Parameters
List of Parameters
r2272 CO: Technology controller actual value scaled / Tech_ctrl act scal
Access level: 2
Can be changed: -
Units group: 9_1
Min
- [%]
Description: Displays the scaled actual value signal of the technology controller.
Dependency: Refer to: p2264, p2265, r2266, p2267, p2268, p2269, p2270, p2271
r2273 CO: Technology controller error / Tec_ctrl error
Access level: 2
Can be changed: -
Units group: 9_1
Min
- [%]
Description: Displays the error (system deviation) between the setpoint and actual value of the technology controller.
Dependency: Refer to: p2263
p2274 Technology controller differentiation, time constant / Tec_ctrl D comp T
Access level: 2
Can be changed: U, T
Units 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
Units 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
Units 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.
