Publication number: 20240231314Abstract: A servo driver is configured to drive a first motor and be communicatively connected to a different servo driver. The servo driver and a first sensor that is configured to detect a parameter relating to displacement of a first drive target driven via an output axis of a first motor are in an arrangement such that a detection signal from the first sensor is received by the servo driver.
