SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Sets the 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 this lower limit, this results in fault F07426.
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: Setting to use an arithmetic function for 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: 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 sig-
nal is inverted).
