p2274 Technology controller differentiation time constant / Tec_ctrl D comp T
Access level: 2
Can be changed: U, T
Unit group: -
Min
0.000 [s]
Description: Sets the time constant for the differentiation (D component) of the technology controller.
Note: p2274 = 0: Differentiation is disabled.
p2280 Technology controller proportional gain / Tec_ctrl Kp
Access level: 2
Can be changed: U, T
Unit group: -
Min
0.000
Description: Sets the proportional gain (P component) of the technology controller.
Note: p2280 = 0: The proportional gain is disabled.
p2285 Technology controller integral time / Tec_ctrl Tn
Access level: 2
Can be changed: U, T
Unit group: -
Min
0.000 [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.
p2286[0...n] BI: Hold technology controller integrator / Tec_ctr integ hold
Access level: 3
Can be changed: T
Unit group: -
Min
-
Description: Sets the signal source to hold the integrator for the technology controller.
p2289[0...n] CI: Technology controller pre-control signal / Tec_ctr prectr_sig
Access level: 3
Can be changed: U, T
Unit group: -
Min
-
Description: Sets the signal source for the pre-control signal of the technology controller.
