Soft Start

"Soft Start" mode is provided to start the pump after a protracted
stop of the TwisTorr 404/704/804 FS. This allows a better grease
distribution in the bearings.
The "Soft Start" mode is disabled by default. The "Soft Start" mode
can be activated by a suitable software, by Remote I/O or by Front
Panel command (see the paragraphs "INTERCONNECTIONS" and "RS
232/485 COMMUNICATION DESCRIPTION"). "Soft Start" frequency
steps are the followings: 200 Hz, 300 Hz, 680 Hz, 714 Hz and 825 Hz.
The pump remains at each step for a period of 900 s except the first
that last 300 s. A fail condition occurs if the pump is not able to
properly spin up the driving frequency (Too High Load Error).
