Siemens SINAMICS PERFECT HARMONY GH180 - Proportional-Integral-Derivative (PID) Controller

7.11.2 Proportional-Integral-Derivative (PID) Controller
The control has a built-in PID controller available for use as a process control input of the
command generator.
The PID loop is programmable from the user Interface. It is used to incorporate an external
process as an outer control loop to the drive. The PID command set point can be either an
external analog input or an internal set point. The PID feedback is always from an analog input.
The proportional, integral, and derivative gains, as well PID output limits, are programmable.
The PID is depicted in the following 󹪝gure.

Con󹪝guring the PID Controller
1. Select the PID output as the speed demand for the system by setting SOP
󹪞ag RawDemandPid_0 to true.
2. The PID command feedback source is 󹪝xed from analog input #2. You can use any of the
available analog inputs within the system, but you must designate it as analog input #2 in the
setup menu. Refer to Analog Input #2 Menu (4170) in Section Options for Auto Menu (4) of
Chapter Parameter Assignment / Addressing.
3. The PID command has two possible sources: analog input #1 or the PID set point menu
(4410). Select the source using SOP 󹪞ag PidMenu_0:
– Set 󹪞ag to true to select the PID set point menu as the source.
– Set 󹪞ag to false to select analog input #1 as the source.
4. Con󹪝gure analog input #1 source from Analog Input #1 Menu (4100) in Section Options for
Auto Menu (4) of Chapter Parameter Assignment / Addressing.
Parameters for the PID Controller
Refer to PID Select Menu (4350) in Section Options for Auto Menu (4) of Chapter Parameter
Assignment / Addressing for parameters to set the PID controller.
