Abstract
The multi-axis motor driving apparatus includes an integrated controller that is configured to discriminate between a drive axis that uses the motor subjected to semi-closed control based on the motor control command and a detection position detected by the encoder and a drive axis that uses the motor subjected to full-closed control based on the motor control command, the detection position detected by encoder and a detection position detected by the linear scale, based on a change amount of the detection position of the encoder or the detection position of the linear scale obtained when the motor subjected to full-closed control is driven.
