Reference Control
“Auto” Speed Sources
The drive speed command can be obtained from a number of different
sources. The source is determined by drive programming and the condition
of the Speed Select digital inputs, Auto/Manual digital inputs or reference
select bits of a command word.
The default source for a command reference (all speed select inputs open or
not programmed) is the selection programmed in [Speed Ref A Sel]. If any
of the speed select inputs are closed, the drive will use other parameters as
the speed command source.
“Manual” Speed Sources
The manual source for speed command to the drive is either the HIM
requesting manual control or the control terminal block (analog input) if a
digital input is programmed to “Auto/Manual.”
Changing Speed Sources
The selection of the active Speed Reference can be made through digital
inputs, DPI command, jog button or Auto/Manual HIM operation.
