Abstract

PURPOSE:To obtain an excellent cut surface by correcting a error between an electric phase angle at which a resolver is generated and an actual detected mechanical angle by a command input corresponding to one cycle of the electric angle. CONSTITUTION:Command input 10 let phase modulator 6 shift in phase only as much as unit movement, phase discriminator 7 generates an output to put servomotor 9 into operation, and through mechanical coupling mechanism 11, resolver rotor winding 4 moves and stops where it is in phase with phase modulator 6. Command input 10 is supplied to ring counter 12 as well, which counts up or down according to the direction of minimum movement in one cycle of an electric resolver angle when receiving a shift input or pulse equivalent to the minimum movement command shift value. This output is supplied by error correcting command unit 13 to detection circuit 14 as an error correction shift input, so that detection circuit 14 will supply an exciting output of a phase shifted correspondingly to resolver 2.
