7.5.3 Changing Reference Sources
The selection of the active Speed Reference can be made through
digital inputs, DPI command, Jog key, or Auto/Manual OIM
operation. See figure 7.3.
7.5.4 Auto/Manual Control
The Auto/Manual input is not part of the logic commands controlled
by parameter 89 (Logic Source Sel). The Auto/Manual input affects
the speed reference source only.
In Auto reference mode, the reference source is determined by
terminal block inputs (if configured) or a parameter (Speed Ref A
Sel). Only one port at a time can control (own) the reference source.
In Manual reference mode, the reference source for the drive is
based on the port that commanded it most recently. The last source
that commands Manual reference mode will determine the
reference used by the drive.
The Auto/Manual function is available through the terminal block
and LCD OIM function keys. If configured on the terminal block, it is
possible to have the digital input in the "Manual" position but have
Manual being controlled from another port. Because it is an
edge-sensitive signal, the digital input would have to be switched to
"Auto" and then back to "Manual" to re-acquire Manual reference
control.
The Jog reference will bypass the Auto/Manual reference while it is
asserted from the control source. When the Jog reference is
released, the control source reverts to the source that was in effect
before the Jog reference was asserted.
