← TechnologyWhich outcome occurs when a PLC controlling robotic arm movement contains excessive 'ladder logic'?
A)Reduced positional accuracy occurs✓
B)Overtorque motor current limiting
C)Encoder signal phase offset
D)Increased motor thermal capacity
💡 Explanation
The decreased responsiveness in the PLC, due to longer scan times from excessive ladder logic, causes reduced positional accuracy because it delays real-time corrections during movement using inverse kinematics; therefore, the arm undershoots/overshoots rather than issues regarding the motor's electrical characteristics.
