Technology controller: Set I component

When the state of the binector selected in U506 switches from log. "0" to "1", the I component of the technology controller is set to the

value parameterized in U505.

With this function it is possible, for example, to use the same signal (binector) to control controller enabling commands and setting of the I

Source for setting value for I component

0 = connector K0000

1 = connector K0001

Source for control bit "Set I component"

0 = binector B0000

1 = binector B0001

Technology controller: Output, limitation

Source for variable positive limit

After multiplication with U508, the contents of the selected connector act as

a positive limit for the technology controller output.

0 = connector K0000

1 = connector K0001

If the selected connector contains a negative value, a negative maximum

value is applied to the output of this limiter stage.

Positive limit for output of technology controller
