Technology

What outcome arises from an industrial robot's thermal runaway of junction temperatures in silicon accelerometers in the presence of sustained high-frequency vibration?

A)Encoder reading position drift
B)Increased drivetrain backlash
C)Reduced PLC cycle time
D)Diminished servo motor energy efficiency

💡 Explanation

Position drift occurs because high frequency heating affects accelerometer bias stability driven by *temperature dependence*, creating small but cumulative integration errors. It accumulates, therefore causing reading errors rather than energy inefficiencies, backlash, or cycle time changes under vibration.
