2.2 List of parameters
Description: Sets the ramp-up time for the free technology controller 0.
Dependency: Refer to: p11058
Note: The ramp-up time is referred to 100 %.
Description: Sets the ramp-down time for the free technology controller 0.
Dependency: Refer to: p11057
Note: The ramp-down time is referred to 100 %.
Description: Display and connector output for the setpoint after the ramp-function generator of the free technology controller 0.
Description: Sets the inversion of the system deviation of the free technology controller 0.
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).
