Everything the course assumes you already know, from what a volt is to how a PID loop works. Start here if electricity, motors or feedback control are new to you.

Everything the PLC-200 labs assume: what a PLC is and how it scans, the S7-200 memory, STEP 7-Micro/WIN from installation to download and monitoring, ladder, timers and counters, GRAFCET and its translation to SCR steps, statement list, pulse outputs, and how to test a program so it fails safe. Every lesson runs your programs on a virtual PLC-200.

How a load decides the motor: load families, the induction, synchronous and DC motor in depth, heating and duty cycles, nameplates, and a step-by-step selection with the Tutorial 1.2 catalogue.

The machines that move fluids, and the drives that make them efficient: pump and system curves, the energy cost of each flow-control method, the five ways to start a motor, soft starters, variable-frequency drives, and pump stations under PID control.

Vertical transport, where gravity drives the load: counterweights and roping, the four quadrants on a real lift, S-curves and leveling, braking resistors and regenerative drives, the fail-safe brake and safety chain, and the mine hoist.

Three motions with different loads: the gravity-driven hoist and the inertia-driven trolley and bridge. Duty groups, dual braking and brake-lift sequencing, anti-sway, skew and load monitoring, power feeds and operator controls.

From one suspended load to a steady flow: belt pull and what sizes the drive, the belt as a spring, load sharing by master-slave or droop, protection and start/stop sequencing, escalators, ropeways and the bucket-wheel excavator.

The principles of Chapters 1–5 across industry: reversing mills, arc furnaces, kilns, drilling and winders; what surrounds the drive (harmonics, cables, protection, availability, commissioning); and the capstone mini-project with its rubric.
