What is the speed in Segment 2 of the profile?

• A. Ramp-up
• B. Constant speed
• C. Ramp-down
• D. Variable

Answer: (B)

In motor control speed profiles, you typically see three parts: ramp-up (speed increasing), a middle region where the speed is held steady, and ramp-down (speed decreasing). Segment 2 is the middle region, so the speed stays the same during this segment. On a speed-versus-time view, that appears as a flat, horizontal line, indicating no change in velocity while the system maintains the set speed. Ramp-up would show an upward slope, ramp-down a downward slope, and a variable segment would imply ongoing changes in speed within the segment. So the speed in Segment 2 is constant.
