Which unsafe outcome arises when a PLC controlling robotic manipulator's emergency stop fails?

💡 Explanation

If the PLC's safety function fails, the emergency stop is ignored, therefore the robotic manipulator continues moving rather than stopping in a hazardous situation. This happens because Override Control Failure prevents motion cutoff and overrides programmed limits.

• Which outcome occurs when an overly aggressive control strategy is applied to hydraulic actuator speed?
• Which problem significantly worsens with increased electromagnetic Interference?
• Which risk increases when rapidly switching between taps on a power transformer?
• Which consequence results downstream when a flow control valve is improperly calibrated in a hydraulic actuator system?
• Which risk sharply increases within electrical substation transformers when internal fault current exceeds circuit breaker interrupting capacity?
• Which outcome occurs when thermal expansion valve fails, restricting flow to HVAC evaporator?
