079 [Speed Units]
Selects the units to be used for all speed
related parameters. Options 0 & 1
indicate status only. Options 2 & 3 will
convert/configure the drive for that
selection.
“Convert Hz” (2) - converts all speed
based parameters to Hz, and changes
the value proportionately (i.e. 1800 RPM
= 60 Hz).
“Convert RPM” (3) - converts all speed
based parameters to RPM, and changes
the value proportionately.
