2.2 List of parameters
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).
Description: Display and connector output for the scaled actual value signal of the technology controller.
Dependency: Refer to: p2264, p2265, r2266, p2267, p2268, p2269, p2270, p2271
Description: Displays the system deviation between the setpoint and actual value of the technology controller.
Dependency: Refer to: p2263
Description: Sets the time constant for the differentiation (D component) of the technology controller.
Note: p2274 = 0: Differentiation is disabled.
