450 List Manual, 04/2018, A5E33838102
Description: Sets the inversion of the system deviation of the free technology controller 2.
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 free technology controller (p11200 = 0).
- increase the motor speed and in so doing, measure the actual value signal (of the free technology controller).
- if the actual value increases with increasing motor speed, then deactivate inversion.
- if the actual value decreases with increasing motor speed, then activate inversion.
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).
Description: Sets the signal source for the actual value of the free technology controller 2.
Description: Sets the smoothing time constant (PT1) for the actual value of the free technology controller 2.
Description: Sets the upper limit for the actual value signal of the free technology controller 2.
