Protection Design
<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.
<2> Overload protection may be triggered when operating with 165% 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.

The following control methods can be set using drive parameters:
• V/f Control (V/f)
• V/f Control with simple PG (V/f w/ PG)
• Open Loop Vector Control (OLV)
