Parameter Description MD280/MD280N User Manual
- 176 -
When the frequency source parameter (F0-01) is set to PLC running mode,
it only needs to set the function codes of F8-00 to F8-27 to determine the
running characteristics of PLC.
The symbols of F8-00 to F8-08 determine the running direction of simple
PLC. If the symbol is positive, it indicates that the simple PLC is forward
running; if the symbol is negative, it indicates that the simple PLC is
reverse running.
Simple PLC running is as shown in Fig.6-24:

0: Single running stop
Upon completion of one single cycle of the inverter, it will stop automatically
and will not start until running command is given again.
1: Single running end but the final value remains
Upon completion of one single cycle of the inverter, the inverter will remain
the running frequency and direction of last one phase. After the inverter is
restarted upon stop, it will run from the initial status of PLC.
2: Continuous circulation
Upon completion of one single cycle of the inverter, it will enter next one
cycle and not stop until stop command is given.
