Chapter 7 Explanation of Functions

 

7 - 73 

7.8.16 Low-current indication (LOC) signal 

The inverter outputs the low-current indication (LOC) signal when the inverter output current falls to the 
low-current indication signal detection level (C039) or less. 
You can select one of the two signal output modes with the low-current indication signal output mode 
selection (C038). In one mode, the LOC signal output is always enabled during the inverter operation. In 
the other mode, the LOC signal output is enabled only while the inverter is driving the motor for 
constant-speed operation.

(*1) When 01 (control circuit terminal) is selected as frequency source setting (A001), there is a case that 
inverter does not recognize the speed as constant value due to sampling. In this case, adjusting is to be 
made by setting C038=00 (valid during operation) or increasing analogue input filter (A016).     
 
 
 
 
 
 
 
 
 
 
 
 
 

7.8.17 Inverter ready signal (IRDY) 

The inverter outputs the inverter ready (IRDY) signal when it is ready for operation (i.e., when it can 
receive an operation command). 
- The inverter can recognize only the operation command that is input while the IRDY signal is output. 
- If the IRDY signal is not output, check whether the input power supply voltage (connected to the R, S, 
and T terminals) is within the range of specification.

7.8.18 Forward rotation signal (FWR) 

The inverter continues to output the forward rotation (FWR) signal while it is driving the motor for forward operation. 
The FWR signal is turned off while the inverter is driving the motor for reverse operation or stopping the motor.
