). 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
output limit LiA cannot be set greater than the maximum output limit LiE and vice versa.
At

Δ
=Lo the integrator acts as an analog memory.
