What must the controller know to move to a recorded position?

• A. Position of each axis
• B. The motor torque
• C. The battery level
• D. The load on each axis

Answer: (A)

To move to a recorded position, the controller must know the exact coordinates for each axis saved in that position. A recorded position is a snapshot of where each axis should be, so the controller uses those target coordinates and encoder feedback to drive each axis until the actual positions match the saved values, coordinating motion across all axes.

Torque is about how hard the motors push, not where to go, so it doesn’t define the target point. Battery level doesn’t tell the controller where to move either. The load on each axis can affect how much effort is needed to reach the point, but it isn’t the information that specifies the destination itself.
