Settings	d20 to d150%	Factory Setting: d130

A setting of 100% is equal to the Rated Output Current of the drive.

During acceleration and steady-state operation, the AC drive output current may increase abruptly to exceed the value specified by Pr.6-02 due to rapid acceleration or excessive load on the motor. When this function is enabled, the AC drive will decrease. The AC drive will only resume acceleration when the current drops below the level specified by Pr. 6-02.
