MOTOR CONTROL SYSTEM, POSITION DETECTOR AND SERVO AMPLIFIER

摘要

PROBLEM TO BE SOLVED: To ensure optimal cogging correction regardless of combination of a servo motor and a servo amplifier by eliminating the need for work of no-load operation before a servo motor is assembled in a machine. SOLUTION: A position detector 50 connected with a servo motor 110 is provided with a memory 61 for storing the cogging torque correction data of the servo motor 110 and correction data is transmitted from a correction data transmitting/receiving section 62 to a servo amplifier 10. The servo amplifier 10 receives correction data from the position detector 50 and corrects cogging torque using that data.
