Setting the controller
Simplified representation of the technology controller
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.
•

Simplified representation of the technology controller
The settings required as a minimum are marked in gray in the function diagram: Interconnect
setpoint and actual values with signals of your choice, set the ramp-function generator and
controller parameters K
You will find information on the following PID controller topics in the Internet at: Manuals for
your converter (Page 334)
● Setpoint value specification: Analog value or fixed setpoint
● Setpoint channel: Scaling, ramp-function generator and filter
● Actual value channel: Filter, limiting and signal processing
● PID controller Principle of operation of the D component, inhibiting the I component and
the control sense
● Enable, limiting the controller output and fault response
