ABB ACS380 Series - Page 161

Parameters 161
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).
