CU240D-2_PN

CU240D-2_PN_F
Min
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:
1:
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).
