Function
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)
