Further information about the following PID controller topics is available in the Internet:
● Setpoint 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

Parameter
In the factory setting, the output of the technology controller is limited to ± maximum speed. You must
change this limit, depending on your particular application.
Example: The output of the technology controller supplies the speed setpoint for a pump. The pump
should only run in the positive direction.

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
Limiting the output of the technology controller
Remark
CI: Technology controller maximum limiting signal source (factory setting: 1084)
CI: Technology controller minimum limiting signal source (factory setting: 2292)
