<P>PROBLEM TO BE SOLVED: To provide a servo system storing the angle-error correction value of a resolver on the motor side and being capable of saving wires. <P>SOLUTION: A rotational-angle detector includes the resolver, a resolver-angle error correction-value storage means, a first interface element, a power supply, and a first terminal changing means. A motor controller includes an oscillation circuit for exciting the resolver, a resolver/digital conversion means, a power supply circuit, a second interface element, an arithmetic means, and a second terminal changing means. The first terminal changing means can change over the resolver exciting lines and the power-supply line and resolver output lines and the wires connected to the first interface. The second terminal changing means can change over the wires for the oscillation circuit and the wires for the power supply circuit and the resolver output lines and the wires connected to the second interface, and a part between the rotational-angle detector and the motor controller can be configured only by as many wires as the resolver exciting lines and output lines. <P>COPYRIGHT: (C)2011,JPO&INPIT |
