Control
20. Positioning Control – FNC150 to FNC159
FNC150 to FNC159 provide positioning instructions using the built-in pulse output function of the PLC.
→ For details, refer to the Positioning Control Edition manual.
Caution on writing during RUN
During RUN, avoid writing while any positioning control instruction (FNC150, FNC151, or FNC156 to
FNC159) is executed (that is, while pulses are output).
If program write is executed during RUN to a circuit block including a target instruction below while pulses are being
output, the PLC executes the operation shown below.
FNC159) is executed (that is, while pulses are output).
If program write is executed during RUN to a circuit block including a target instruction below while pulses are being
output, the PLC executes the operation shown below.
