An automated packaging machine utilizes a servo drive. The HMI displays "Following Error Limit Exceeded". The tech checks the PLC and the command position is advancing perfectly, but the machine jams. What is a "following error"?
Answers
AThe physical position of the servo motor lagged too far behind the PLC's commanded position due to a mechanical jam or heavy load
BThe PLC program scanned too slowly to follow the HMI inputs
CThe encoder wires are crossed with the motor power wires
DThe servo drive received a 0V reference signal instead of 10V
