2: Simple PLC conditionally effective
When LED Units is selected to 1 (PLC effective), after the inverter has started, at
the frequency channel priority allowed status, the inverter will enter the simple
PLC running status.
When the LED Units is selected to 2 (PLC conditionally effective), when external
PLC input terminal is effective(PLC input terminal is selected by parameter [F1.08]
～[F1.11]), the inverter will run at the simple PLC mode; when the external input
terminal is void, the inverter will automatically enter the frequency setting mode
with lower priority.
LED Tens: Selection of simple PLC running mode
0: Single cycle mode
The inverter will firstly runs at the set frequency of the first-section speed, and
outputs frequency at each speed according to setting time. If the set running time is
0 at certain section of speed, it will skip over this speed section. The inverter will
stop output after end of one cycle, and will not start the next cycle unless the
effective running command is input again.
1: Single cycle stop mode
The basic running way is the same as the mode 0, and the difference is that the
inverter firstly reduces the output frequency to 0 according to the specified
acceleration time after completion of running at certain speed, and then outputs the
next section of frequency.
2: Mode of keeping final value
The basic running way is the same as the mode 0. After the completion of the single
cycle, the inverter will not stop after completion of a single cycle and continues
running at the last speed for which the time is not set to zero. Other process is the
same as model 1.
3: Keeping setting value mode
The basic running way is the same as the mode 0. After the completion of the single
cycle, the inverter will not stop after completion of a single cycle and continues
running at the last speed for which the time is not set to zero. Other process is the
same as model 1.
