10.000 [s]
Description:
Sets the integral time (I component, integrating time constant) of the technology controller.
NOTICE
The following applies for p2251 = 0:
If the output of the technology controller lies within the range of a suppression (skip) bandwidth (p1091 ... p1094,
p1101) or below the minimum speed (p1080), the integral component of the controller is held so that the controller
temporarily works as a P controller. This is necessary in order to prevent the controller from behaving in an unstable
manner, as the ramp-function generator switches to the parameterized up and down ramps (p1120, p1121) at the
same time in order to avoid setpoint steps. This state can be exited or avoided by changing the controller setpoint or
by using the start speed (= minimum speed).
Note
When the controller output reaches the limit, the I component of the controller is held.
p2285 = 0:
The integral time is disabled and the I component of the controller is reset.
