Abstract
A rotation electric machine controller includes: a torque command value acquisition section that acquires a torque command value for a rotation electric machine; and a setting section that sets a negative limit value limiting a d-axis current command value. The setting section sets the limit value having a larger absolute value in a case where the torque command value is large, in comparison to a case where the torque command value is small.
