“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 OIM
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 or Hand/Auto OIM operation.
