188 Parameters
Frequency input 1 11.38 Freq in 1 actual value (when DI3 or DI4 is used as a
frequency input).
17
Control panel (ref
saved)
Panel reference (03.01 Panel reference, see page 111)
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 111) 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

See above Control panel (ref copied). 21
Frequency input 2 11.46 Freq in 2 actual value (when DI3 or DI4 is used as a
frequency input).
22
Other Source selection (see Terms and abbreviations). -
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.
