<1> The accuracy of these values depends on motor characteristics, ambient conditions, and drive settings. Specifications may vary with different motors
and with changing motor temperature. Contact Yaskawa for consultation.
<2> Overload protection may be triggered when operating with 100% of the rated output current if the output frequency is less than 6 Hz.
<3> May be shorter due to load conditions and motor speed.
