1. A servo amplifier system performing a multi-axis control for multiple axes, wherein
the multiple axes include:
a first axis group which an axis to be locked, at the time of power supply abnormality in the multi-axis control, belongs to, and
a second axis group which an axis to be subjected to servo-off belongs to, the servo-off being made before the axis belonging to the first axis group is locked at the time of the power supply abnormality.
