• To prevent the repetitive on/off operation of the signal due to load fluctuation near the detection range, Pr.1492 Load
status detection signal delay time / load reference measurement waiting time can be used to set the delay time. Even
when a fault is detected out of the detection range once, the warning is not output if the characteristics value returns to the
normal range from a fault state within the output delay time.

• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
