4-2 Function Mode Light Load Detection Signal •This signal is output when output current falls below the light load detection level (C039). •In light load signal output mode C038, you can set whether this output is enabled in any operation mode, or only in constant speed operation. 4 Functions Operation Ready Signal •This signal is output when the Inverter becomes ready for operation (ready to receive the RUN command). •Even if the RUN command is input while this signal is not output, the Inverter does not recognize the RUN command. •If this signal is not output, check if the input power supply voltage (R, S, T) is within the specified range. 4-101 Parameter No.
