🔍 Key Concepts

• Solid-state stepless acceleration and how it controls motor starting current • Difference between controlling current directly vs controlling voltage or speed during start • Effect of having multiple adjustable settings (ramp time, current limit, breakaway current) on how finely starting current can be controlled

💭 Think About

• Look at each graph and ask: is it showing control of motor current, motor voltage, or motor speed during start? Which one most directly shapes the current waveform? • Compare how many independent adjustments each method gives you for the starting current. Does it just limit current once, or can it adjust both the initial and running start current over time? • In which figure could you most easily protect the supply system and motor from high inrush current under different load conditions?

✅ Before You Answer

• Identify which graph(s) have current on the vertical axis instead of speed or voltage • Note which graph(s) show both an adjustable ramp time and an adjustable current limit setting over a wide range of full‑load current • Check if any method adds an extra control, such as adjustable breakaway current, that allows very fine tuning of the current at the instant of starting
