Open-Loop Fan; Basic Commissioning; Pid Controller; Open-Loop Pump - Siemens Sinamics G120 Operating Instructions Manual

Wizards
The output voltage can be increased (boosted) in the Inverter using the boost function.
The Boost settings wizard guide the user through the correct setting of the boost function.

Open-loop fan

This is a basic fan application where the fan is under the control of the Inverter.
The system comprises of the following components:
● Control Module
● Power Module
● Motor
● Fan
● Belt monitoring sensor (optional)
● Motor temperature sensor (optional)

Basic commissioning

The basic commissioning of the Inverter and motor comprises a number of processes. The
processes are as follows:
● Quick commissioning
● Vector control mode
● Calculation of motor and control data
The wizard will guide the user through the basic commissioning process by presenting a
number of screens where the user can choose the necessary options and values to
commission the Inverter and motor. At the conclusion of the basic commissioning process,
the data can be saved to the Inverters memory.

PID controller

Closed-loop control is widely used in industrial applications to control a wide variety of
processes. A simple closed-loop control uses a feedback signal from the process (such as,
temperature, pressure and speed) and a desired value or setpoint. The control system
compares the two values and derives an error signal. The error signal is used to control the
Inverter and motor to reduce the error.
The error signal processing can be very complex because of the delays in the system. The
error signal is processed using a Proportional and Integral differential (PID) controller whose
parameters can be adjusted to optimize the performance and stability of the system.
The PID controller wizard guide the user through the PID setting-up process.

Open-loop pump

The purpose of this application is to maintain a constant level of fluid in a pumping system
and reacting to maintain the pre-determined level even if fluid is being drawn from the
system.
