← TechnologyWhich risk increases when a pneumatic actuator in a high-speed packaging machine exceeds its rated cycle frequency?
A)Valve stiction due to inadequate lubrication✓
B)System-wide latency from depleted air pressure
C)Actuator overheating causing control failure
D)Reduced output force because of over-stroke
💡 Explanation
When a pneumatic actuator exceeds its rated cycle frequency, valve stiction increases because the rapid cycling doesn't allow sufficient time for lubrication to distribute evenly, leading to sticking. Therefore, valve stiction results, rather than latency, overheating, or reduced force each driven by entirely different mechanical issues.
