Control panel (ref
saved) Control panel reference, with initial value from last-used panel
reference. See section
Using the control panel as an external
control source (page 21 ).
18
Control panel (ref
copied) Control panel reference, with initial value from previous
source or actual value. See section

28.12 Frequency ref2
source Selects frequency reference source 2.
For the selections, and a diagram of reference source
selection, see parameter
28.11 Frequency ref1 source .
Zero
28.13 Frequency ref1
function Selects a mathematical function between the reference
sources selected by parameters
28.11 Frequency ref1 source
and 28.12 Frequency ref2 source . See diagram at 28.11
Frequency ref1 source .
Ref1
Ref1 Signal selected by 28.11 Frequency ref1 source is used as
frequency reference 1 as such (no function applied).
0
Add (ref1 + ref2) The sum of the reference sources is used as frequency
reference 1. 1
Sub (ref1 - ref2) The subtraction ([ 28.11 Frequency ref1 source ] - [ 28.12
Frequency ref2 source ]) of the reference sources is used as
frequency reference 1.
2
Mul (ref1 × ref2) The multiplication of the reference sources is used as
frequency reference 1. 3
Min (ref1, ref2) The smaller of the reference sources is used as frequency
reference 1. 4
Max (ref1, ref2) The greater of the reference sources is used as frequency
reference 1. 5
28.14 Frequency ref1/2
selection Configures the selection between frequency references 1 and
2. See diagram at
28.11 Frequency ref1 source .
