When a communication error is detected while Pr.502 = "3," the alarm (LF) is output to an output terminal of the inverter. To use the LF signal, assign the
function to an output terminal by setting "98 (positive logic) or 198 (negative logic)" in Pr. 190 or Pr. 192 (Output terminal function selection).
