Cautions
• It is not permitted to use an RS (FNC 80)/RS2 (FNC 87)/FLCRT (FNC300)/FLDEL (FNC301)/
FLWR (FNC302)/FLRD (FNC303)/FLCMD (FNC304)/FLSTRD (FNC305) instruction and an
IVCK (FNC270)/IVDR (FNC271)/IVRD (FNC272)/IVWR (FNC273)/IVBWR (FNC274) instruction for the
same port.
• Two or more inverter communication instructions (FNC270 to FNC274) can be driven for the same port at
the same time.
