Title:
モータ制御装置
Document Type and Number:
Japanese Patent JP6480316
Kind Code:
B2
Abstract:
The motor control apparatus according to one aspect of the present invention ensures an accurate measurement of the insulation resistance value of the measurement-target motor without being influenced by the decrease of the insulation resistance of the non-measurement-target motor, even when measuring the insulation resistance value of a specific motor among the plurality of motors. The motor control apparatus according to one aspect of the present invention outputs a voltage command to the inverter such that a voltage with an electric potential identical to an electric potential of an earth is applied to the motor where the insulation resistance value is not detected (the non-measurement-target motor)
