← TechnologyWhich operational mode occurs when a PLC controlling a robotic paint sprayer experiences a cyclical buffer overflow?
A)Uncommanded nozzle oscillation✓
B)Reduced paint viscosity control
C)Increased servo motor precision
D)Decreased electrostatic charge buildup
💡 Explanation
Uncommanded nozzle oscillation can occur because the PLC continually reverts to a previous state during periods where the buffer overflows, intermittently re-triggering outdated spray settings; therefore, nozzle control becomes erratic, rather than maintaining consistent spray parameters.
