the previous control location is used as the reference when
the control location changes if the references for the two
locations are of the same type (eg
frequency/speed/torque/PID); otherwise, the actual signal is
used as the new reference.

Source selection (see Terms and abbreviations
Selects Ext1 frequency reference source 2.
For the selections, and a diagram of reference source
selection, see parameter
Selects a mathematical function between the reference
sources selected by parameters
and 28.12 Ext1 frequency
frequency ref1.
Signal selected by 28.11 Ext1 frequency ref1
frequency reference 1 as such (no function applied).
The sum of the reference sources is used as frequency
reference 1.
The subtraction ([28.11 Ext1 frequency
frequency ref2]) of the reference sources is used as
frequency reference 1.
The multiplication of the reference sources is used as
frequency reference 1.
The smaller of the reference sources is used as frequency
reference 1.
The greater of the reference sources is used as frequency
reference 1.
Selects Ext2 frequency reference source 1.
Two signal sources can be defined by this parameter and
28.16 Ext2 frequency ref2. A mathematical function
Ext2 frequency function) applied to the two signals creates an
Ext2 reference. See diagram at
