As shown in the illustrated solid-state stepless acceleration starting method graphs, which figure graphs a starting method that features a stepless acceleration ramp-up that is non-adjustable? See illustration EL-0143.
• Compare the wording under the ramp portion of each graph, especially Fixed Ramp Time versus Adj. Ramp Time. • Understand that stepless acceleration means the controlled variable (current, voltage, or speed) increases smoothly, not in discrete jumps. • Identify which method’s ramp cannot be adjusted by the operator and is instead preset by the manufacturer.
• On each figure, what exactly is being ramped (current, voltage, or speed), and is that ramp labeled as fixed or adjustable? • Which graph shows a smooth ramp-up but specifically mentions a ramp time that is not adjustable by the user? • If three graphs clearly allow the ramp time to be adjusted over a time range, what does that suggest about the fourth one?
• Locate the label describing the ramp time on each figure and note whether it uses the word Fixed or Adj. (adjustable). • Confirm that the selected figure shows a smooth (stepless) increase during the start period, not a step change. • Verify that the chosen method’s ramp time is described as approximately 1/4 second and not with an adjustable time range like 3–30 sec or 0–7 sec.
