ABSTRACT:
A servo driver (3) includes: an input section (11) for input-specifying the type of an encoder (7) at the side of an actuator (2); a control section (13) for generating a control signal (12) according to the type input; and an encoder signal processing IC (20) for switching the input port to which reception data (7S) is input form the encoder (7) according to the control signal (12). The encoder signal processing IC (20) is compatible with processing of an output of either a line-saving encoder or a 14-line encoder and can realize a highly general-purpose servo driver. This can solve the problem that the servo driver should be modified according to the type of the encoder mounted on the actuator.
