4-2 Function Mode Light Load Detection Signal This function outputs a signal when the Inverter output current has fallen below the C039 set value. 4 The signal is output if the load current has fallen below the C039 set value with the light load signal output mode set to 00 or 01 in C038, and LOC (43) allocated to the multi-function output terminal. This function helps avoid a trip resulting from a falling motor current. Output current C039 Functions 0 [LOC] output 1 0 t t Multi-function Output Terminal ON Delay/OFF Delay This function allows you to set ON/OFF delay times respectively from 0.1 to 100 seconds at the signal output of the multi-function output terminals (P1 and relay).
The following figure shows the output status. 4-70 Data Symbol Function name Status Description 43 LOC Light load detection signal ON Output current is lower than the C039 set value. OFF Output current is higher than the C039 set value. Available input terminals P1-PC, MA-MC (or MB-MC) Required settings C021, C026, C038, C039 Parameter No. Function name Data Default setting Unit C038 Light load signal output mode 00: Enabled during acceleration, constant speed, and deceleration 01: Enabled only during constant speed 01 ⎯ C039 Light load detection level 0.0 to 2.0 × Rated current 0.0: Does not operate Rated current A Parameter No.
