Function description
Function diagram
The technology controller is implemented as a PID controller (controller with proportional,
integral, and derivative action).
①
The inverter uses the start value when all the following conditions are simultaneously satisfied:
•
The technology controller supplies the main setpoint (p2251 = 0).
•
The ramp-function generator output of the technology controller has not yet reached the start value.
