SPEED COMMAND
Spd Mode & Limits
079 [Speed Units]
Selects the units to be used for all speed
related parameters. Options 0 & 1
indicate status only. Options 3 & 4 will
convert/configure the drive.
“Convert Hz” - converts all speed based
parameters to Hz, and changes the value
proportionately (i.e. 1800 RPM = 60 Hz).
“Convert RPM” - converts all speed
based parameters to RPM, and changes
the value proportionately.
