Which risk increases when hydraulic actuator velocity exceeds design limits in precision robotics?

A)Setpoint overshoot due to inertia
B)Stall current increase in the DC motor
C)Thermal runaway from fluid compression
D)Increased backlash due to link wear

💡 Explanation

When actuator velocity exceeds the design limits, the mechanism of inertial overshoot occurs because the increased kinetic energy resists deceleration near the target position, leading to higher positioning error. Therefore setpoint overshoot becomes greater, rather than motor stall, thermal runaway, or backlash changes, which involve different mechanical properties.
