Incremental encoder to absolute feedback inputs (pins X3B, X4B)
Incremental encoders can
also
be connected to the inputs
for the
absolute feedback
system.
+IncA = Clk+
-IncA = Clk-
+IncB = Data+
-IncB = Data-
+Ref = Ref+
-Ref = Ref-
This type of connection allows you to achieve considerably higher signal frequencies for the encoder
signals; see section 3.1 Technical details for motion boards, sub-section: Incremental encoder
In the case of AX boards, this function is available from HW Rev. B.
