These parameters allow you to set up to 15 operating speeds just by switching contact signals externally. Preset-speed frequencies can be set arbitrarily between the lower limit frequency  and the upper limit frequency .

[Setting method]

1) Start/stop

Start and stop control is experienced by the control panel. (Default setting)
