<P>PROBLEM TO BE SOLVED: To provide a low-speed control method and apparatus for a servo motor. <P>SOLUTION: A low-speed controller for a servo motor 1 for the low-speed control method and device for the servo motor 1 includes: the servo motor 1; an encoder 2; an insertion value computing unit 3; a servo control chip 4; and a power supply module 5. The encoder 2 receives a speed signal from the servo motor 1, and outputs a low-resolution encoder signal after an encoder operation. The insertion value computing unit 3 receives a low-resolution encoder signal output from the encoder 2, changes the low-resolution encoder signal into a high-resolution encoder signal by an interpolation numeric value system and outputs the high-resolution encoder signal. The servo control chip 4 receives the high-resolution encoder signal output from the insertion value computing unit 3, outputs a switch control command through arithmetic processing and includes an internal parameter setting function. The power supply module 5 receives the switch control command output from the servo control chip 4 and transmits the switch control command to the servo motor 1 to adjust the speed of the servo motor 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
