242 Parameters
Frequency input 11.38 Freq in 1 actual value (when DI5 or DI6 is used as a
frequency input).
17
Control panel (ref
saved) Panel reference ( 03.01 Panel reference , see page 168 )
saved by the control system for the location where the control
returns is used as the reference.
18
Control panel (ref
copied) Panel reference ( 03.01 Panel reference , see page 168 ) 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.
19
Other Source selection (see Terms and abbreviations on page 162 ). -
28.12 Ext1 frequency ref2 Selects Ext1 frequency reference source 2.
For the selections, and a diagram of reference source
selection, see parameter
28.11 Ext1 frequency ref1 .
Zero
28.13 Ext1 frequency
function Selects a mathematical function between the reference
sources selected by parameters
28.11 Ext1 frequency ref1
and 28.12 Ext1 frequency ref2 . See diagram at 28.11 Ext1
frequency ref1 .
Ref1
Ref1 Signal selected by 28.11 Ext1 frequency ref1 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 Ext1 frequency ref1 ] - [ 28.12 Ext1
frequency ref2 ]) 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
28.15 Ext2 frequency ref1 Selects Ext2 frequency reference source 1.
Two signal sources can be defined by this parameter and
28.16 Ext2 frequency ref2 . A mathematical function ( 28.17
Ext2 frequency function ) applied to the two signals creates an
Ext2 reference. See diagram at 28.11 Ext1 frequency ref1 .
