Explanation of function and operation
Caution on writing during RUN
During RUN, avoid writing while DRVA (FNC159) instruction is executed (that is, while pulses are output).
Note that if writing is executed during RUN to a circuit block including FNC159 instruction while pulses are output, the
PLC decelerates and stops pulse output.
