Technology

Which operational error arises when a PLC controlling a pick-and-place robot arm exceeds its program cycle time?

A)Increased motor winding insulation breakdown
B)Inaccurate or missed object placements
C)Unanticipated data loss from encoders
D)Over-pressurized pneumatic gripper failures

💡 Explanation

Exceeding the PLC's program cycle time leads to inconsistent execution of the control loop's inverse kinematics because deterministic timing is lost, therefore robot arm movements become erratic, rather than causing directly motor failures encoder data loss or gripper pressure issues.
