If the value of the parameter
is set to 100% a change of
100.00 118 10% in the error value
causes the controller output
to change by 10%.
If this parameter is set to
1,00 second a change of
1.00 119 10% in the error value
causes the controller output
to change by 10.00%/s.
If this parameter is set to
1,00 second a change of
0.00 132 10% in the error value during
1.00 s causes the controller
output to change by 10.00%.

Min and Max are the process
values corresponding to 0%
and 100% respectively
(scaled linearly in between).
