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.

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.
