Parameters 219
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.
Zero
Zero None. 0
AI1 scaled 12.12 AI1 scaled value (see page 189). 1
AI2 scaled 12.22 AI2 scaled value (see page 191). 2
FB A ref1 03.05 FB A reference 1 (see page 168). 4
FB A ref2 03.06 FB A reference 2 (see page 168). 5
EFB ref1 03.09 EFB reference 1 (see page 168). 8
EFB ref2 03.10 EFB reference 2 (see page 169). 9
Motor
potentiometer
22.80 Motor potentiometer ref act (output of the motor
potentiometer).
15
PID 40.01 Process PID output actual (output of the process PID
controller).
16
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). -
22.19 Ext2 speed ref2 Selects Ext2 speed reference source 2.
For the selections, and a diagram of reference source
selection, see parameter 22.18 Ext2 speed ref1.
