Abstract
A servo driver sets an instruction value for an operation of a servo motor based on an instruction signal from a controller. The servo driver sends the instruction value and a feedback value obtained based on a feedback signal to a safety unit. When at least one of the instruction value and the feedback value sent by the servo driver has an abnormal value, an STO signal is generated and sent to the servo driver. When the STO signal is input to the servo driver, the servo driver stops the supply of electricity to the servo motor.
