Description: Lower limit for the actual value signal of the technology controller.
Dependency: Refer to: p2264, p2265, p2271
Refer to: F07426
Notice: If the actual value falls below the parameter value, this results in fault F7426.
Description: Scaling factor for the actual value of the technology controller.
Dependency: Refer to: p2264, p2265, p2267, p2268, p2271
Note: For 100%, the actual value is not changed.
Description: Selects an arithmetic function that should be applied to the actual value signal of the technology controller.
Value: 0: No function
1: Root function (root from x)
2: Square function (x * x)
3: Cube function (x * x * x)
Dependency: Refer to: p2264, p2265, p2267, p2268, p2269, p2271
Description: Selects the inversion of the actual value signal of the technology controller. This depends on the type of the actual
value sensor.
Value: 0: No inversion
1: Inversion of technology controller 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.
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 with increasing motor speed, then the inversion should be switched out.
- if the actual value decreases with increasing motor frequency, then the inversion should be set.
