p2270 Technology controller actual value function / Tec_ctr ActVal fct
Access level: 3 Calculated: - Data type: Integer16
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: 7958
Min:
0
Max:
3
Factory setting:
0
Description: Setting to use an arithmetic function for the actual value signal of the technology controller.
Value: 0: Output (y) = input (x)
1: Root function (root from x)
2: Square function (x * x)
3: Cube function (x * x * x)

p2271 Technology controller actual value inversion (sensor type) / Tech_ctrl act inv
Access level: 3 Calculated: - Data type: Integer16
Can be changed: T Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: 7958
Min:
0
Max:
1
Factory setting:
0
Description: Setting to invert the actual value signal of the technology controller.
The inversion depends on the sensor type for the actual value signal.
Value: 0: No inversion
1: Inversion actual value signal
CAUTION
If the actual value inversion is incorrectly selected, then the closed-loop control with the technology controller can
become unstable and can oscillate!
Note
The correct setting can be determined as follows:
- inhibit the technology controller (p2200 = 0).
- increase the motor speed and in so doing, measure the actual value signal of the technology controller.
--> If the actual value increases as the motor speed increases, then p2271 should be set to 0 (no inversion).
--> If the actual value decreases as the motor speed increases, then p2271 should be set to 1 (the actual value signal
is inverted).
