Parameters 163
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
copied)
Panel reference (03.01 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.

22.13 Ext1 speed function Selects a mathematical function between the reference
sources selected by parameters 22.11 Ext1 speed ref1
and 22.12 Ext1 speed ref2. See diagram at 22.11 Ext1
speed ref1.
Ref1
Ref1 Signal selected by 22.11 Ext1 speed ref1 is used as speed
reference 1 as such (no function applied).
0
Add (ref1 + ref2) The sum of the reference sources is used as speed
reference 1.
1
Sub (ref1 - ref2) The subtraction ([22.11 Ext1 speed ref1] - [22.12 Ext1
speed ref2]) of the reference sources is used as speed
reference 1.
2
Mul (ref1 × ref2) The multiplication of the reference sources is used as
speed reference 1.
3
Min (ref1, ref2) The smaller of the reference sources is used as speed
reference 1.
4
Max (ref1, ref2) The greater of the reference sources is used as speed
reference 1.
5
22.18 Ext2 speed ref1 Selects Ext2 speed reference source 1.
Two signal sources can be defined by this parameter and
22.19 Ext2 speed ref2. A mathematical function (22.20
Ext2 speed function) applied to the two signals creates an
Ext2 reference. See diagram at 28.11 Ext1 frequency ref1.
