Try before you buyHands-on

Learn classic control, VFDs and servo hands‑on, before you stand in front of the panel.

Interactive courses and simulators for the control devices you find in every plant: the same keypad, the same display, the same terminals. Wire it, set the parameters, run the motor, then create a fault and fix it, all in your browser.

How it works

The same steps as on the plant floor, in order

Device simulators open in guided mode: 6 solved exercises, 4 steps each. When you're done, full mode is waiting with a live wiring diagram, the parameter table, faults and references.

  1. Pick the device

    The same model you have at work, or the one you'll be tested on.

  2. Wire it

    Power, motor and control terminals, and the simulator tells you if something's wrong.

  3. Enter the parameters yourself

    From the keypad with the same buttons, and a ✓ as soon as the value is right.

  4. Run the motor

    Start, stop, speed and reverse, and watch current and frequency change.

  5. Create a fault and fix it

    Overload, phase loss, overvoltage… understand the code and reset it properly.

Who it's for

For learners, and for trainers

Students and technicians

  • Practise on the device without fear of burning anything.
  • Learn the keypad before you face it at the plant.
  • Understand each fault code, its cause and its fix.
  • Self-checking exercises, with your progress saved.
  • Every parameter explained in plain language.

Trainers and training centres

  • Put the simulator on the projector and teach live.
  • A real fault in a second, without opening the panel.
  • Ready-made homework students solve from home.
  • Compare the same function across brands in one simulator.
  • Nothing to install: one link for the whole class.
FAQ

Before you ask

Do I need an account?
Not at first. The PowerFlex 525 simulator, the first two lessons plus one middle lesson of every course, and the interview questions are open without an account. The rest of each course opens when you buy it, and stays open for a full year.
Is the site in English?
The site pages are in English. Most lessons and simulators are still in Arabic and are being translated one course at a time; the device screens, terminals and parameter codes are the same as on the real hardware.
Does it work on a phone?
Yes. The courses work on phones, tablets and computers. A bigger screen is more comfortable for the wiring diagram and parameter table, but everything works on a phone.
Do I need to stay online?
Only to open the page the first time. Once a simulator has loaded, everything runs in your browser, so if your connection drops you can carry on.
Is the data 100% identical to the manual?
No, and it's important to know that. Parameter numbers, terminals and fault codes are written from memory and field experience for training, and may differ from your version. Before applying any setting to a real device, check it against the manufacturer's manual for the same model and firmware.
Can I enter the parameters by hand, like on the real drive?
Yes. In guided mode you type every parameter on the keypad with the same buttons, and the simulator shows a ✓ as soon as the value is right. In a hurry? A button enters it for you.
Is my progress saved?
Yes. It's saved in your browser on this device, and if you're signed in, it's also saved to your account so it follows you to any device.
Can I use it in a course or training centre?
Of course. Show the simulator on a projector, teach with it, and have students solve the self-checking exercises.
Is the site part of Rockwell or Siemens?
No. The site is independent and not affiliated with any manufacturer. Names and trademarks belong to their owners and are mentioned only to identify the device you're training on.
