The drive operates according to the setting for Pr.06-73 when the output current is lower than the setting for Pr.06-
71 and when the time of the low current exceeds the detection time for Pr.06-72. Use this parameter with the
external multi-function output terminal setting 44 (low current output).
The low current detection function does not execute when drive is in sleep or standby status.
