p2306 Technology controller system deviation inversion / Tec_ctr SysDev 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 system deviation of the technology controller.
The setting depends on the type of control loop.
Value: 0: No inversion
1: Inversion
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 with increasing motor speed, then the inversion should be switched out.
- if the actual value decreases with increasing motor speed, then the inversion should be set.
If value = 0:
The drive reduces the output speed when the actual value rises (e.g. for heating fans, intake pump, compressor).
If value = 1:
The drive increases the output speed when the actual value increases (e.g. for cooling fans, discharge pumps).

Access level: 2 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: 7959
Min:
0.000
Max:
1000.000
Factory setting:
1.000
Description: Sets the lower value for the adaptation of proportional gain Kp for the technology controller.
Dependency: See also: p2310, p2312, p2313, p2314, p2315, r2316
CAUTION
The upper value must be set higher than the lower value (p2312 > p2311).
Note
Kp adaptation is activated with p2252.7 = 1.
