7-8-18 Low Current Signal (LOC)
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 Selection (C038), select whether to have the inverter output this sig-
nal constantly during run or only during constant speed operation.

Function Selection
*1. When the 1st/2nd Frequency Reference Selection (A001/A201) is set to 01 (Control circuit terminal block (An-
alog input)), 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).
7-8-19 Fatal Fault Signal (MJA)
If any of the following trips occurs, the inverter will output a separate signal besides the alarm signal
(05: AL).
