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) is
the selection programmed in parameter 90 [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.
