Altitude Derating
The drive standard ratings are valid for an installation altitude up to 1000 m. If the altitude exceeds 1000 m both the drive
rated voltage and the rated output current must be derated for 1% per 100 m. The maximum altitude is 3000 m.

<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 133% of the rated output current if the output speed is less than 6 Hz.
<3> Ground protection cannot be provided when the impedance of the ground fault path is too low, or when the drive is powered up while a ground
fault is present at the output.
