Siemens Tia Portal - S7 1200 PLC -Basic-2

vfd control(v20)-high speed counter(encoder)-analog-digital-input/output-KTP 400 HMI

If you look at the industry, you can see Variable Frequency Drive (VFD) systems everywhere. Therefore, we must understand how to control VFD systems efficiently.

In this course, we will control Siemens Sinamics V20 VFD systems using the powerful S7-1200 PLCs. This practical approach provides crucial hands-on experience.

Every VFD system has its own unique parameter list. We will check the basic parameter list for the Sinamics V20. VFD systems can be controlled in several ways, allowing for great flexibility:

1. Operator panel on the VFD system

2. Terminals on the VFD system (analog/digital input and output)

3. Communication protocols (USS, Modbus, Profinet, Profibus, etc.)

We will primarily focus on methods 1 and 2 to build a strong foundation. We will do practical examples using real equipment to solidify your learning.

Equipment list for hands-on exercises:

1. S7-1214 CPU

2. KTP 400 HMI

3. Sinamics V20 VFD

4. AC Motor

5. Encoder (100 pulse)

6. WinCC Scada V13

We will realize the necessary connection between the PLC and VFD. We will control the motor using both analog and digital inputs/outputs. Furthermore, all operations will be performed with the KTP 400 touch screen operator panel. To monitor motor speed accurately, we will utilize the encoder for rotation information. We will also start to use the essential WinCC Scada software for advanced monitoring. We will finish our course by comprehensively revising all our knowledge. We must learn to operate the system with simple signals first. Then, we can use more complex signals like communications.
