Stepper and servo motors are two special types of motors that require special input/output modules in a PLC system.

Explanation:
Motion control needs interfaces that can handle precise timing, current control, and feedback signals. In a PLC system, stepper and servo motors are typically connected through dedicated motion-control drivers or servo/stepper I/O modules rather than directly to basic PLC outputs. The PLC sends commands (such as position or velocity setpoints, or step/direction signals) to the driver, which then powers the motor, and, for servos, reads encoder feedback to adjust motion in real time. This specialized interface is what enables accurate, synchronized control, making the statement true.
