If output limitation responds, track the
I-component in such a manner that |x|
|y|
Normally the output limitation is set via U369
and acts instantaneously and symmetrically
(same limit values for positive and
negative variables)
If parameterized correspondingly, the 2
limitation ramp-function generators enable
smooth approach or the output limits after
the technology controller has been enabled.
Tv = 0 ==> D-component disabled<1>
Tn = 0 ==> I-component disabled (acts as Tn = )

<3> Priority of the control signals for setting the controller output K0585:
1. "Enable technology controller" = 0
2. "Set I-component" = 1
(However: Setting the I-component also acts on K0585 when
controller is disabled)
Use the simple ramp-function generator on sheet 791,<4>
if you wish to avoid an abrupt switch-in
of the "TeCntr setpoint".
With U360 = 556, the "Setting value I-component" is adopted<5>
when "Enable technology controller" is activated.
