A drive fault code isn't a mystery. It's a sequence of checks — rectifier, DC bus, inverter, motor — done in order.
Variable Frequency Drive
Hands-on training for maintenance and controls teams — drive theory, programming, and a systematic method for diagnosing faults instead of swapping the drive and hoping. Real drives, real induced faults. Delivered on-site or live online.
10
Topics covered end to end, from theory of operation to field troubleshooting
- Theory & power electronics
- Installation & wiring practices
- Programming & parameters
- Speed, torque & process control
- Fault diagnosis & troubleshooting
- Harmonics, grounding & PM
3
Power stages every drive shares — rectifier, DC bus, and inverter — and where each one fails
Harmonics
Grounding and harmonics covered alongside fault-finding, not treated as a separate topic
Multi-Brand
Concepts that carry across manufacturers, not tied to one control panel layout
Everything between "the drive tripped" and "here's why"
What We Train
A drive fault is rarely random — it's the output of a specific power or control stage. We build the session around the whole path: theory, install, programming, control, and diagnosis, using your facility's own drives wherever we can.
Theory & power electronics
VFD fundamentals, theory of operation, and the rectifier, DC bus, and inverter components that do the actual conversion.
Installation & wiring practices
Correct input/output wiring, shielding, and spacing — the install decisions that prevent half the service calls.
Programming & parameters
Setting and adjusting core parameters with intent, instead of copying a value from the last drive that worked.
Speed, torque & process control
How the drive actually controls motor speed and torque, and what that means for the process it's driving.
Fault diagnosis & troubleshooting
Common fault codes traced back to the stage that caused them, using a repeatable method instead of a parts swap.
Harmonics, grounding & PM
Harmonics and grounding considerations, plus building drive checks into an existing preventive maintenance routine.
Built for the people who get the call when a drive faults
WHO SITS IN THE ROOM
This isn't entry-level electrical theory — it's working knowledge for people who already touch drive-controlled equipment and need to program and diagnose it with confidence.
The people who get the call when a drive trips
Hands-on practice with real induced faults, tracing a fault code back to the power or control stage that caused it.
The people building foundational drive knowledge
Learning the rectifier-bus-inverter path and basic parameter structure before diagnostic speed becomes realistic.
The people trying to stop repeat drive failures
Standardizing on a diagnostic method across a team, instead of letting drive troubleshooting depend on who's on shift.
Crews that need one method across sites
The same hands-on curriculum delivered at each facility or live online, so every shift diagnoses drives the same way.
From booking to faster fault-finding in four steps
HOW TRAINING RUNS
Book a date
Tell us your headcount, site, and timeline using the form below.
We scope your drives
We find out which brands and models your floor runs, and what your team already knows.
Program, run, and troubleshoot
Trainees configure real drives, then rotate benches to diagnose faults an instructor has introduced.
Leave with a repeatable method
A documented diagnostic approach and attendance certificates for your training records.
