LIVE ONLINE · SINAMICS G120 · STARTER / STARTDRIVE · PROFINET & MODBUS RTU
A focused live online drive course for maintenance, panel and commissioning engineers. Start with how a VFD actually produces variable frequency, wire and parameterise the SINAMICS G120, commission it from its own terminals using connection macros, then control it from a Siemens PLC over PROFINET and Modbus RTU. Finish with parameter backup, drive replacement and a repeatable troubleshooting sequence.
Online batch 7:30 PM–9:00 PM · Sunday batch 11:00 AM–5:00 PM
See the drive software, hardware and practical engineering topics used at each stage of the online Siemens VFD training path. Select a module to view exactly what you will work with.
Training progression: Module 01 explains how the drive works and how it is wired and parameterised, Module 02 commissions it from its own terminals with the G120 connection macros, Module 03 hands control to the PLC over PROFINET and Modbus RTU, and Module 04 covers backup, replacement and structured fault finding.
View Detailed Drive Training Contents →The drive course is organised as four practical modules covering 18 SINAMICS G120 training topics. Every topic below is a written guide you can open before or after the live session — from drive working principle, wiring and parameter setting through connection macros, PLC control over PROFINET and Modbus RTU, and backup, restore and troubleshooting on site.
Understand what happens inside the drive, wire the SINAMICS G120 control terminals correctly and set motor, ramp and limit parameters in a commissioning order that does not trip the drive.
How a drive builds a variable frequency output through the rectifier, DC bus, IGBT inverter and PWM switching, and why the V/f ratio decides motor torque.
View training topic →02Enter motor nameplate data, ramp times, current and torque limits and the control source in the sequence that avoids nuisance trips on first start.
View training topic →03Wire the control supply, digital inputs and 0–10 V / 4–20 mA terminals of the G120, then map every terminal to the drive parameter that reads it.
View training topic →Commission the drive from its own terminals: preset speeds, analog speed reference, two-wire and three-wire start, stop and reverse control using the standard G120 connection macros.
Run two and four preset speeds from digital inputs using connection macros 1 and 3, with the setpoint parameters behind each selection.
View training topic →02Take a 0–10 V or 4–20 mA speed reference from a potentiometer or PLC analog output and scale it to drive frequency with connection macro 12.
View training topic →03Maintained-contact start and direction control from two digital inputs, and where macros 17 and 18 actually differ on a running machine.
View training topic →04Momentary start, stop and reverse pushbutton control with macros 19 and 20 — the wiring most retrofit and panel upgrades expect.
View training topic →Move from terminal control to network control: telegram selection, control and status words, one reusable function block for every drive, PROFINET addressing and diagnostics, and serial Modbus RTU drive control.
Choose the telegram with p0922, compare types 1, 20, 352 and 999, and map the cyclic input and output addresses in the PLC project.
View training topic →02Decode every control word and status word bit, and decide when cyclic PZD data is enough and when the PKW parameter channel is needed.
View training topic →03Build a single reusable function block that starts, stops, ramps, reverses and monitors every G120 on the line over PROFINET.
View training topic →04Assign device names and IP addresses to drives, set update times and read the PROFINET diagnostics that explain a failed startup.
View training topic →05Compare the two Siemens drive networks on speed, topology, wiring and diagnostics before selecting one for a new or retrofit panel.
View training topic →06Wire the CB1241 RS485 board, set the port parameters and drive the G120 with MB_MASTER read and write logic.
View training topic →07Frames, function codes, register addressing and wiring differences that decide how a drive is polled on serial or Ethernet.
View training topic →Close the loop with maintenance practice: upload a parameter backup, restore it to a replacement drive, compare online values against the offline project and work through faults in a repeatable order.
Go online with STARTER and upload a complete G120 parameter set to the PC as a safe, restorable project backup.
View training topic →02Restore a saved parameter set to a drive and return a replacement unit to service without commissioning it from scratch.
View training topic →03Compare live drive values against the offline project to find parameter changes that were made on the panel and never saved.
View training topic →04Work through drive trips, fault and alarm codes, motor problems, wiring faults and parameter mistakes in a repeatable diagnostic order.
View training topic →The practical platform is the SINAMICS G120 with a PM240-2 power module and CU240E-2 control unit. The same commissioning method, parameter logic and communication concepts carry over to G120C, V20 and other SINAMICS drives you may have in the plant.
No. Parameter work is done in STARTER or SINAMICS Startdrive as an offline project, and every commissioning step is demonstrated live on a real G120 and motor panel shared on screen. A personal drive or trainer kit is useful for practice but is not required.
STARTER and SINAMICS Startdrive for drive commissioning and backups, and TIA Portal when the drive is controlled from a Siemens PLC over PROFINET or Modbus RTU. Installation and version options are explained before the practical topics begin.
Yes. Macros 1 and 3 for fixed speed setpoints, macro 12 for analog speed reference scaling, macros 17 and 18 for two-wire control and macros 19 and 20 for three-wire start, stop and reverse control are each configured and tested.
Yes. Telegram selection with p0922, control and status word bits, PZD and PKW data, one reusable function block for PROFINET drive control, PROFINET device addressing and diagnostics, and serial Modbus RTU control through the CB1241 board are all included.
Yes. Learners upload a full parameter set to the PC, restore it to another drive, compare online values against the offline project to find unsaved changes, and follow the procedure used when a failed drive is replaced on site.
Yes. Fault and alarm codes, overcurrent and overvoltage trips, motor and cable checks, analog reference problems, communication loss and common parameter mistakes are covered as a structured diagnostic sequence rather than trial and error.
Maintenance and service engineers, panel and commissioning engineers, electrical technicians and PLC programmers who need drive control, plus students from electrical, electronics and instrumentation streams who want practical drive skills.
The weekday online batch runs from 7:30 PM to 9:00 PM and the weekend batch runs on Sunday from 11:00 AM to 5:00 PM. The 18 drive topics are usually covered in a short focused schedule, and the pace can be adjusted for corporate or in-plant groups.
Send your requirement for live online Siemens VFD training. Mention your drive model (G120, G120C, V20 or another SINAMICS family), whether the drive is controlled from terminals or from a PLC over PROFINET or Modbus RTU, and your current experience so the sessions can be aligned to your panel. Online batch runs 7:30 PM to 9:00 PM on weekdays and 11:00 AM to 5:00 PM on Sunday.
Explore the four drive modules, STARTER and Startdrive setup, G120 hardware used in the sessions and the online batch options.
