204 Parameters
22
22 Speed reference
selection
Speed reference selection; motor potentiometer settings.
See the control chain diagrams on pages 442…446.
22.01 Speed ref unlimited Displays the output of the speed reference selection block.
See the control chain diagram on page 445.
This parameter is read-only.
-
-30000.00…
30000.00 rpm
Value of the selected speed reference. See par.
46.01
22.11 Ext1 speed ref1 Selects Ext1 speed reference source 1.
Two signal sources can be defined by this parameter and
22.12 Ext1 speed ref2. A mathematical function (22.13 Ext1
speed function) applied to the two signals creates an Ext1
reference (A in the figure below).
A digital source selected by 19.11 Ext1/Ext2 selection can be
used to switch between Ext1 reference and the
corresponding Ext2 reference defined by parameters 22.18
Ext2 speed ref1, 22.19 Ext2 speed ref2 and 22.20 Ext2
speed function (B in the figure below).
