Outcome
What you will be able to do
Explain what a VFD does and choose one; wire it on single- or three-phase supply; set basic parameters; run in 2-wire, 3-wire and push-button control with reverse; give the speed reference from a potentiometer, 4-20 mA or presets with ramps; use relay and analog outputs; control the drive from a PLC by terminals, analog and Modbus RTU; connect an ATV320 over PROFINET, PROFIBUS, EtherNet/IP and POWERLINK; build constant-pressure pumping; set safety, fault reset and passwords; troubleshoot.
- 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
- Run in 2-wire, 3-wire and single-button control with forward and reverse
- Give the speed reference by potentiometer, 4-20 mA, presets and ramps
- Wire relay and analog outputs to a PLC and control the drive from a PLC
- Control the drive over Modbus RTU and connect an ATV320 to PROFINET, PROFIBUS and EtherNet/IP
- Configure constant-pressure pumping, safety functions and fault reset, and troubleshoot
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.

EDWartens Lab
Practise this in the EDWartens Lab
Wire a variable frequency drive in the Panel Lab: power in and out, safe torque off, run command, speed reference and fault relay, then prove it.
Works alongside Variable Frequency Drives: Wiring, Programming, PLC and Network Control. The Lab is control panel build practice in your browser: no install, no hardware, free to use. Sign in as a learner and it opens with your account.

Why practise in a 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.
Certificate
