4.1.2. Operation with F330=2, 4, 7 or 9 (automatic mode)
It is a mode of light-load high-speed operation with automatic light-load high-speed operation frequency (F341)
when light-load high-speed operation selection F330=2, 4, 7 or 9 (automatic mode) is set.
F330=2 or 7 : Continuous automatic mode
F330=4 or 9 : Enabled-terminal effective automatic mode
F330=4 or 9 is the setting of 2 or 7 plus the enabling signal of light-load high-speed operation function.
The following example indicates the enabling signal assigned to S4 terminal:
In case of using no light-load high-speed operation enabling signal (F330=2 or 7), the operation is under
continuously-enabled condition, which is the same as the operation during S4 terminal continuously ON in the
above chart.
When the enabling sinal is turned OFF during light-load high-speed operation, light-load high-speed operation will
be stopped, to operate with the directed normal speed value.
In case of OFF input, heavy load detection will be stopped, to start constant-speed load judgement after light-load
high-speed operation load waiting time, which commences a measurement when the directed speed value is
achieved.
