5.3. SinCos-Inputs
If the operational mode is set for using SinCos encoders (see chapter 7.4.1 / Parameter 000), the unit
will accept SinCos input signals with 1 Vpp and 2.5 V DC-offset at the 9-pin SUB-D connectors [X6]
and [X7].
It is mandatory to connect up always all existing signal lines (SIN+, SIN-, COS+ and COS-). The
internal SinCos encoder signal monitor verifies the Common Mode range of each signal line and is
capable to detect cable fractures.
An evaluation option for any existing reference signals (REF+ and REF-) is not applicable.
All input lines are already terminated by internal 120 Ohm load resistors.
The SinCos encoder must use the corresponding encoder supply at pin 4 and pin 5 of the connector
(see chapter
5.2 ).
