03.01 Panel reference
Panel reference (
for 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.

frequency reference 1 as such (no function applied).
The sum of the reference sources is used as frequency
reference 1.
28.11 Ext1 frequency ref1
The subtraction ([

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.
