Description: Setting to invert the fault signal of the technology controller.
The setting depends on the type of control loop.
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 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).
