Parameters 237
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 (e.g.
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). -
26.12 Torque ref2 source Selects torque reference source 2.
For the selections, and a diagram of reference source
selection, see parameter 26.11 Torque ref1 source.
Zero
26.13 Torque ref1 function Selects a mathematical function between the reference
sources selected by parameters 26.11 Torque ref1 source
and 26.12 Torque ref2 source. See diagram at 26.11 Torque
ref1 source.
Ref1
Ref1 Signal selected by 26.11 Torque ref1 source is used as torque
reference 1 as such (no function applied).
0
Add (ref1 + ref2) The sum of the reference sources is used as torque reference
1.
1
Sub (ref1 - ref2) The subtraction ([26.11 Torque ref1 source] - [26.12 To rqu e
ref2 source]) of the reference sources is used as torque
reference 1.
2
Mul (ref1 × ref2) The multiplication of the reference sources is used as torque
reference 1.
3
Min (ref1, ref2) The smaller of the reference sources is used as torque
reference 1.
4
Max (ref1, ref2) The greater of the reference sources is used as torque
reference 1.
5
26.14 Torque ref1/2
selection
Configures the selection between torque references 1 and 2.
See diagram at 26.11 Torque ref1 source.
