• This signal will be output when the output current falls to or below the Low Current Detection Level
(C039).
• In the Low Current Signal Output Mode (C038), select whether to enable the function during
acceleration and constant speed or only during constant speed.
• Set the Multi-function Output P1 to P5 Selection (C021 to C025) or the Multi-function Relay Output
(MA, MB) Function Selection (C026) to 43 (LOC) to enable this function.

*1. When the Frequency Reference Selection (A001) is set to 01 (Control circuit terminal block), the signal may not
be judged as a constant speed depending on the sampling condition. In this case, set C038 to 00 (Enabled
during acceleration/deceleration and constant speed) or increase the value set in the Analog Input Filter (A016).
