186 Parameters
PID 40.01 Process PID output actual (output of the process
PID controller).
16
Frequency input 11.38 Freq in 1 actual value (when DI6 is used as a
frequency input).
17
Control panel (ref
saved)
Panel reference (03.01 Panel reference, see page 108)
saved by the control system for the location where the
control returns is used as the reference.
18
Control panel (ref

Panel reference (03.01 Panel reference, see page 108)
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.

Other Source selection (see Terms and abbreviations). -
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.
