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: FAQ
(http://support.automation.siemens.com/WW/view/en/92556266)
● 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

Remark
BI: Technology controller enable (factory setting: 0)
1 signal:
Technology controller is enabled.
CO: Technology controller output signal
To interconnect the main speed setpoint with the technology controller output, set
p1070 = 2294.
CI: Technology controller setpoint 1 (factory setting: 0)
Setpoint for the technology controller.
Example:
p2253 = 2224: The inverter interconnects the fixed setpoint p2201 with the setpoint
of the technology controller.
p2220 = 1: The fixed setpoint p2201 is selected.
CI: Technology controller actual value (factory setting: 0)
Technology controller actual value.
Technology controller ramp-up time and ramp-down time (factory setting: 1 s)
Technology controller differentiation time constant T
The differentiation improves the rise time for very slow controlled variables, e.g. a
temperature control.
Technology controller proportional gain K
Technology controller integration time (integral time) T
