Course project, about 12 hours

Eight drives in a hospital plant room: select, set up and prove the saving

Plan a drive retrofit for the eight pumps and fans of a hospital plant room. Select the drives, set up one drive on the ATV320 in SoMove, record its commissioning and prove the energy saving with the affinity laws. You deliver the motor and drive list, one parameter set, its I/O list and commissioning record, and the energy report.

Practise what you learn in the free 3D lab

Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.

  • Practise safely, so a mistake costs nothing.
  • The lab checks your work like a site test, so you know when it is right.
  • Free, in your browser, with nothing to install.

Why learn with EDWartens

  • Free from the first lesson to the final assessment.
  • Practice in a free 3D lab in your browser, with nothing to install.
  • Video lessons with written notes and a project.
  • An optional certificate that anyone can verify online.
  • Free internships to keep practising afterwards.

Common questions

Do I need a drive?

No, but it helps: any small VFD and a three-phase motor let you do every exercise for real. Without one, SoMove's offline mode lets you configure an ATV320 on the PC.

Is this only about the Schneider ATV320?

The generic modules use a low-cost drive typical of what you meet in the field, and the ATV320 modules show the same functions on a mainstream industrial drive. The concepts transfer to Siemens, ABB, Danfoss, Delta and Allen-Bradley drives.

Is this safe to do at home?

Only with a proper supply, earthing and enclosure, and only if you are competent with mains. The course explains the wiring; it does not make anyone qualified to work on mains.

What certificate do I get, and is it a Schneider qualification?

An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not a Schneider Electric credential and is never described as one.

Is the Variable Frequency Drives course really free?

Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.

Who made the video lessons in the Variable Frequency Drives course?

The creators named in the Credits block at the foot of this page, on their own YouTube channels. EDWartens did not make the videos and the creators are not affiliated with EDWartens. What EDWartens wrote is the study plan, the notes, the practice tasks and the assessments.

How long does the Variable Frequency Drives course take?

Plan on about 12 hours in all, including the video lessons, notes and practice tasks. It is self-paced, so you work through the thirteen modules at your own speed.

Do I have to use the lab?

No. The lab is optional practice. You can skip it whenever you like, and it never blocks your progress, the final assessment or your certificate.

Is the lab free?

Yes. Every lab level for this course opens in your browser, free, with nothing to install.

What topics does the Variable Frequency Drives course cover, module by module?

The Variable Frequency Drives course has 13 modules. It opens with "What a VFD Is and Which One to Buy", goes through "Power Wiring: Supplies, Motors and Phases", "Speed Reference: Potentiometer, 4-20 mA, Presets and Ramps", "Fieldbus on the ATV320: PROFINET, PROFIBUS, EtherNet/IP, POWERLINK" and "Troubleshooting and Testing" and ends with "Final Assessment". The full list with minutes is under "What you learn" on this page.

What can I do after the Variable Frequency Drives course?

After the Variable Frequency Drives course: Explain V/F against vector control and VFD against soft starter and servo; Wire a drive on single-phase or three-phase supply, with shielding and earthing; Set motor nameplate and basic parameters from the keypad. These are the practical outcomes the course is written around, and the final assessment of 15 questions checks them.

What software and hardware do I need for the Variable Frequency Drives course, and does it cost anything?

For the Variable Frequency Drives course, software: None required. SoMove (free from Schneider) optional for the ATV320 modules. Hardware: none required. Any small VFD and a three-phase motor let you do every exercise for real. The course itself is free.

Is the Variable Frequency Drives course suitable for me, and what level is it?

Variable Frequency Drives is rated beginner. Beginner to intermediate. Electrical basics assumed; no drive experience needed. It is written for engineering students, apprentices, technicians and working engineers in electrical and automation maintenance, and takes about 6 hours at your own pace.

Which jobs use the skills from the Variable Frequency Drives course?

Skills from the Variable Frequency Drives course (for example: explain V/F against vector control and VFD against soft starter and servo) are used in roles such as drives engineer, motion control engineer, service technician and commissioning engineer, and in drives and automation engineer work. The course gives you practical evidence of the skill; it does not promise a job, and employers decide on experience and interview.
