← TechnologyWhich instability develops if a PLC executes ladder logic faster than an actuator's mechanical response time?
A)Kinematic oscillation within the system✓
B)Communication delay affecting network stability
C)Thermal runaway in processor elements
D)Stack overflow within control loop
💡 Explanation
Kinematic oscillation results because the PLC updates commands faster than the actuator responds, causing overshoot and correction cycles initiating hunting behavior, therefore instability rather than stable or delayed adjustments. The PLC executes faster than the system reacts.
